Title:
METHOD FOR PREDICTIVELY MAINTAINING TOOL OF PROCESSING MACHINE
Document Type and Number:
WIPO Patent Application WO/2020/138691
Kind Code:
A1
Abstract:
Disclosed is a method for predictively maintaining a tool of a processing machine, comprising: a first base information collection step of collecting information about a change in the magnitude of current consumed according to time in the processing machine, in a process of processing a workpiece when the tool of the processing machine is in a normal condition, wherein the information about the change in the magnitude of current is classified into an inflow section in which the tool enters the workpiece, a constant speed section in which the tool processes the workpiece, and an outflow section in which the tool leaves, and returns from, the workpiece; a second base information collection step of collecting information about a change in the magnitude 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 information about the change in the magnitude of current is classified into the inflow section in which the tool enters the workpiece, the constant speed section in which the tool processes the workpiece, and the outflow section in which the tool leaves, and returns from, the workpiece; a setting step of setting a first threshold value for each of the inflow section, the constant speed section, and the outflow section on the basis of the information collected in the first base information collection step and the second base information collection step; and a detection step of collecting information about a change in the magnitude of current consumed according to time in the processing machine, in a process of processing the workpiece through the tool of the processing machine in real time, wherein the information about the change in the magnitude of current is classified into the inflow section, the constant speed section, and the outflow section, and when a current value for each section exceeds the first threshold value for each section set in the setting step, detecting as an inspection state that requires inspection or replacement of the tool of the processing machine.
