| Summary: | 碩士 === 正修科技大學 === 機電工程研究所 === 96 === The spiral bevel gears drives have the characteristics of high transmission efficiency and low level of noise/vibration when compared with other types of gear mechanism. It has been increasingly popular in the industry and transmissions of helicopters, automobiles, etc.
In this thesis, the method for design and machining of the spiral bevel gears are established according to the differential geometry and homogeneous coordinate transformation. The surface and solid model are built by CAD/CAM software. The interference-free toolpath and the cutter location of rough, semi-finish and finish machining for multi-axis NC machining are generated. The post-processor of five-axis machine tool with table tilting type is developed according to the kinematics. The post-processor converts the cutter location file into the NC code. The cutting simulations with solid model are performed to verify the toolpaths.
