用户宏程序在数控加工中有着广泛的应用。由于宏程序中使用了各种变量、运算指令和控制指令,从而大大简化了程序,而且还可以通过设置不同的变量,实现对简单立体型面的手工编程加工,并通过改变参数,实现粗、精加工,达到所要求的加工精度。该文通过一个圆台的加工较为详细地讲述了宏程序的原理及应用技巧,有兴趣的读者不妨一读。
User macro program has a wide range of applications in CNC machining. Because the macro program uses a variety of variables, arithmetic instructions and control instructions, which greatly simplifies the program, but also can be set by different variables, to achieve simple three-dimensional surface of the manual programming, and by changing the parameters, to achieve coarse, Finishing, to the required processing accuracy. This paper describes the principle and application of macros in more detail through the processing of a round table. Interested readers may wish to read it first.
