Abstract

The invention discloses an intelligent programming method comprising the following steps: S1, extracting part feature information based on an STEP file; S2, expressing part process features and establishing a classification basis; S3, analyzing the similarity between machining processes; S4, defining process features; S5, establishing process feature identification rules based on combinative reasoning; and S6, generating a machining process according to the process features, and generating an NC code according to the setting of post-processing. According to the invention, the process features of a part model are identified by analyzing an STEP neutral file of the part model and the machining process of a part-like model and making use of feature identification rules based on sound reasoning, and a reusable machining process library is established based on the macro instruction function of Powermill and is combined with the identified process features. Therefore, a numerical-control automatic programming method with a learning function based on process feature recognition is realized, and seamless connection between a feature identification system and a CAM system is realized.

Description

technical field [0001] The invention relates to the technical field of numerical control machining, in particular to an intelligent programming method. Background technique [0002] With the development of CNC machining technology, the mold industry is also developing rapidly. As we all know, EDM is an effective way to shorten the mold manufacturing cycle. As an indispensable part of EDM, electrode is the main factor determining the quality of EDM, so electrode processing has become an important part of CNC machining. The programming process of electrode processing is complicated and error-prone, so how to effectively improve the quality and efficiency of electrode processing has become an urgent problem in the field of electrode processing. To solve these problems, from a technical point of view, it is necessary to realize the integration of CAD / CAPP / CAM. To realize the integration of CAD / CAPP / CAM, on the one hand, it is necessary to exchange product data between differe...
