Feature-basedthree-dimensional machiningtechnology layout system and method

Abstract

The invention relates to a feature-basedthree-dimensional machiningtechnology layout system and method. The system in the same interface comprises a feature technology tree region, a feature technology attribute region, a technology leveling grid region and a process and step attribute region. The feature processing method is expressed by utilizing a feature technology tree and a feature technology attribute, and the process and the step of the part machining technology are expressed by utilizing the process leveling grid and the process and step attribute. The method comprises the first step of generatingthe feature processing method, the second step ofperforming feature step sequencing torapidly generate the part technology and the third step of combining, merging and sequencing the technology routine. After the content completion of the process and the step and through the combination, merge and sequence of each feature technology routine of parts, and the final part technology routine is obtained. The feature-basedthree-dimensional machiningtechnology layout system and methodhave the advantages of the information organization, the processing knowledge inheritance and the integration of the structural technology, and make the technology layout easier and faster.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional machining, and in particular relates to a feature-based three-dimensional machining process layout system and method. Background technique [0002] With the development of computers and related technologies, form-filling CAPP systems based on Word / Excel / AutoCAD and other graphics systems have been widely used in enterprises. At present, enterprises generally use two-dimensional machining process design software. The process content and planning process of the form-filling CAPP system are formed in the mind. By filling in the process form, the preparation of the process card is completed. The process is in the process card (or in an independent two Dimension list area) and process steps are edited in process cards; process data and card formats are packaged and stored in files or databases in an unstructured manner. The content in the process card of the form-filling CAPP system is discr...

AI Technical Summary

Problems solved by technology

This method of expression cannot simultaneously see the complete information of the process and its associated steps in one interface, which is not conducive to the editing operation of the craftsman

Due to poor usability, it affects the application of products in 3D process design

[0004] Neither type of system provides a good method for process orchestration in terms of feature-based 3D process design
