C-Space-Based Toolpath Generation for Five-Axis Controlled Machining with Special Tools
Ken Okamoto; Koichi Morishige
International Journal of Automation Technology, Fuji Technology Press Ltd., 18, 5, 679-687, 05 Sep. 2024, Peer-reviwed, This paper describes a method for generating toolpaths based on machining strategies for five-axis controlled machining using special tools. Traditionally, most toolpath generation studies focused on ball-end mills, proposing strategic methods to achieve high-quality machining while avoiding tool interference. Recently, special finishing tools with large cutting edge radii have gained interest for achieving higher machining efficiency. These special tools can produce smooth finished surfaces even with large pick-feed widths, leading to higher productivity. However, unlike conventional machining with ball-end mills, five-axis controlled machining using special tools lacks standardized work design procedures. This study proposes a generic tool-geometry data format for defining special tool geometries and a method for generating toolpaths using this data format. This method strategically treats special tools as conventional ball-end mills. Consequently, five-axis controlled machining for new tool geometries can be achieved using existing operational procedures. To generate toolpaths, this study utilizes a two-dimensional configuration space (C-Space). For special tools with multiple cutting edge radii, the relationship between the tool posture and cutting edge contact point is clarified by mapping the cutting edge radius information onto the C-Space. By employing this mapped cutting edge information, we can determine the interference-free tool posture corresponding to the chosen cutting edge section based on the machining strategy. Finally, the paper presents machining simulations and experiments conducted to confirm the effectiveness of the proposed method.

Generation of a Robot Program and Determination of an Optimal Workpiece Placement Considering the Manipulability of Industrial Robots
Kei Moriguchi; Takuya Mizokami; Koichi Morishige
Corresponding, International Journal of Automation Technology, Fuji Technology Press Ltd., 16, 6, 870-878, 05 Nov. 2022, Peer-reviwed, Invited, Various operations in the production sites of manufacturing industries are being automated using industrial robots instead of operators. In recent years, an offline teaching method for robot motion has been implemented, where programs are generated in a work environment that is reproduced virtually inside a computer. However, the robot program developed using the offline teaching method can pass through singularities or suddenly change the robot’s posture, making the robot incapable of performing safe operations. To achieve optimal operation, the operator must determine the workpiece placement and create a robot program through trial and error. In this study, we proposed a method that uses manipulability to generate a program that commands the robot to move without passing singularities or changing the robot’s posture. Manipulability is quantitatively evaluated as an indicator of a robot’s ability to move its end effector in arbitrary directions. We proposed another method to determine the optimal workpiece placement for robot operations that can maximize the sum of manipulability during the operation. We implemented the aforementioned methods in an offline teaching system. We applied the developed system to a welding operation and verified its effectiveness by conducting motion simulations. The developed system was able to generate a practical robot program that maintained high manipulability and did not cause sudden changes in the posture or pass singularities. The developed system was able to simultaneously determine the optimal workpiece placement for the task, thereby confirming the usefulness of the proposed method.

神田倫之; 森重功一
精密工学会誌, The Japan Society for Precision Engineering, 78, 1, 969-973, Oct. 2016, Peer-reviwed, In case of the five-axis controlled machining, there is interference problem among tool, workpiece, jig, machine structures such as table and spindle. In this study, these 3D models were loaded to CAM, and, moved to position corresponding to candidates of all tool postures on tool path. Then, by performing interference judgment, candidates of tool postures without interference were calculated. Therefore, tool path without interference was generated. When interference judgment is performed, process time was shortened by parallel processing using GPU and polygon model. Additionally, this CAM was corresponded to all types of five-axis controlled machining, table-tilting type, table/spindle-tilting type, and spindle-tilting type, and, improvement of general versatility was conspired. Finally, as the result of the machining simulation using all types machining, the effectiveness of the devised technique was confirmed.

Koichi Morishige; Miharu Nakada
FACTORIES OF THE FUTURE IN THE DIGITAL ENVIRONMENT, ELSEVIER SCIENCE BV, 57, 649-652, 2016, Peer-reviwed, This study aims to develop the turning system using a haptic device as a new operation interface that enable to cope with machining complicated shapes intuitively. The haptic device is very useful for interface because it can provide the user with sensations of physical force, such as shocks or vibrations, in the virtual space. In previous reports, we have already proposed some applications of the haptic device to interface of CAM software and machine tool. Operating the virtual tool with the haptic device, the sensations of force function guides the operator to suitable operation by limiting tool movement, the operator can make NC program for complicated turning process that will be difficult for conventional methods. In this report, the trial system developed in the previous research that could cope with simple turning operations was extended to cope with more complicated operations. An original tool with special shape was made for a target shape, and a function of tool collision avoidance that can cope with the special tool was also developed. The usefulness of developed system was actually confirmed through some machining experiments using NC program that was generated by using the system. (C) 2016 The Authors. Published by Elsevier B.V.

