圆弧面蜗杆数控车削加工的宏程序实现

摘要

ARC-surface worm can not use worm screw turning as a special type of worm, so it usually requires a dedicated machine. About macro function of CNC lathe, arc can be converted into small segments and imposed thread cutting on small segments. Using macro program cycle control can be done turning for arc-surface worm. Practice has proven that this method is easy to control and has strong adaptability, it provides a new set of ideas for the arc-surface worm process implementation.%圆弧面蜗杆作为一种特殊的蜗杆类型,无法用一般蜗杆螺纹的车削方式,通常需要专用机床加工.对具有宏指令功能的数控车床而言,可将圆弧转化为小线段,然后对小线段实施螺纹切削,采用宏程序循环控制即可实现圆弧面蜗杆的车削加工.实践证明,该方法控制方便、适应性强,为圆弧面蜗杆加工的实现提供了一种新的思路.
