子程序常用于加工几何形状完全相同或相似的加工轨迹,本文主要分析了数控车子程序的编制格式,子程序编制时的相关尺寸计算及处理方法,并以加工实例进一步阐明了子程序的编制及使用技巧。 Subroutines are commonly used to process the same or similar machining trajectories. This paper mainly analyzes the programming format of numerical control car subroutines, the calculation and processing of the relevant dimensions in the subroutine programming, and further illustrates the establishment of subroutines skills.