International Journal of Automation Technology, Fuji Technology Press, 8, 3, 445-451, 2014, Peer-reviwed, This study aims to develop a turning system that uses a haptic device as a new operation interface to enable even beginners to operate a turning machine easily and safely. The haptic device is important because it can provide the user with sensations of physical force, such as shocks or vibrations, in the virtual space. These sensations of force function to guide the operator to suitable operation by limiting tool movement. In this study, a system is developed to teach, using the haptic device, the toolmovements in machining shapes in a virtual space. The tool movement that is taught is output as the movement of turning machine, and the actual machining is performed. In the our system, we have implemented a function that avoids interference between the tool and workpiece and limits the depth of cut in order to avoid excessive cutting. The usefulness of developed system is confirmed through machining experiments.

岡本謙; 森重功一
日本機械学会論文集 Ｃ編, The Japan Society of Mechanical Engineers, 79, 803, 2585-2596, Jul. 2013, Peer-reviwed, This study is related to automation of polishing process by using an industrial robot. In polishing process, full automation of polishing operation has not been achieved due to the difficulty in visual inspection. Judgment of polishing sufficiency has been performed by skilled workers. In this study, the surface after milling process is the target for polishing. In the previous report, the generation of robot program for polishing operation based on CAD data was already proposed. Focusing on the periodicity of cutter mark patterns on milling surface, we proposed an automatic judgment of polished surface quality. This method is based on the image processing which uses Discrete Fourier Transformation. In order to capture images of the polished surface, a CCD camera was mounted on a 6-axis controlled robot hand. However, the image processing method proposed in previous report could not judge the curved cutter mark patterns because the periodicity of those patterns is not uniform. The objective of this report is the development of automatic judgment method for non-periodic cutter mark patterns. We developed a judgment method which uses statistical pattern recognition as a means to judge the existence of cutter marks. As a result, a system that allows the automatic polishing that includes the surface quality judgment is developed.

C-Spaceを用いた5軸制御加工のための工具経路生成 ―スクエアおよびラジアスエンドミルによる加工への対応―
増田拓也; 森重功一
精密工学会誌, The Japan Society for Precision Engineering, 78, 1, 57-61, Jan. 2012, Peer-reviwed, In recent years, 5-axis controlled machine tools attract attention because of the increase in demand for improvements in productivity. Ball end mill is easy to control its location against a cutting surface, and is often used for the 5-axis controlled machining. However, the cutting removal rate of ball end mill is insufficient. Square and radius end mills has the higher removal rate more than ball end mill. On the other hand, the 5-axis controlled machining with square or radius end mill may be difficult compared with the case of ball end mill. In this report, 2-dimensional configuration space that expresses one tool posture by one point on the space was extended to cope with the machining with square and radius end mills. Furthermore, the new tool path generation method was proposed, which can reduce the cutting remains near a character line. As the result of machining simulations, the cutting remains near a character line were reduced, and the utility of the proposed tool path generation method was actually confirmed.

Development of Operation Interface for Machine Tool using 6-DOF Haptic Device - Guidance of Tool Movement using Force Sense
Syuhei Kobori; Koichi Morishige
PROCEEDINGS OF PRECISION ENGINEERING AND NANOTECHNOLOGY (ASPEN2011), TRANS TECH PUBLICATIONS LTD, 516, 337-342, 2012, Peer-reviwed, In the previous report, the operation interface for multi-axis controlled machine tools was developed by using the haptic device that is used in the field of virtual reality and it was changed from a haptic device with 3-DOF to that with 6-DOF. In order to improve the system, more useful functions should be added.
In this report, the function to guide the tool in consideration of the tool's characteristics is developed. The square end mill cannot cut at its bottom part. So, when the bottom part contacts the removal shape, the square end mill should be guided into a posture contacting at the side part by the force sense.
The experiment supposed that the machining of the curved surface had been done. In the case of using the developed function, the number of contacts at the bottom part of the tool was decreased. As a result, the usefulness of the developed function was confirmed.

International Journal of Automation Technology, Fuji Technology Press, 6, 6, 710-716, 2012, Peer-reviwed, In the case of five-axis controlled machining, the machine components such as tables, spindles, and columns take various locations, so interference may occur among machine components. In commercial CAM software used five-axis controlled machining, however, structural interference is not considered. Output Cutter Location (CL) data may therefore cause structural interference. In this report, locations of the machine components where structural interference may occur are calculated and a tool path generation method considering the above-mentioned problem of interference is developed.

Polishing Process Automation by Industrial Robot with Polished Surface Quality Judgment Based on Image Processing - Visual Inspection Based on Pattern Matching -
Ken Okamoto; Koichi Morishige
EMERGING TECHNOLOGY IN PRECISION ENGINEERING XIV, TRANSACTION PUBLISHERS, 523-524, 481-486, 2012, Peer-reviwed, The study deals with automation of polishing process by using an industrial robot. In polishing process, full automation of polishing work has not been achieved because of difficulty in visual inspection. Judgment of whether polishing is sufficient or not has been performed by skilled workers in the present situation. In the previous research, generation of robot program for polishing operation using CAD/CAM was already proposed. In this proposed polishing system, a CCD camera mounted at an end effector of 6-axis control robot, captures image of polished surface. Using polished surface image, we developed automatic judgment of polished surface quality based on image processing which uses discrete Fourier transformation. However, the proposed image processing method cannot judge the tilted or curved cutter mark pattern. The purpose of this study is to develop automatic judgment method for general cutter mark pattern. In this report, we improved proposed judgment method using discrete Fourier transformation, and developed judgment method which uses computer vision. We utilize computer vision as a means to judge existence or nonexistence of cutter marks. As a result, the developed system allows the automatic polishing that includes surface quality judgment.

