用户宏指令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,大大简化了程序,而且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、精加工和达到所要求的加工精度。运用用户宏指令对HNC-21T数控系统进行深孔加工参数化设计,用户只要输人孔深等参数,便可方便地在HNC-21T数控车中进行深孔加工。真正实现了深孔钻程序的模块化设计。
User macro instructions in CNC machining has a wide range of applications. Because the macro program uses a variety of variables, computing instructions and control instructions, greatly simplifying the program, but also by setting different variables, to achieve simple three-dimensional surface of the manual programming, and by changing the parameters, to achieve rough, finishing And achieve the required machining accuracy. HNC-21T numerical control system is deeply parametric designed by user macros. Users only need to input the parameters such as deep hole and so on, so that the deep hole can be easily processed in the HNC-21T CNC car. Truly realize the deep hole drilling program modular design.
