摘　　要：重点探讨了中凸变椭圆活塞加工数控车床数控系统设计中的几个重要问题 ,指出 ,必须从运动学和动力学两个方面考虑活塞加工过程。本文依据上述原则成功地设计了活塞加工数控车床的数控系统 ,实验结果表明 ,对活塞加工可以达到较高转速和± 10In this paper,some key issues of machining pistons with convex contour and vari elliptical cross section are discussed.It is pointed that kinematics and dynamics should be considered contemporaneously in the designing process.By these principles,the NC system of piston machining lathe is designed.The testing results show that high rotating speed as well as high accuracy of ±10μm can be reached.