International Journal of Automation Technology, Fuji Technology Press, 5, 3, 412-419, 2011, Peer-reviwed, In this paper, the original configuration space is applied to generate tool path, which indicate locations of two rotational axes of a 5-axis controlled machine tool. Moreover, A-star algorithm that is one of the methods for route searching is applied to decide tool postures considering the motion of two rotational axes. The developed method can generate tool path limiting the number of used rotational axes, and reducing the moving amount of two rotational axes. Furthermore, the method can generate tool path that avoids the reverse rotation of two rotational axes, which might cause the machining error. As a result, an excellent finished surface is actually obtained, and the usefulness of the developed method is confirmed.

金子 誠; 森重功一
精密工学会誌, The Japan Society for Precision Engineering, 76, 1, 101-105, Jan. 2010, Peer-reviwed, The current CAM software for 5-axis controlled machining does not consider machine tool information when generating tool path. Therefore, the CAM software has the problem of outputting the tool path data that might be changed into the problematic NC data including redundant change and reversal rotation of rotational axes. In this report, the configuration space in that a position of two rotational axes indicated in one point is applied. A-star algorithm that is one of techniques for searching path is applied to decide tool attitudes considering the motion of two rotational axes in 3-dimensional configuration space. The developed method can generate tool path limiting the number of used rotational axes, and reducing the moving amount of two rotational axes. Furthermore, the method can generate tool path that avoids the reversal rotation of two rotational axes that might cause the processing error. Finally, machining experiments were performed for overhang groove shapes. As a result, excellent finished surface was actually obtained, and the usefulness of the developed method is confirmed.

青山一郎; 森重功一
精密工学会誌, The Japan Society for Precision Engineering, 75, 8, 1010-1014, Aug. 2009, Peer-reviwed, The study deals with automatic path planning method for cutting operation using an industrial robot. In general, studies of motion planning for industrial robots are divided in two approaches, considering a robot configuration or a tool configuration. However, in case of cutting operation using an ultrasonic cutter, generation of optimal tool path becomes difficult, because it is required consideration of continuous tool posture, wide movable range of robot, and high tool feed speed. In this study, we propose the use of an original local configuration space that generated by two angles that determine tool posture at each cutting point, and generate tool path using an A-star search algorism based on the evaluations of interference, movable range and mobility of robot that varied according to relationship of tool feed speed and angular speed of each joint. As a result, it is found that the proposed path generation method is more effective than conventional methods.

森重功一; 山本良輔
日本機械学会論文集 Ｃ編, The Japan Society of Mechanical Engineers, 75, 752, 1187-1193, Apr. 2009, Peer-reviwed, Multi-axis controlled machine tool allows us to make complicated products. However, the multi-axis controlled machine tool requires long time from its introduction to the effective use, because its operation requires the special knowledge and a certain amount of the experience. Therefore, the improvement of man-machine interface of the machine tool is indispensable to operate it easily without considering its complicated mechanical characteristic. This study aims at developing the machining system that enable to make complicated shapes more intuitively and efficiently than conventional ways by using a haptic device used in the field of virtual reality as a new operation interface intended for multi-axis controlled machine tools. In this report, some basic functions that the system should fulfill are examined: first, the function of displaying the cutting condition is developed by use of a decomposition model; second, the presentation of cutting sense is realized by calculating the appropriate haptic force; and third, the tool interference avoidance is realized with consideration of the multipoint contact of cutting tool. Moreover, some machining experiments are performed by using cutter locations outputted form the developed program. As a result, the target shapes are actually obtained, the assumption of the proposed method is confirmed.

機械の可動範囲と工具姿勢変化の連続性を考慮した5軸制御加工用工具経路生成法
藤野裕典; 森重功一
精密工学会誌, The Japan Society for Precision Engineering, 74, 12, 1330-1334, Dec. 2008, Peer-reviwed, A lot of techniques of tool path generation for 5-axis controlled machining that consider tool interference are already proposed. However, those methods have outputted impossible tool path for machine tool, because movable range of driving axes of machine tool is not considered. Moreover, discontinuous tool path threatens to cause deterioration of surface quality. This study has been aiming to generate the tool path considering movable range of machine tool and continuity of tool attitude change. We have already proposed the original 2-dimensional configuration space that indicates possible tool attitude at each cutting point. The method proposed in this report searches the shortest tool path using 3-dimensional configuration space that corresponds to available tool attitudes with consideration of tool interference and movable range of machine tool. As a result, usefulness of the devised method was experimentally confirmed.

