摘　　要：可转位成形盘铣刀的切削刃由多个可转位刀片组成,由于铣削转子螺旋槽加工为分层切削,使按传统经验法确定的刀片周向分布及分层切深易造成实际铣削时功率严重波动情况。为了解决上述问题,以抑制刀盘铣削功率波动为优化目标,提出基于遗传算法的刀片周向分布和螺旋槽分层切削深度的优化模型。为了分析刀盘铣削时可转位刀片的切削组合,提出径向边界和周向边界判定法,并以此为基础建立刀盘切削功率的计算公式,并采用优化算法获得优化后的刀片周向分布位置和螺旋槽分层切深。通过对实际刀盘案例进行优化,验证了优化方案的可行性和实用价值。The cutting edge of the indexable formed disk-type milling cutter is composed of multiple inserts, and the milling of the rotor spiral groove is divided into multiple layers.On this conditions, the circumferential distribution and layered cutting depth of the insert determined by the traditional empirical method is easy to cause serious power fluctuation in actual milling.Therefore, in order to solve above problems, an optimization model of blade circumferential distribution and layered cutting depth based on genetic algorithm is proposed to suppress the fluctuation of cutter milling power.In order to analyze the cutting combination of the transferable blades in the milling of the cutterhead, the determination methods of the radial boundary and the circumferential boundary are proposed, and the calculation formula of the cutting power of the cutterhead is established on this basis.The circumferential distribution position and the layered cutting depth of the optimized blade are obtained through the optimization algorithm.The optimization analysis of the actual cutterhead case verifies the feasibility and the use value of the optimization scheme.
