用宏程序进行编程,可以轻松实现工件上特殊结构的加工,如变螺距螺纹、大螺距螺纹等。本文介绍用宏程序编程,实现左右斜进车削大螺距螺纹的加工,并把它制作成一子程序,在主程序中,只要编入相应的调用指令就能实现各种不同螺纹的加工,从而节省编程时间,提高生产效率。 Programming with a macro program, you can easily achieve the workpiece on the special structure of processing, such as variable pitch thread, large pitch thread. This article describes the use of macro programming to achieve the left and right bevel turning large pitch thread machining and make it into a subroutine in the main program, as long as the corresponding call instruction can be programmed to achieve a variety of different threads, thus saving Programming time, improve production efficiency.
