一、引言柔性制造系统(FMS)的主要目标是实现加工生产的无人化或少无人化,从而极大地提高设备利用率和经济效益。为此,FMS必须具备自动检测监控的机能,以保证系统的可靠性和产品的质量。其中,刀具状态的监控尤为重要,虽然刀具寿命管理可防止刀具的磨损和破损,但因刀具寿命的随机性,其寿命极限估计值往往过于保守,以致大部 I. INTRODUCTION The main goal of flexible manufacturing system (FMS) is to realize the unmanned or unmanned processing of production, thus greatly improving equipment utilization and economic benefits. To this end, FMS must have automatic detection and monitoring capabilities to ensure the reliability of the system and product quality. Among them, the tool status monitoring is particularly important, although the tool life management to prevent tool wear and tear, but due to the randomness of tool life, life expectancy estimates are often too conservative, so most
