Abstract:

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.

Key words: high-speed machining, steep surface, spiral cutting, tool-path optimization

摘要：

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。