Feliciano H. Japitana; Koichi Morishige; Yoshimi Takeuchi
MANUFACTURING SYSTEMS AND TECHNOLOGIES FOR THE NEW FRONTIER, SPRINGER, 395-+, 2008, Peer-reviwed, Complex mold or intricate shaped product can be manufactured by rotational cutting tool with an increased in cutting speed, a process now known as high speed cuffing; however, shaving remnants are formed according to the tool shape at the adjoining surfaces or end corner of the product. This limitation is inevitable, especially when employing rotational tool in the process. If this limitation can be removed by cutting, the flexibility of the product form, which can carried out in manufacturing can be extended greatly. This paper presents a new manufacturing method to produce an intricate shaped product utilizing the 6-axis control machining using a non-rotational cutting tool with the application of ultrasonic vibrations. The result of experiment shows that intricate shape product has been manufacture using the new manufacturing method.

5軸制御加工機を利用した割り出し突き荒加工法の開発
平野千尋; 森重功一
精密工学会誌, The Japan Society for Precision Engineering, 73, 11, 1261-1266, Nov. 2007, Peer-reviwed, This paper deals with the rough cutting method using 5-axis control machine tool and the tool path generation method to machine complicated shapes efficiently such as overhanging shape that requires the inclination of cutting tool. In general, conventional rough cutting methods employ the contour milling with 3-axis control. However, these rough cutting methods were not always efficient, because several set-up changes were required to machine complicated shapes. The study proposes the new rough cutting method for 5-axis control machining, which uses a plunge milling that has been used only for 3-axis control machining. Consequently, the rough cutting with the high efficiency of plunge milling and the flexibility of 5-axis control can be realized. In order to achieve the method, it is necessary to generate the tool path in consideration of the tool interference with not only the target shape but also the remained part. Therefore, the study developed the tool path generation method by expanding the method which uses the 2-dimensional configuration space technique. Finally, the developed method is implemented to the original CAM software. As a result, it is experimentally found that the system enables the rough cutting of complicated shapes with 5-axis control with only one set-up.

精密工学会誌, The Japan Society for Precision Engineering, 72, 5, 652-656, May 2006, Peer-reviwed, The 5-axis control machining has a lot of advantages in the machining of complex shapes. The major problem in 5-axis control machining is the tool interference with workpiece. Some commercial 3-dimensional CAM software are already offered, which consider the tool interference problem and allow us the interference-free 5-axis control machining. However, the policy of above CAM software to the tool interference avoidance is that the tool attitude is modified only at where the tool interference is detected. Thus, the tool attitude suddenly changes with the redundant movement. Because such movement cause the over and under cutting, it is necessary to be avoided as much as possible. We have already proposed the tool path generation method for 5-axis control machining using an original configuration space. In the previous paper, the interference-free cutter location data with the least amount of the change in tool attitude was generated while referring to all of the configuration space information at several cutting points. In this study, tool attitudes after interference avoidance are decided by referring to configuration space information for the whole of machining surface. The technique of the previous paper is enhanced, the continuousness of the tool attitude change in the direction of not only tool feed but also pickfeed is considered, and the method for generating the cutter location data for the optimum 5-axis control machining is developed. As a result, the usefulness of the devised CAM system is experimentally found.

Highly efficient manufacture of groove with sharp corner on adjoining surfaces by 6-axis control ultrasonic vibration cutting
FH Japitana; K Morishige; Y Takeuchi
PRECISION ENGINEERING-JOURNAL OF THE INTERNATIONAL SOCIETIES FOR PRECISION ENGINEERING AND NANOTECHNOLOGY, ELSEVIER SCIENCE INC, 29, 4, 431-439, Oct. 2005, Peer-reviwed, Rapid machining means the extreme reduction of the machining lead-time required in completing a product from the blank shape. One of the ways in which machining lead-time could be reduced drastically is by avoiding too many setup changes. This paper presents a new machining method to create a groove with sharp corner on adjoining surfaces in one setup. Grooves with sharp corner (GSC) on adjoined curved or overhanging surfaces are at present impossible to manufacture by conventional machining in one setup or even by the existing numerical control (NC) machining method especially if it is adjacent to the obstruction. The obstruction tends to hamper the flow of machining operation, thereby requiring two or more setups as well as additional expensive fixtures to machine such a product.
In the study, the GSC on adjoined curved or overhanging surfaces will be manufactured by 6-axis control milling using a non-rotational tool with the application of ultrasonic vibrations (USV) in one setup. The study also describes the machining method as well as the development of software for 6-axis control milling and the effect of ultrasonic vibrations in multi-axis machining. Based on the experimental results, the effectiveness of the new manufacturing method as well as the developed CAM software has been experimentally confirmed in the study. (c) 2005 Elsevier Inc.

精密工学会誌1522-1526, The Japan Society for Precision Engineering, 70, 12, 1522-1526, Dec. 2004, Peer-reviwed, The study deals with the automation of polishing process for free-form surfaces by means of an industrial robot. In general, the polishing process has been performed by handwork of skilled workers. Since the polishing environment is extremely inferior and the polishing process is time-consuming and tedious work, the automation of polishing process is strongly desired and the robot systems have been introduced recently. However, the polishing by robots has not necessarily been performed in success. In the study, the polishing path generation is devised to improve the surface quality of workpieces. Thus, the relationship between the surface curvature of workpiece and the contact length of polishing tool is investigated by polishing experiments, which results in the new polishing path generation method. The method is successfully applied to polish an impeller of food and osmetics agitators, which consists of free-form surfaces. As a result, it is found that the new polishing path generation method is effective for polishing automation by robots.

