Title:
METHOD AND SYSTEM FOR DETERMINING TOOL DAMAGE OF WORK MACHINE
Document Type and Number:
WIPO Patent Application WO/2022/080505
Kind Code:
A1
Abstract:
The present invention includes: a step for detecting machining vibrations during machining; a step for analyzing the machining vibrations through Fourier series expansion so as to obtain a machining frequency; a step for extracting, from the machining frequency, a total sum TPF that is the total sum of a tool passage frequency and a harmonic thereof and a total sum SRF that is the total sum of a main shaft rotation frequency and a harmonic thereof; and a step for making a comparison between the total sum TPF and the total sum SRF so as to determine whether or not a rotation tool is damaged.
