Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0033] Such as Figure 1-5 shown.

[0034] A fast search method for processing operations based on feature identification, which firstly assigns an identification value to each generated feature during feature identification of parts, and the identification values ​​of each feature in the feature identification results do not coincide. When generating the processing operation of the part, the identification value corresponding to each feature is assigned to the processing operation corresponding to the processing feature, so as to realize the association between the feature and the processing operation based on the feature identification value. When searching for processing operations, click the geometric element on the part model that needs to be searched for processing operations, search for the feature that the geometric element belongs to, extract ...

Abstract

A machining operation rapid search method based on feature identification is characterized by including the steps of firstly, assigning an identification value to each generated characteristic when characteristic recognition is conducted on a part; secondly, assigning the identification value corresponding to each characteristic to the machining operation corresponding to the machining characteristic when the machining operation for the part is generated so as to associate the characteristic based on the corresponding characteristic identification value with the machining operation; thirdly, selecting geometrical elements of the machining operation to be searched for on a part model through mouse clicking in the search process, searching for the characteristics to which the geometrical elements belong, extracting the identification values of the characteristics, searching a list of the machining operation of the part for the machining operation containing the identification values, and enabling rapid search to be achieved. According to the method, the numerical control programming efficiency of technologists can be effectively improved, and technological preparation time can be effectively shortened.

Description

technical field [0001] The present invention relates to a CAD / CAM technology, especially a method for quickly completing process programming by finding the processing operation of required processing features in a large number of edited processing programs, specifically a processing based on feature identification Operation Quick Find method. Background technique [0002] At present, CAD / CAM technology has been widely used in the field of modern manufacturing, especially in the aspect of numerical control programming. The emergence of CAM technology has improved the programming efficiency of craftsmen to a certain extent, improved the processing efficiency, and shortened the manufacturing cycle of products. , saving production cost. Especially in large aeronautical structural parts, the advantages of CAM technology are more obvious. However, with the advancement of technology and changes in requirements, large-scale integral structural parts have emerged as the times requi...
