Intelligent generation method and device for numerical control machining program based on multi-modal semantic understanding

Abstract

The present application relates to the technical field of computer aided manufacturing, and discloses a kind of method and device for the intelligent generation of numerical control machining program based on multi-modal semantic understanding, to solve the technical problems of high artificial dependency and poor general effect of the generation method of numerical control machining program in prior art. Including: obtaining drawing file containing multi-modal processing information, pre-processing and format conversion are carried out on the drawing file, and the standardized input data that can be parsed is obtained;Call multi-modal recognition algorithm, identify and extract target information;Combined with the semantic dictionary of mechanical processing, call multi-modal semantic understanding model to obtain processing manufacturing information according to target information, and convert the processing manufacturing information into a structured form to build a PMI data model;Based on the process constraint relationship of PMI data model, and calling intelligent planning model to generate process planning, select tool, set tool parameters, and generate machining path;Call code generation model to convert machining path into numerical control machining program.
