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± 10 μm的加工精度 Several important problems in the design of CNC system of CNC convex lathe machining with oval piston are discussed emphatically. It is pointed out that the piston machining process must be considered from two aspects of kinematics and dynamics. Based on the above principles, this paper successfully designs the CNC system of the piston machining CNC lathe. The experimental results show that the machining of the piston can achieve high speed and ± 10 μm machining accuracy
