摘　　要：在模具制造过程中经常遇到薄壁零件的加工,而加工过程中薄壁件的变形问题以及加工效率的问题一直困扰着工程技术人员。笔者针对薄壁结构电极零件切削过程中的变形问题展开研究。在高速机床上试验加工一个薄壁铜电极,从工件装夹、切削参数选用、工序安排、走刀路线等方面展开研究,控制产品变形量达到最小。试验件产生的最大变形量经实测仅为0.014mm,变形极小,表面粗糙度值最大处仅为0.63μm,完全能满足产品要求,而且,加工效率明显高于普通切削加工。We mainly studied the machining deformations of thin-structure components in end milling. In milling a thin-walled electrode on a high-speed machine, the process is studied concerning the clamps, the cutting parameter, the working procedure, the cutting tool path etc. The deformation of the part is controlled to be minimum. The maximum deformation is only 0. 014 mm, the surface roughness value is only 0.63μm. It can meet product requirements, and the processing efficiency is significantly higher than ordinary machining.
