Abstract: The availability of a reliable tool wear and failure monitor remains one of the few remaining obstacles to an efficient fully automated production system. The present study examines the efficiency of the dynamic component of cutting force in providing ample signs of imminent tool failure either by fracture or chipping. To induce faster tool breakage a shallow groove is machined on the tool rake face by electro-discharge machining. Results show that, generally, prior to the event of tool breakage there is a sharp rise in the characteristic peak amplitude which subsequently falls rapidly. This forewarning is decidely advantageous if machining is to be stopped in time before disruptions set in. © 1988.
