Title:
METHOD FOR DETECTING INTEGRITY INDEX OF MACHINE TOOL
Document Type and Number:
WIPO Patent Application WO/2020/138694
Kind Code:
A1
Abstract:
Disclosed is a method for detecting an integrity index of a machine tool, the method comprising: an integrity information collection step of collecting the amount of current consumed in a process of machining a workpiece over time when the machine tool is in a normal state; a first failure information collection step of collecting the amount of current consumed in the process of machining the workpiece over time when the machine tool is in a worn state; a setting step of setting an integrity reference value and a failure reference value on the basis of information collected in the integrity information collection step and the first failure information collection step; an extraction step of collecting the amount of current consumed in the process of machining the workpiece in real time using the machine tool over time and extracting a measurement value from the collected information; a detection step of detecting an integrity index value of the machine tool by comparing the measurement value extracted in the extraction step with the integrity reference value and the failure reference value set in the setting step; and an output step of outputting the integrity index value detected in the detection step and providing the integrity index value to a manager.
