Abstract
PURPOSE:To make it possible to detect various kinds of abnormal mode with a single comparator, by integrating the detection signal, which is output from a detector, by an integrator and by comparing the integral value with the integral value of normal data. CONSTITUTION:Detector 1 consisting of piezoelectric elements and so on is fixed to the tool post or the cutting tool of a machine tool and detects accelerating vibration of machine vibration generated in these tools during the cutting process and inputs it to amplifier 2. Integrator 3 is connected to amplifier 2, and the detection signal is integrated, and the integral value is input to comparator 4. Meanwhile, information unit 5 is connected to comparator 4, and the integral value is compared with normal data; and if it exceeds normal data, anomaly occurrence is decided to input the anomaly signal to control unit 6. Control unit 6 stops the machine tool, issues alarm, and so on.
