[0024] In order to illustrate the technical solutions and technical objectives of the present invention, the present invention will be further described below with reference to the drawings and specific embodiments.
[0025] Combine figure 1 , An efficient parallel cutting method of STL model based on common spot welding sequence of the present invention includes the following steps:
[0026] Step 1. Read the STL model and construct the index information of the vertices and edges of the triangle face
[0027] 1.1. Create a storage container:
[0028] Establish an associative container PointToIndex for storing vertices and vertex indexes, and an associative container EdgeToIndex for storing edges and edge indexes. The two associative containers are initially empty, that is, no elements are stored. In addition, to store the coordinates of the three vertices (P 1 , P 2 , P 3 ), the index of the three vertices (PIndex 1 , PIndex 2 , PIndex 3 ) And the index of the three edges (EIndex 1 , ...
