面向零件陡峭面加工的刀路优化问题研究

针对目前数控加工过程中零件陡峭面螺旋切削加工方式的局限,在对高速加工（HSM）切削路径进行研究的基础上,借鉴手工编程的优点,通过整合辅助螺旋线和平面轮廓线的投影对计算机辅助制造(CAM)过程进行优化,提出一种新型复合式螺旋切削刀路,从而扩展了先进螺旋切削方式在高速加工中的应用范围。VERICUT软件模拟和实际加工的结果表明，新型刀路能够满足陡峭面和平面并存零件高速加工路径的要求。

Study on Machining Tool-path Optimization for Part Steep Surfaces

Against the limitations of machining method that were currently used for spiral cutting of steep surfaces in CNC machining process, based on study of tool-path of the high-speed machining, drawing on the advantages of manual programming, through the projection and the integration of auxiliary lines, a process of computer-aided manufacturing(CAM) was optimized. This paper proposed a new kind of hybrid spiral tool-path that expanded the application area of the advanced spiral cutting approach in high speed machining. The simulations on VERICUT and machining practices show that the new tool-path is able to meet requirements of high-speed machining for parts with both steep surfaces and flat planes.
