Part machining process file generation method and device

Abstract

The invention discloses a part machining process file generation method and a part machining process file generation device, and belongs to the field of three-dimensional process design. The method comprises the steps that a part model and a workblank model are obtained, and the part model and the workblank model both have size labeling information; determining structural characteristics accordingto the part model, wherein the structural characteristics comprise at least one of a plane, a curved surface, a hole, a groove, a chamfer, a fillet and a thread; determining a process chain for processing each structural feature from a process knowledge base, wherein the process chain comprises a plurality of processing steps for processing the structural features and orderly arranging the structural features; determining a processing sequence of each structural feature; generating a plurality of models after each processing step is completed according to the blank model, the processing sequence and the determined process chain of each structural feature; and generating a three-dimensional process file according to the plurality of models, wherein the three-dimensional process file comprises the plurality of models arranged according to the processing progress. Compared with a traditional process card, the three-dimensional process file is more visual, the generation mode is simple, the workload is small, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of three-dimensional process design, in particular to a method and device for generating machining process files of parts. Background technique [0002] As a bridge connecting product design and manufacturing, process design plays a vital role in product quality. [0003] Before actual machining, process design is usually required to obtain machining process documents, such as traditional paper two-dimensional process cards. After the process card is sent to the workshop, the workshop can process it according to the information given by the process card, and finally get the processed parts. [0004] Since a part usually needs to be processed many times from the blank to the finished product, it is necessary to design a large number of two-dimensional process cards, which is low in efficiency and heavy in workload. Contents of the invention [0005] The embodiments of the present invention provide a method and devi...
