Document Type and Number:
WIPO Patent Application WO/2020/213387
Kind Code:
A1
Abstract:
This method for detecting wear of a cutting tool (7) for cutting a workpiece (W) comprises: a step for converting, into frequency waveform data, time waveform data of a monitoring signal output from a sensor (15) that detects a vibration of the cutting tool (7) during cutting processing of the workpiece (W); a step for obtaining, from the frequency waveform data, processing resistance during cutting processing of the workpiece (W); and a step for detecting wear of the cutting tool on the basis of the processing resistance.