５軸および６軸制御を併用した隅部加工
井沢祐弥; 森重功一; 竹内芳美
精密工学会誌, The Japan Society for Precision Engineering, 70, 8, 1106-1110, Aug. 2004, Peer-reviwed, Simultaneous 6-axis control machining with a non-rotational tool, which can create sharp corner shapes, is not necessarily efficient due to the small depth of cut and the low feed speed. Though the application of simultaneous 5-axis control machining with rotational tools is advantageous in terms of the machining efficiency, the cutting remaining peculiar to the rotational tool take place near the corner part. Therefore, using two machining methods together enables the efficient machining of sharp corner shapes. In the previous paper, we showed the high efficiency of our original machining method of character line using 5-axis and 6-axis control. As the industrial products have various kinds of the corner shape pattern besides the character line, however, the proposed machining method could not cope with all corner patterns. This paper describes the classification of corner shapes at the end of the character line and the generation method of cutting point data for machining of all patterns using 5-axis and 6-axis control.

6-Axis control cutting of overhanging curved grooves by means of non-rotational tool with application of ultrasonic vibrations
FH Japitana; K Morishige; Y Takeuchi
INTERNATIONAL JOURNAL OF MACHINE TOOLS & MANUFACTURE, ELSEVIER SCI LTD, 44, 5, 479-486, Apr. 2004, Peer-reviwed, This paper presents a new machining method that efficiently cuts overhanging curve grooves on wall surfaces without causing a collision between the tool and the workpiece. It also describes the development of software for 6-axis control grooving and the effect of applied ultrasonic vibrations (USV) in cutting overhanging grooves (OHG). In general, rotational tools are used to produce grooves, thus resulting in long circular arc segments at the cutting end points, as well as placing restrictions on the manufacture of grooves with continuous change in curvature, while ensuring that they do not overshoot the side clearance angle of the cutting edge with the groove. The study aims at machining OHGs presently impossible to machine by conventional methods. From the experimental results, it was found that the new machining method, which is 6-axis control cutting using a non-rotational tool with the application of USV, is capable of cutting an OHG on wall surfaces correctly.

5-Axis Control Machining of Complicated Shapes Based on Configuration Space
Koichi Morishige; Tomoyasu Kobata; Yoshimi Takeuchi
Proceedings of the International Conference on Leading Edge Manufacturing in 21st Century (LEM21), The Japan Society of Mechanical Engineers, 2003, 435-440, Nov. 2003, Peer-reviwed, The 5-axis control machining is one of useful methods supporting the reduction of production cost and delivery time. On the other hand, there is a severe problem of interference between the tool and the surrounding objects. In order to solve the tool interference problem, we developed a path generation method using the concept of the configuration space in our previous study. However, the calculation of borderlines of areas in the configuration space is based on the curve interpolation. Thus, the calculation requires excessive time. In the present study, The process is modified by changing the curve interpolation to the linear inter interpolation, which results in shortening the calculation time of the interference-free area and increasing the robustness of calculation. Moreover, the application of curved surface interpolation is proposed, where all tool attitudes are calculated by interpolating some representative attitudes at cutting points. As a result, it is possible to generate the cutter location data by a fewer information in the short calculation time.

森重功一; 井沢祐弥; 竹内芳美
精密工学会誌, The Japan Society for Precision Engineering, 69, 9, 1317-1321, Sep. 2003, Peer-reviwed, 5-axis control machining can create workpieces with complicated shape difficult to machine by 3-axis control. Moreover, 6-axis control machining can cope with workpieces impossible to machine by rotational tools since it can control the direction of non-rotational tool. Though 5-axis control machining which uses rotational tools is advantageous in terms of the machining efficiency, the cutting remainings peculiar to the rotational tool take place at the corner part of workpiece shape. On the other hand, 6-axis control machining can machine the corner part, which cannot be removed with the rotational tool, though it has the low machining efficiency. The use of two machining methods together seems to be very effective to improve the machining efficiency. This research investigates the highly efficient and accurate machining method using 6-axis control machining together with 5-axis control one. The algorithm to generate the cutter location data is developed in consideration of the use of 5-axis and 6-axis control machining, and it is implemented to the integrated CAM software for 5-axis and 6-axis control machining. As a result, it is experimentally found that the system enables the effective and accurate machining.

FH Japitana; K Morishige; Y Takeuchi
INTERNATIONAL JOURNAL OF ADVANCED MANUFACTURING TECHNOLOGY, SPRINGER-VERLAG LONDON LTD, 21, 8, 564-570, 2003, Peer-reviwed, The completion of machining in one setting leads to high accuracy and quality. Since ordinary machining is not capable of fabricating sharp corners, electrical discharge machining (EDM) is used. However, this requires a highly skilled machinist to set up the workpiece to maintain the accuracy of the product since two or more set-ups are involved in this process. In this study, a new manufacturing method for the fabrication of sharp corners is examined experimentally. Six-axis controlled cutting using a bore byte tool with the application of ultrasonic vibration has been applied in this method. Experimental results have shown the applicability of this method in the fabrication of sharp corners.

