摘　　要：通过理论计算方法,采用长度和时间2个标准,推导出可转位盘形齿轮铣刀的工时函数与成本函数.分析了刀具使用耐用度和名义耐用度的区别与联系,获得了实现最高生产率和最低成本的耐用度计算方法。采用统计手段对某铣削装备加工42CrMo齿圈的耐用度进行分析,拟合换刀策略和进给速度对耐用度的影响函数模型,获得刀具耐用度常数。基于该方法,可对加工方案进行初步评估,确定刀具的最佳耐用度方案。The man hour function and cost function of indexable disk-type gear gasher were derived and calculated by length and time criteria.Meanwhile,the difference and the contraction between the working tool life and the nominal one were analyzed and calculating methods for the maximum productivity and minimum cost strategy were obtained.The tool life was analyzed by statistical method for processing 42CrMo gears and the material gashing constants were calculated by the function model,it was fitted with feed rate and blade-change strategy.Based on the method,the processing program could be preliminary evaluated for the best tool life.
