基于宏变量的曲面特殊螺纹数控车削工艺研究

Based on Macro Variable Special Thread Surface NC Turning Technology Research

首先介绍了宏变量的功用和特点,接着从曲面特殊螺纹加工的刀具选择、夹具选择、切削用量选择等方面详细分析了螺纹加工工艺,最后给出了利用宏变量和螺纹加工基本指令组合编程加工的椭圆面和圆弧面特殊螺纹加工实例。

First introduces the function and characteristics of macro variables,and then from the surface of special screw thread processing of the choice of cutting tool,fixture,cutting parameter selection are analyzed in detail in aspects of thread processing technology,finally was given by using the macro program and thread processing basic instruction programming ellipsoid and circular arc surface of the special thread machining instances.
