Abstract

The invention relates to a method for operating an ultrasonic tool, wherein a control signal with specific frequency characteristics is applied to the tool and a workpiece is machined using ultrasonic tool. During said machining process, the temporal progression of an electrical variable is determined in the ultrasonic tool as a measuring signal, as are a phase or phase change between the control signal and the measuring signal. A frequency characteristic of the control signal and/or the advance of the tool is controlled according to the result of the analysis.
