Research About The Macro Program Based On Star Huazhong Cnc System

With CNC technology and the rapid development of computer-aided manufacturing software, in the NC programming, manual programming are increasingly being replaced by computer automatically programmed, so that slowly everyone ignored the macro program for manual programming, especially the importance of a Macro programs can be easily prepared three-dimensional surface processing procedures, but procedures are very simple, common good, for the same shape, different sizes of parts, just call the macro program can be assigned different values. This article briefly analyzes the basic theories of macro program knowledge and application of technical rules from the macro programs start with the essence of macro program analysis, and macro programming subroutine calls, milling to achieve dynamic knife fill the space trajectory macro programming be discussed and to be specifically addressed in the form of examples, finally, on the macro expansion of the secondary development of technology has done a preliminary study.
