摘　　要：介绍了中凸变椭圆活塞异形外圆车削加工技术的发展,并对其椭圆型面的车削加工原理作了详细分析。通过分析得出车床对进给系统的要求和采用"软靠模"数控车削加工的必要性,并设计了一种采用直线电动机的进给机构,以实现该类零件的加工,使加工精度得到显著改善,同时,缩短了加工时间,降低了生产成本。The paper introduces the irregular surface turning technology for middle-bulged varying ellipse pistons, analyzes the principle of machining non-circular sections, such as ellipse, obtains the demand for feed system and the necessity of ＂soft explorator＂ and presents a newly developed lathe, in which linear motor driven system is used as its feed system. The cutting accuracy is greatly improved, machining time and production costs are greatly reduced.
