摘　　要：为提高外壳凸模的加工质量和生产效率,在分析零件特点的基础上,通过精细划分切削区域,采用不同的加工方式高效的切削工件,减少加工时间;在精加工先加工底面后加工侧面的基础上,提出了底-侧面结合处增加0.01~0.02mm让刀设置,使刀具底刃和侧刃不同时参与切削,在提高零件表面质量的同时还能保护刀具。最后以UG NX9.0为软件平台,合理设置各项加工参数,生成了外壳凸模刀具路径,利用仿真加工,检验刀轨的可靠性,实践结果表明：通过此种工艺加工的零件,其表面质量和加工效率得到有效提高。为工程中同类零件的数控加工提供借鉴。To improve the machining quality and production efficiency,NC machining of shell punch was researched by analysis its characteristics. The machining process was optimized by considering processing order and controling the machining allowance. the bottom side of the junction increased 0. 01-0. 02 mm cutter relieving is arranged based on the principle of first processing the bottom and after processing the side,this will lead the cutter bottom edge and side edge not involved in cutting at the same time,so the tool is protected and the surface quality of parts can improve at the same time. At last,the part tooling path was generated through set the reasonable processing parameters,the tooling path was tested by simulation based on UG NX9. 0,and the part is machined smoothly. The results showthat the surface quality and processing efficiency can be improved effectively. It provides reference for the process of this kind of parts.
