Abstract

With the increasing use of computer numerical control, there is a growing need to ensure a reliable tool wear monitoring system to optimize tool usage or tool wear. Findings have shown a good correlation between the dynamic tangential force and flank wear. A software program is being developed currently on a personal computer installed with a Fast Fourier Transform card. The FFT card transformed the signals collected during cutting process to obtain more meaningful results. A pre-warning condition can be set in the software program to indicate the onset of tool failure when the dynamic force starts to decline. So far, the progress has been very promising.
