Embodiment Construction

[0016] A three-dimensional process model generation method based on the combination of forward and reverse sequences proposed by the present invention adopts the combination of forward and reverse sequences of the three-dimensional process model, divides the process into frame node processes and sub-processes, and divides the process model into frame node process models And the sub-process model, constructing a structured process by reading the prior process knowledge and decision results in the model seed file to realize the association between manufacturing features, processes and modeling operations. The frame node process model is created by the forward sequence method, and the generation efficiency is high; on the basis of the frame node process model, the sub-process model is constructed by the reverse sequence method. In the process of sub-process model generation, based on the association and correspondence between manufacturing features, processes and modeling operatio...

Abstract

The invention discloses a method for generating a three-dimensional process model based on the combination of positive sequence and reverse sequence in the field of three-dimensional digital process design. Firstly, the design model is read and a blank model is established; the process information and process frame flow of the part are constructed, and then the frame node of the process frame of the part is established. Process model, build the process model of all operating parts changes in each stage of processing in reverse order, and finally complete the establishment of all process models; the invention realizes the support for parallel work and collaborative design of process design, and can improve the process and efficiency of three-dimensional process design; In the process of generating the three-dimensional process model, the method of combining the forward sequence manual interaction design of the frame node process model and the automatic reverse sequence generation of the small process node process is adopted to support various modeling software and improve the efficiency of process model generation.

Description

technical field [0001] The invention belongs to the field of three-dimensional digital process design, and is a method for generating a three-dimensional process model based on the combination of positive and negative sequences. That is, in the three-dimensional process design, the process model is divided into a frame node process model and a sub-process model. The forward sequence method is used to construct the frame node process model by deleting or suppressing features or model operations; the reverse sequence method is used to construct the sub-process model by using the frame node process model as input and the automatic generation of synchronous modeling. Background technique [0002] With the rapid popularization and development of 3D software, my country's manufacturing industry has basically realized 3D product design. However, most of the process design, which is an important part of the digital design and manufacturing platform, is still based on two-dimensiona...
