Description

technical field [0001] The invention relates to the technical field of stamping die programming, in particular to a stamping die 2.5D automatic programming method based on data intelligent identification technology. Background technique [0002] The structure of the stamping die is composed of an upper die base, a lower die base, a pressing material core and corresponding auxiliary inserts, sliders and standard parts. There are many features and types of structural surfaces, and the size and position parameters are different. The types of features are: insert mounting surface, screw holes, positioning key mounting grooves, guide holes, guide sliding surfaces, etc. The structure is as follows: Figure 1-2 shown. [0003] CNC programming is the most important part of CNC machining. The efficiency and quality of programming are of great significance to the manufacturing cycle and processing quality. At present, the 2.5D structural surface is programmed by the programming engin...
