基于多色集合理论的数控加工刀具优化选择研究

Study on the Optimum Choice of Cutting Tools in NC Machining Based on the Polychromatic Sets Theory

基于建立刀具选择的关系模型并以围道布尔矩阵的形式表示,通过多色集合中着色的逻辑运算,找到满足加工条件的候选刀具集合并对其进行模糊优选;综合考虑换刀时间,加工顺序以及其它相关加工信息对刀具选择的影响,使选择刀具在整体上达到最佳化。

A relational model of cutting tools choice was established,which was shown with a contour Boolean matrix.Through the coloring logical operation,the cutting tools candidate set was calculated to meet machining conditions.With the candidate cutting tools set,the fuzzy optimization was made for every part feature.And with considering the effects of the time of cutting tools exchange,processing sequence and other relevant information for the selection of cutting tools,the choice of cutting tools is optimized as a whole during machining.
