Embodiment Construction

[0049] The present invention will be described in further detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0050] The component processing-oriented process model construction method of the present invention takes component processing as the research object, and aims to provide an effective way for component processing three-dimensional process design, to realize process design and information expression using three-dimensional models as carriers, replacing traditional two-dimensional Dimensional paper documents solve the problems of unintuitive expression of two-dimensional process design information and various types of carriers for component processing, and realize the guidance of production and manufacturing with three-dimensional models.

Abstract

The invention discloses a component processing-oriented process model construction method and belongs to the information processing field. According to the invention, different technological types are processed according to technological procedures. According to the process model construction method, during a machining step, the association relationship between geometric feature nodes, annotation feature nodes and the machining step is established. During a welding step, mated parts to be welded are successively selected and the association relationship between the welding step and the to-be-welded parts is established. During an assembling step, to-be-assembled parts and assembly tools are successively selected and the association relationship between the assembling step and the o-be-assembled parts is established. During an auxiliary step, for clamping, coating, plating, checking and other operations that do not involve in the variation of model geometric features, the association relationship between the auxiliary step, the geometric feature nodes and the annotation feature nodes is established. During the machining step, the welding step, the assembling step and the auxiliary step, the input required during the method is conducted in the 3D annotation and attribute assignment manner.

Description

technical field [0001] The invention relates to a process model building method, in particular to a component processing-oriented process model building method. Background technique [0002] The 3D CAD (Computer Aided Design) system has now become the basic platform for digital design and manufacturing of enterprises, and the realization of product design based on the 3D CAD system has become very popular. However, the current process design is mostly based on 2D engineering drawings, and the 3D model is only used as a reference for process design, not legal data input, and the 3D design model cannot be effectively used, resulting in inconsistent design process data sources and difficult to maintain correlation. [0003] Component processing is an important process method, which is usually carried out after the parts are assembled or welded to form a whole, such as matching, post-welding processing, etc., to eliminate deformation and error accumulation, and ensure the accura...