Ball end mills are in general utilized for the sculptured surface machining. However, it takes much time to finish such complicated surfaces with high accuracy due to the nessesity of a small amount of pick feed. Thus, a new cutting method is proposed to use special cutting tools, called conicoid end mill, for the sculputured surface machining : The study deals with the development of new CAM system with ellipsoid and hyperboloid end mills as well as paraboloid. From the experimental results, it is found that the conicoid end mills have the potential of reducing a machining time remarkably.

精密工学会誌, The Japan Society for Precision Engineering, 67, 1, 142-146, Jan. 2001, Peer-reviwed, The study deals with the development of an integrated main processor of 6-axis control CAM system. The 6-axis control machining, where non-rotational cutting tools are used, has a lot of advantages, compared with the conventional one with rotational cutting tools. The main processors, which have developed till now, can generate CL data corresponding to the kind of 6-axis control machinings such as smooth machining, grooving, character line machining, sharp-edged corner machining, pocket machining, etc. However, it is not convenient to prepare the main processor for each 6-axis control machining method. To solve the problem, the integration of the main processors is intended, where CL data corresponding to specific machining method is automatically generated on the basis of judgment of the shape pattern standing for the kind of 6-axis control machinings. As a result, it was experimentally confirmed that the integrated main processor has the potential to select the suitable 6-axis control machining method and generate the corresponding CL data.

Six-axis control machining with non-rotational tools is a potential method to make a clear character line shape. However, the machining produces not good results due to the low cutting speed. In the study, the vibrational cutting is applied, which is effective in solving the problem such as low cutting speed. The cutter location data must be generated on the basis of the workpiece CAD data, considering the characteristic of the vibrational tool. The effectiveness of the devised method is experimentally confirmed.

曲線補間を用いた5軸制御加工用NCデータの生成法 -5次元非一様 B-spline曲線の適用-
高橋聖次; 森重功一; 竹内芳美
精密工学会誌, The Japan Society for Precision Engineering, 65, 12, 1740-1744, Dec. 1999, Peer-reviwed, The study describes a new NC data generation method for 5-axis control machining, using curved interpolation. In conventional linear interpolation, the amount of NC data tends to increase with increasing the geometrical accuracy of workpiece configurations, which often leads to the reduction in feed speed of machine tools, especially for 5-axis control machining, since a huge amount of NC data can not be accepted in time. On the contrary, as the curved interpolation requires only a few parameters to express workpiece configurations, NC data can be transmitted rapidly, compared with the conventional linear interpolation. The curved interpolation was already applied successfully to 3-axis control machining, however not to 5-axis control one. Thus, in the study, 5-dimensional non-uniform B-spline curve is employed to express 5-axis control curved interpolation NC data in terms of NC data reduction, using 5-axis control collision-free NC data. In a 5-dimensional non-uniform B-spline curve, NC data are significantly compressed by appropriately selecting knot vector on the basis of equally divided curvature area method. From the experimental results of 5-axis control machining, it is confirmed that the curved interpolation has the potential of reducing large amount of NC data without deteriorating the surface roughness and shape accuracy of workpieces.

End mills with arbitrary tool shapes, which are generally difficult to produce, are strongly required in terms of upgrading machining accuracy and efficiency. Thus, our tool grinding CAD/CAM system was already reported, and showed the potentials of producing end mills with arbitralty tool shapes though it was not surtable for practical use. To put them to practical use, the system was improved, taking, account of a grinding method of primary flank, a design of cutting edge shape and five-axis NC data generation. As a result, the system allows to produce practical end mills with arbitrary tool shapes. In addition, it is found that end mills fabricated by, the, system have enough shape accuracy, compared with commercially available ones.

Tool path generation using C-space for 5-axis control machining
K Morishige; Y Takeuchi; K Kase
JOURNAL OF MANUFACTURING SCIENCE AND ENGINEERING-TRANSACTIONS OF THE ASME, ASME-AMER SOC MECHANICAL ENG, 121, 1, 144-149, Feb. 1999, Peer-reviwed, The paper deals with the method of tool path generation for 5-axis control machining rising a ball end mill. 5-axis control machining has been used for aircraft parts as well as for complicated shapes such as mold and dies. However, most of the present CAM systems for 5-axis control machining have limited functions in terms of tool collision, workpiece shapes and machining methods. For that reason, in many cases the optimal cutter location (CL) data cannot be obtained or considerable ti,ne is consumed. To solve this problem, we applied a 3-dimensional configuration space (C-Space) and showed the relationship between all tool positions and postures and the existence of tool collision. The method of tool path generation devised in the study enables users to generate CL data reflecting their own machining strategy such as smooth change in tool posture and the state of machining without considering the gouging. The validity of this method was experimentally confirmed by successfully milling an impeller without tool collision occurring.

In general, ball end mills are utilized for the sculptured surface machining. However, it takes much time to finish such complicated surfaces with high accuracy due to the necessity of small amount of pick feed, which causes the reduction in machining efficiency. Thus, special cutting tools called conicoid end mill were devised to meet the requirement of relatively large amount of pickfeed. The adequate selection of tool attitude allows a large amount of pick feed, and yields good surface quality in surface finishing.

