Title:
METHOD FOR DETECTING INTEGRITY INDEX OF TOOL OF PROCESSING MACHINE
Document Type and Number:
WIPO Patent Application WO/2020/138693
Kind Code:
A1
Abstract:
Disclosed is a method for detecting an integrity index of a tool of a processing machine, comprising: an integrity information collection step of collecting the amount of current consumed according to time in a process of processing a workpiece when the tool of the processing machine is in a normal condition, wherein the amount of current is classified into an inflow section, a constant speed section, and an outflow section; a first defective information collection step of collecting the amount of current consumed according to time in the processing machine, in a process of processing the workpiece before the tool of the processing machine is broken, wherein the amount of current is classified into the inflow section, the constant speed section, and the outflow section; a setting step of setting a warning value and a risk value for each of the inflow section, the constant speed section, and the outflow section on the basis of the information collected in the integrity information collection step and the first defective information collection step; an extraction step of collecting the amount of current consumed according to time in a process of processing the workpiece through the tool of the processing machine in real time, wherein the amount of current is classified into the inflow section, the constant speed section, and the outflow section; a detection step of detecting the number of times that the amounts of current in the inflow section, the constant speed section, and the outflow section, collected in the extraction step, exceed the warning values and the risk values for the inflow section, the constant speed section, and the outflow section, set in the setting step, and detecting a value of an integrity index of the tool of the processing machine; and an output step of outputting the value of the integrity index detected in the detection step and providing same to an administrator.
