摘要
空间螺旋槽通常采用CAD/CAM软件自动编程方式实现,过程繁琐且零件造型复杂。通过分析第四轴加工坐标转换时,直线Y坐标值转化为回转坐标值A的数学推导过程,以此编写了空间螺旋槽的四轴数控加工宏程序,通过步距变量控制加工误差,经VERICUT仿真验证及实际机床加工,程序运行结果正确。通过赋值宏变量(螺旋槽半径、直线长度等),可以实现不同大小的圆柱面上加工多个不同尺寸大小的沟槽。
Machining of the spatial spiral groove is usually completed with CAD / CAM automatic programming,which is complex and cumbersome. In this paper,we analyzed the process of converting Y coordinate values into rotary coordinate values when doing the fourth axis coordinate transformation. On this basis,we wrote the macro program for the four-axis NC machining of the spatial spiral groove. With machining errors controlled through step pitch variables,and VERICUT simulation and actual machining carried out,the results of the program were proved correct. Through assignment of the macro variables（ spiral groove radius,line length,etc.）,the machining of grooves of different sizes on columns of different sizes could be achieved.
