摘　　要：活塞是汽车发动机的核心部件,中凸变椭圆活塞的动力性能和润滑性能优于普通活塞,但活塞裙部廓形复杂,数控编程和加工困难。文章提出一种活塞曲面插补计算方法和数控车床进给运动控制技术,可实现对中凸变椭圆活塞的高效加工。The piston is the core component of a car engine. Dynamic performance and lubricating prop- erties of middle-convex and varying ellipse piston is superior to the ordinary piston, however, because of the complex piston skirt profile, the CNC programming and machining are difficult. In this paper, a piston surface interpolation calculation method and CNC lathes feed motion control technology is presented, which can achieve the efficient processing of middle-convex and varying ellipse piston.
