Abstract (en)
[origin: WO2020260093A1] The invention relates to a method for detecting whether a slip clutch has been triggered in a machine tool and to a machine tool which is designed to carry out the proposed method. For this purpose, the machine tool comprises in particular a motor as a drive for the machine tool, a controller, a transmission device, a first sensor for detecting a first speed of the transmission device, a second sensor for detecting a speed of the motor, a third sensor for detecting current values, and a slip clutch. According to the proposed method, speed and current values are used in particular in order to detect a slip clutch trigger event.
