ABSTRACT:
The service life of a cutter is determined with high accuracy by determining a corrective coefficient from a material coefficient determined by a material to be machined by the cutter and a machining condition coefficient determined by machining conditions, multiplying a period of usage of the cutter by said corrective coefficient thereby to correct the period of usage, accumulating corrected periods of usage, and judging the cutter as having ended its service life if the accumulated value exceeds a predetermined reference value.
