Abstract

Spray forming is a new manufacturing process. The automated tool planning for this process is a nontrivial problem, especially for geometry-complicated parts consisting of multiple freeform surfaces. We have developed a tool path planning system which can automatically generate optimized tool plans. This paper focuses on the path integration problem, or how to connect the paths from different surface patches so that the overall path length is minimized. A genetic algorithm is developed to solve the integration problem. Experimental tests are carried out on automotive body parts and the results validate the proposed algorithm

基于遗传算法的喷射成形过程刀具轨迹集成
喷射成形是一种新型的制造工艺。对于由多个自由曲面组成的几何复杂零件,刀具的自动化规划是一个非常重要的问题。我们开发了一个刀具轨迹规划系统,可以自动生成优化的刀具轨迹规划。本文主要研究路径整合问题,即如何将来自不同表面斑块的路径连接起来,从而使总路径长度最小化。提出了一种求解积分问题的遗传算法。在汽车车身零件上进行了实验测试,结果验证了该算法的有效性
