Online real-time cutter breakage monitoring method
An online real-time cutter breakage monitoring method uses a plurality of signals generated in three consecutive time periods by a vibration acceleration during a cutting process conducted by a CNC machine tool, and compares a difference between a maximum value of signals in each time period and an average value of the signals and a difference between the average value of signals thereafter and an idling critical value to output a first cutter breakage signal and a second cutter breakage signal simultaneously and determine the occurrence of a cutter breakage and shut down the CNC machine tool immediately to improve the determination speed and accuracy, so as to avoid unnecessary shutdowns or hindering the manufacturing flow.
