Accuracy Measurement and Evaluation of Straight Bevel Gear Manufactured by End Mill Using CNC Milling Machine
Journal of Mechanical Design Transactions of the ASME, 2009Co-Authors: Kazumasa Kawasaki, Kazuyoshi ShinmaAbstract:Straight bevel Gears are usually manufactured with various machines and systems, and the tooth profiles are produced by grinding or machining by means of a tool with many cutting edges. In recent years, the straight bevel Gear has been manufactured by an end mill using a computer numerical control (CNC) milling machine because the use of the auxiliary apparatus, special cutters, and special machine tools is not needed. Using this method, the Gear manufacturing with high Accuracy is an important problem. In this paper, the coordinate measurement of the straight bevel Gear manufactured in this method is performed and the Gear Accuracy is evaluated. The tooth profiles of the straight bevel Gear generated by a quasi-complementary crown Gear instead of a conventional complementary crown Gear are introduced. For this study, the tooth profiles of the straight bevel Gear were modeled using a 3D computer-aided design system and the Gear was manufactured by an end mill using a CNC milling machine based on a computeraided manufacturing process. Afterward, the coordinates of many points on the Gear tooth surfaces were measured at random using a coordinate measuring machine. This coordinate measurement provides the information about the factors related to the Gear Accuracy such as pressure angle, tooth angle error, workpiece setting angle, apex to back, and so on. Therefore, the values of the above factors were estimated and were compared with the theoretical ones, respectively. Copyright © 2009 by ASME.

Cutting Performance in Machining of Large-Sized Spiral Bevel Gears Using Multi-Axis Control and Multi-Tasking Machine Tool
Applied Mechanics and Materials, 2014Co-Authors: Kazumasa Kawasaki, Isamu TsujiAbstract:Large-sized spiral bevel Gears are usually manufactured based on a cyclo-palloid system and have equi-depth teeth as well as a face hobbing system by a continuous cutting procedure using a special generator. It has been possible to machine the complicated shape because of the development of a multi-axis control and multi-tasking machine tool.The manufacturing method of the Gears has been proposed using this development process. In this method, the spiral bevel Gears are modeled based on a CAD system and are machined based on a CAM system. In this paper, the cutting performance in machining of the large-sized spiral bevel Gears using the multi-axis control and multi-tasking machine toolis investigated. As a result, the relationship between the tool life of end mill and Gear Accuracy were made clear. The surface roughness and tool mark of the machined Gears were compared with those using the special generator.

Gear Inspection and Error Compensation Control Method Based on Coordinate Measuring Machine*
2019 14th IEEE Conference on Industrial Electronics and Applications (ICIEA), 2019Co-Authors: Zhaojun Meng, Lianzhi Jiang, Xuejun HeAbstract:According to the principle and method of face Gear processing, using the differential geometry and meshing principle, get the theory surface equation of face Gear tooth. For a prototype of Gear machining test, a large number of data points of the tooth surface obtained using Croma 10218 type coordinate measuring machine(CMM). By fitting these data points with NURBS surface, the 3d parametric model of real tooth surface is established. The feature points on the fitting surface are compared with the original points, the error is analyzed and the error compensation is made. Finally, Re-comparison again after error compensation. The results show that the tooth profile deviation between the NURBS fitting surface and the actual tooth surface is within the allowable range, indicating that the technical method based on the CMM surface Gear detection and NURBS surface fitting error compensation control technology method is strict logic and clear thinking, and has a good feasibility in the surface Gear Accuracy evaluation.
