运用宏程序车削大导程非标准梯形螺纹的方法

The Measure of Using Macro Programs Turning Non-Standard Trapezoidal Thread

大导程非标准梯形螺纹的加工是数控车削的一个难点。由于导程大走刀速度快,切削深度较深,切削抗力较大,而且精度要求较高,如果用简单的指令很难车削大导程的非标准梯形螺纹。介绍一种实用、高效的运用宏程序在数控车床加工非标准梯形螺纹的车削方法。

Large non-standard trapezoidal thread lead CNC Turning process is a difficult issue.As lead is large and take the knife speed,depth of cut deep,cut the larger resistance,and high precision,with simple instructions is difficult if turning a large non-standard trapezoidal thread lead.This paper describes a practical and efficient uses of macro programs in the CNC lathe for turning non-standard method of trapezoidal thread.
