基于振动技术的内燃机活塞复杂裙面加工方法研究

基于分解设计、叠加成型的思想，研究了非圆截面车削方法和非线性型线加工方法，提出了结合偏心振动技术和数控单元的中凸变椭圆裙面加工原理，本方法可实现普通车床的数控改造，成为活塞裙面加工专用数控车床，经济可靠，容易实现．

Complex Profile of Engine Piston Skirt Produced by a Technology with Vibration

Engine piston skirt with a mid convex contour and ellipticity varying cross sections is difficult to machine. For machining non circular sections with complex contour, a new scheme is developed that integrates bias vibration and stepmotor. A numerical control system can thus be developed on the engine lathe to ease and economize the process of making pistion skirts.
