在编程工作中,我们经常把能完成某一功能的一系列指令像子程序那样存入存储器,用一个总指令来代表它们,使用时只需给出这个总指令就能执行其功能,所存入的这一系列指令称作用户宏程序本体,简称宏程序。这个总指令称作用户宏程序调用指令。在编程时,编程员只要记住宏指令而不必记住宏程序。用宏程序指令加工有规律的零件,在数控加工中应用非常的广泛,如何在加工过程中按照合理的工艺编制出正确高效的加工程序是非常重要的。
In programming, we often put a series of instructions that can accomplish a certain function into memory as a subroutine, and they are represented by a general instruction. Only the general instruction can be used to perform its functions. Into this series of instructions called the user macro program ontology, referred to as macro program. This general instruction is called user macro call instruction. When programming, the programmer only needs to remember the macro without having to remember the macro. It is very important to process the regular parts with the macro program instructions. It is very widely used in the NC machining. It is very important that how to process the correct and efficient machining programs according to the reasonable process in the process.
