摘要 :针对虚拟车削加工中振动问题的处理,对外圆车削加工的理论粗糙度模型进行了修正。通过预测工件与刀具的相对位移,实现了对加工工件的表面形貌的估算。通过对表面形貌的仿真,提高了虚拟车削软件的应用性。

YAN G Guozhe 　WAN G Wei 　GON G Yadong 　WAN G Wanshan

Abstract: The paper aim at the problem of vibration in virtual turning operations amended the theoretic model of the toughness in cylinder turning. By the forecast of the displacement of the tools and part , estimated the surface appearance of the parts machined. By this means , high quality of simulation of NC turning is attained.
Key words :physical simulation ; machining process modeling ; surface roughness
