METHOD FOR MONITORING CUTTING-TOOL ABRASION

摘要

A method for monitoring cutting-tool abrasion of a machine tool includes the steps of: defining a tolerance range of abrasion of a cutting tool; collecting loading data of the cutting tool at every continuous machining sections; extracting actual-cutting loading data from all the loading data; calculating coefficients of fitting lines of the loading data for individual machining sections according to the actual-cutting loading data; comparing the abrasion of the cutting tool according to the tolerance range and the fitted lines; and, if an outranged result occurs, issuing an alert message to adjust or to replace the cutting tool.
