【摘要】 刀具的磨损与具体的加工状态直接相关，在一般的ＦＭＳ刀具管理中，大多采用切削时间累加的方法进行刀具寿命管理，此法难于准确衡量刀具的磨损。该文首次提出刀具相对磨损率的概念，采用建立切削数据库的方法，得到刀具相对磨损率的计算公式，并应用于ＦＭＳ刀具管理中，以进行刀具寿命的优化管理。实例计算表明，此方法是可行的。更多还原

【Abstract】 Tool wear is directly related with specific cutting conditions. In a general FMS tool management system, tool life is decided by the total cutting time that a tool is used. This method is inaccurate to judge the tool wear states. In this paper, a new concept,tool relative wear ratio,is proposed. Using cutting database, a formula to calculate the tool relative wear ratio is presented and used in FMS tool management system so as to realize the optimal management for FMS tool life. Examples show that this method is feasible in practice.更多还原