5-axis control rough cutting of an impeller with efficiency and accuracy
K Morishige; Y Takeuchi
1997 IEEE INTERNATIONAL CONFERENCE ON ROBOTICS AND AUTOMATION - PROCEEDINGS, VOLS 1-4, I E E E, 1241-1246, 1997, This study deals with how to generate 5-axis control rough cutting NC data. The 5-axis control machining offers the potential of efficient and accurate machining. However present CAM systems for 5-axis control are lacking in generality and functions for the tool path generation. Although the rough cutting is the most important process influencing the machining time and the condition in the following finishing process, a lot of difficulties arise to perform 5-axis control rough cutting. Especially, the collision between a tool and surrounding objects is still a severe problem. This paper suggests the collision-free tool path generation for 5-axis control rough cutting, taking account of efficiency and accuracy. The devised method allows an impeller-like shape to be actually milled with efficiency and accuracy. As a result, the validity of the method is experimentally confirmed.

Collision-free tool path generation using 5-dimensional C-space for 5-axis control machining
K Morishige; K Kase; Y Takeuchi
INTERNATIONAL JOURNAL OF ADVANCED MANUFACTURING TECHNOLOGY, SPRINGER-VERLAG LONDON LTD, 13, 6, 393-400, 1997, Peer-reviwed, This study deals with the method of collision avoidance in the automatic tool path generation for 5-axis control machining. Five-axis NC machining offers the potential for efficient and accurate machining, but collisions between the tool and surrounding objects are still a severe problem. The method devised in this study avoids collision by producing the direction of collision avoidance, based on the 2-dimensional configuration space (C-space) defined by two parameters which deter-mine the tool attitude. This method allows a test workpiece with overhanging parts to be milled without collisions. As a result, the validity of the method has been experimentally confirmed.

D01 Development of operation interface for multi-axis controlled machine tool using Haptic Device : Approximation of tool path by straight line and curves
SASAKI Shunya; MORISHIGE Koichi
Because the demand of multi-axis controlled machine tool is increasing recently, the new interface functions for the machine tool are needed, which allow us the institutive, safe and accurate operation. The final purpose of our research is development of interface which operates a multi-axis controlled machine tool directly by Haptic Device. However, in the developed interface, operator's tremor disturbed tool path, and disorder of tool path deteriorated the appearance of machined surface. This report introduces the interface function that reduces disorder of tool path by approximating tool path as sets of curves and straight lines. The most difficult part in the approximation is the determination of segmentation point. In this research, segmentation points are determined by corner points of tool path and speed at the tip of device. As the result, we confirmed the decrease in disorder of tool path and the improvement of appearance of machined surface., The Japan Society of Mechanical Engineers, 14 Nov. 2014, The ...

G130012 Polishing Process Automation by Industrial Robot : Visual Inspection Based on Statistical Pattern Recognition
OKAMOTO Ken; MORISHIGE Koichi
This study deals with automation of polishing process by using an industrial robot. In polishing process, full automation of polishing operation has not been achieved due to the difficulty in visual inspection. Judgment of whether polishing is sufficient or not has been performed by skilled workers. In this study, the polishing after milling process is targeted. In the previous report, the generation of robot program for polishing operation based on CAD data was already proposed. Focusing on the periodicity of cutter mark patterns on milling surface, we proposed an automatic judgment of polished surface quality based on the image processing which uses Discrete Fourier Transformation. In order to capture images of polished surface, a CCD camera was mounted at 6-axis controlled robot hand. However, the image processing method proposed in previous report could not judge the curved cutter mark patterns because the periodicity of those patterns is not uniform. The objective of this report is the development of automatic judgment method for non-periodic cutter mark patterns. We developed judgment method which uses pattern recognition as a mean to judge existence or not of cutter marks. As a result, the developed system allows the automatic polishing that includes the surface quality judgment., The Japan Society of Mechanical Engineers, 09 Sep. 2012, Mechanical Engineering Congress, Japan, 2012, "G130012-1"-"G130012-4", Japanese, 110009994365, AA12588255

Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, The University of Electro-Communications, Grant-in-Aid for Scientific Research (B), The study is concerned with the e^3-PLM (Product Lifecycle Management). The e^3-PLM is a kind of PLMs, and it is an "ecology-oriented", "enduser-oriented", and "electronic ICT (Information Communication Technology) based system. In the PLM the importance of end-users is insisted and product use history data are utilized to realize environment friendly product management. The obtained results are follows. (1) The structure of e^3-database for the PLM is designed. The database consists of a global database and local databases. The global database contains product design information, product handling information, product use history, and communication information, and it can be accessed by manufacturer, end-users, and recyclers. On the other hand, the local database is maintained by each sector and it contains internal information of the sector such as facility information, process plans, sales plans, etc. (2) For the important scenes in product lifecycle, the value of information in e^3-database is evaluated and the methods to utilize the information are developed. (a) The framework of PLM is developed and products management policies for products maintenance, renewal, and replacement are analyzed. Especially, environmental impacts related with products refurbishment are analyzed in detail. (b) A database structure is developed to utilize product use history data. Then, an algorithm is developed to determine the effective handling method of post-consumer products. (c) Processing and environment related attributes are added to products 3D-CAD models, and a design system is developed so that the environmental impacts of product over its lifecycle can be reduced at the product design stage. (d) Operation planning is a vital activity in manufacturing, remanufacturing, and recycling operations. Then, an operation planning support system using the standardized machining information is developed. (e) A method to calculate the economic value of the information in e^3-database is developed. Further investment decision problem with emissions trading is analyzed., 17310095

