Automatic generation of non-circular punches and dies in die CAD (4)

Figure 4 shows the flow chart of the convex model generation

Third, the automatic generation of the concave mold

For the non-circular die, it is first necessary to determine the outer dimensions of the die. After determining the size of the die, the cavity is generated in the same way as the non-circular die, except that a section line is selected before the generation. The intersection of the section line and each entity is regenerated, and the closed line is regenerated, and then the non-circular die is generated by the same method as the generation of the non-circular punch.

Fourth, the conclusion

Aiming at the complexity of designing non-circular punches and non-circular die, the arc is discretized by the "arc polygonization" method, and a method of generating non-circular punches and non-circular die by computer is found. The automatic design of non-circular punches and non-circular die is realized, which improves design efficiency and design quality.
