Description

Technical Field

[0001] This invention relates to the field of mold base processing technology, and more specifically, to a method and system for batch processing of non-standard mold bases. Background Technology

[0002] The machining of mold frame plates is mostly done by generating machining instructions through software programming. The machining center then performs machining according to these instructions, and the order of the machining instructions is determined by the programming order. Currently, workpiece programming is done on a single workpiece in one coordinate system or on multiple identical workpieces in multiple coordinate systems. It is not possible to program multiple different workpieces in multiple coordinate systems.

[0003] Machining centers can only process one sheet metal at a time or multiple identical workpieces simultaneously. For multiple different sheet metals, different processing contents and requirements require different cutting tools. When one tool (e.g., tool No. 1) is used up, another tool (e.g., tool No. 2) needs to be used. When tool No. 1 is needed again, it needs to be used again, resulting in repeated tool changes. Each tool change requires tool loading, tool setting, parameter verification, etc., which is time-consuming and has low processing efficiency. Summary of the Invention
