Multi-level structured numerical control process model construction method based on dynamic processing characteristics

The invention relates to a multi-level structured numerical control process model construction method based on dynamic processing characteristics. The method comprises the steps of determining relevance between processing layers of a sub-processing area and each processing operation by calculating an actual effective processing area of each processing operation on each processing layer of a pre-associated sub-processing area; according to the relevance between the processing layer of the sub-processing area and the processing operation, associating the processing layer of the sub-processing area with the processing operation; capturing a process design intention of associated processing operation of a processing layer of the sub-processing area, and obtaining a multi-level structured numerical control process model for realizing dynamic processing feature recognition by constructing a process situation merging and splitting relationship of the sub-processing area; the invention is used for generating a macros
