Embodiment Construction

[0040] The present invention provides a kind of model rebuilding method based on edge movement, comprises the following steps:

[0041] Step 1. For the model to be reconstructed, select its offset edge and set the offset vector

[0042] In this embodiment, the model reconstruction method utilizes Grasshopper software, firstly, the model, offset edge and offset vector of the sheet metal part are input and stored in a list.

[0043] Step 2. Find and record the offset-related faces and irrelevant faces in the model respectively

[0044] Find the faces in the model that are related to the offset edges, record them as relevant faces and record them, and these faces need to be reconstructed after online migration; find out the faces that have nothing to do with the offset edges, and record them as irrelevant faces, which is convenient for the final Model reconstruction.

[0045] Step 3, check whether there is a hole on the relevant surface (generally, the default is a hole through...

Abstract

The invention discloses a model reconstruction method based on edge movement. The method first inputs a model, an offset edge, and an offset vector, and respectively records the relevant surface and the irrelevant surface of the offset edge; Afterwards, the model is reconstructed; for the non-porous model, the relevant edges and irrelevant edges of the offset edges are recorded respectively, and the relevant edges are offset, and the relevant surfaces are reconstructed, and finally the reconstructed model is obtained. This method can quickly and conveniently perform parametric reconstruction of the workpiece model or modify or supplement the shape of the existing model; compared with the current traditional method, it effectively saves human resources, is simple to operate, reliable in use, reduces the work intensity of workers, and breaks the production line. Time constraints can effectively improve production speed, and can adapt to the rapid reconstruction of large-scale models, and can also rebuild models with holes.

Description

technical field [0001] The invention relates to the field of manufacturing, in particular to a model reconstruction method based on edge movement. Background technique [0002] In the manufacturing industry, workpiece modeling is a necessary manufacturing link for mass production of sheet metal parts. The quality and speed of modeling often determine the efficiency and effectiveness of production. In the modeling process of complex workpiece models, sometimes it is necessary to quickly and conveniently rebuild the (batch) model under the condition of size constraints, or to modify or supplement the shape of the existing model. For the modeling of large batches of workpiece models The process can effectively improve the quality and efficiency of modeling. [0003] The existing model reconstruction method is cumbersome, heavy workload, low efficiency, and cannot be reconstructed for the model with holes on the surface. Contents of the invention [0004] The purpose of the ...
