摘要：

A computer-based adaptive system for the closed-loop control of the cutting temperature is modelled and designed for application to a lathe turning process. The cutting temperature is estimated through e.m.f. measurements obtained by using a standard thermocouple embedded in the tool bolder. The control objective is to maximise the metal removal rate subject to constraints on tool decay related to temperature-dependent wear mechanisms. A real-time monitoring and control strategy is implemented aiming at compensating for process dynamics variations according to a self-tuning regulator scheme. (C) 1998 Elsevier Science S.A.
