CNC Method for measuring indirectly tool wear of CNC machine

摘要

The present invention relates to a method for indirectly measuring tool wear of a CNC machine tool, and more specifically, to a method for indirectly measuring tool wear of a CNC machine tool implemented in a computer, (a) data related to tool wear from a running CNC machine tool. Real-time data collection step of collecting in real time; (b) converting the real-time data collected in the step (a) into statistical values and pre-processing them; (c) If the number of times the current tool is used is stored separately as reference data, and if the number of times the current tool is used is two or more times, calculating predicted normal data values through vector calculation between the real-time data and the reference data ; (d) calculating a residual value as an absolute value of the difference between the predicted normal data value and the real-time data value calculated in step (c); And (e) converting the residual value calculated in step (d) into an indirect measurement value of tool wear.
