Abstract (en)
[origin: WO2021156239A1] The invention relates to a system and a method for controlling an ultrasonic generator of a machine tool for generating ultrasonic waves for machining a workpiece. According to the invention, a determined phase offset of the ultrasonic waves is analysed on the basis of the frequency, and, on the basis of the analysis, a control algorithm for controlling the frequency of the ultrasonic waves generated by the ultrasonic generator is determined.
