Machinability detection method of workpiece and cutting method of workpiece by cutting machine using the detection method

摘要

A workability detection method for a workpiece consisting of the steps of cutting a workpiece, based on specified cutting conditions, detecting the cutting resistance during the cutting operation, or the cutting time or the amount of tool wear to make a cut up to a specified position of the workpiece, or the feeding position of the cutting tool on a workpiece or the amount of processing of the cutting tool after a specified cutting time and comparing the detected data with corresponding data which is stored in a data base.
