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, and the method comprises the steps: firstly inputting a model, an offset edge and an offset vector, and respectively recording a related surface and an unrelated surface of the offset edge; for the model with the holes, reconstructing the model after reconstructing the holes; and for the non-porous model, respectively recording related edges and irrelevant edges of the offset edges, and reconstructing the offset and related surfaces of the related edges to finally obtain a reconstructed model. According to the method, parameterized reconstruction can be quickly and conveniently carried out on the workpiece model or shape modification or supplement can be carried out on the existing model; compared with a currenttraditional mode, manpower resources are effectively saved, operation is easy, use is reliable, the working intensity of workers is reduced, the constraint of production time is broken through, the production speed is effectively increased, and the method can adapt to rapid reconstruction of large-batch models and can also be used for reconstruction of perforated models.

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 ...
