汽车覆盖件模具高效铣削轨迹规划

摘要
针对刀具路径规划问题及其优化算法展开研究。通过研究可知,在深入分析传统刀具路径轨迹规划方式基础上,有效弥补传统刀具轨迹规划单一考虑刀具与工具之间的几何关系,并没有关注切削加工操作中各类物理因素对加工操作的影响。同时,把刀具路径轨迹规划问题转变成为TSP问题,通过遗传算法有效解决TSP问题。在此基础上,借助MATLAB仿真试验检验这种方式用于刀具轨迹规划的正确性及可行性。
This paper focuses on the problem of tool path planning and its optimization algorithm. Through the research, we can know that, on the basis of in-depth analysis of the traditional tool path planning method, the traditional tool path planning is effectively made up via single consideration of the geometric relationship between the cutting tools and tools, while not taking the influence of various physical factors on machining operations in consideration. At the same time, the tool path planning problem is transformed into TSP problem, which is solved effectively by genetic algorithm. On this basis, the correctness and feasibility of this method for tool path planning are verified by MATLAB simulation test.