Creation of Ultraprecision Micro Parts with High Aspect Ratio and Complex Shape and its Application
TAKEUCHI Yoshimi; SAWADA Kiyoshi; ISHIDA Tohru; MORISHIGE Koichi
Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Grant-in-Aid for Scientific Research (B), The study deals with the creation method of ultraprecision micro parts with high aspect ratio and complex shape, i.e. tall, small and complex shape, by making use of a multi-axis control ultraprecision machining center. The shape with high aspect ratio is usually difficult to create. The possibility of creating such a shape may lead to the application to new fields. In the previous year, the fundamental shape creation technology such as micro trapezoid groove, cylinder and prismatic parts of 1 mm in length with aspect ratio of 40, etc. was established by use of various kinds of diamond tools. This year, the following shapes were created; (1) micro pin array consisting of several cylinders and prismatic parts with high aspect ratio, (2) mirror segments array as an optical system for the next generation stepper and (3) micro Buddha head with complex shape. With regard to each item, the study is summarized as follows: (1) Micro pin array with 9 needles could be machined with a rotational diamond tool, based on the tool path generated by the way of not making contact any more with already machined portions. The metal molding technology is required to produce such a shape since it takes much time to create it. Thus, the electro plating was tried for molding, however the uniform electro plating was difficult to achieve. (2) Mirror segments array, whose surface roughness is 1 nm, consists of a series of 1mm* 15mm segment being cut from different positions of the sphere of 660 mm in radius. With 5-axis control machining, the segments of about 660mm in radius were machined, however the surface roughness was 10 nm. Farther improvement is required. (3) Based on the shape data of Buddha bead, 5-axis control machining of Buddha head of about 3 mm in diameter was carried out, taking account of tool collision. The shape was successfully completed, however has overcut parts on the surface due to the difficulty of tool setting., 13555033

Accurate Machining of Difficult-to-Machine Shapes by Means of 6-Axis Control Vibrfational Cutting
TAKEUCHI Yoshimi; ISHIDA Tohru; MORISOIGE Koichi
Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, The University of Electro-Communications, Grant-in-Aid for Scientific Research (B), The demand for efficient and accurate machine tools and machining technology is rapidly increasing in recent years. The intensive manufacturing technology capable of the whole machining at one setup allows machine tools to realize the efficient and accurate machining. The study proposes a new machining method of combining sophisticated. 5-axis control machining with 6-axis control, one using non-rotational cutting tools. However, the cutting speed of 6-axis control machining is low, which causes the deterioration of machined surface quality. Thus, the ultrasonic vibrational cutting was employed to solve the problem. The study is summarized as follows : 1. The-main processor to generate cutter path (CL) data for 6-axis control machining, based on workpiece shapes defined by 3D-CAD system, was developed, especially for character line machining and asymmetric grooving, taking account of collision avoidance between tool and workpiece. 2. Cutting experiments by use of a vibration tool were carried out on a 6-axis control machining center with NC data converted from CL data by use of our own post processor. As a result, the workpiece with fine surface quality can be obtained. 3. A part of the integrated multi-axis control CAM system was achieved to perform the efficient machining ,by unifying the effective 5-axis control CAM system and the 6-axis control one developed in the study., 12450057

Direct Bonding of Small Parts by Means of Ultraprecision Microgrooving Technology
TAKEUCHI Yoshimi; SAWADA Kiyoshi; MORISHIGE Koichi
Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, The University of Electro-Communications, Grant-in-Aid for Scientific Research (B)., The study proposes a new method of bonding two small parts without the use of any adhesive by making use of ultraprecision V-shaped microgrooves on the surfaces of each part. These V-shaped microgrooves allow small parts to be bonded together with high positioning accuracy due to a wedge effect and an adhesion phenomenon between the mating surfaces. Ultraprecision V-shaped microgrooves are created by using an ultraprecision machining center having 1 nm positioning resolution and a diamond milling cutter. The study is summarized as follows : 1. It is found that the bonding strength in general increases with decreasing wedge angle. The effect of the wedge length on bonding strength though varies with the wedge angle where the strength increases with increasing length for wedge angles greater than 8 degrees but increases with decreasing length for wedge angles less than 8 degrees. 2. These V-shaped microgrooves, whose depth and angle are 20 μm and 13.5 degree respectively, allow small parts to be tightly bonded together with high positioning accuracy due to a wedge effect and an adhesion phenomenon between two mating surfaces. 3. Small parts of 4 mm * 4 mm * 4 mm that have V-shaped microgrooves in two direction could be tightly bonded with 0.380 μm positioning accuracy. 4. The new method has a possibility to bond different materials each other. Two small parts with V-shaped microgrooves that are made of oxygen-free copper and aluminum are subjected to bonding test. As a result, the proposed bonding method is found to be effective to connect small parts accurately. 5. It is experimentally found that the microgrooving technology is also applicable to manufacture various Fresnel lenses and optical elements., 11555042
