Graphical interactive auxiliary numerical control programming method and software system

The invention relates to the technical field of numerical control programming, and discloses a graphical interactive auxiliary numerical control programming method and software system. The method comprises the steps of numerical control machining program file input, program file editing, file merging, program gang tool optimization and program output; wherein the program file editing step comprises two sub-steps of single file confirmation and multi-file mixed makeup; the file merging step refers to merging a plurality of numerical control program files into a numerical control file; the program gang tool optimization step refers to automatically adjusting program segment codes containing the same tool together; and in the program output step, the numerical control machining program file subjected to gang tool optimization is output and stored in a storage medium to be called by the numerical control machine tool during use. According to the invention, post-processing can be conveniently carried out on the nu
