Abstract
An ultrasonic generator and a method for controlling an oscillator unit (13) of the ultrasonic generator (10) in a machine tool for generation of ultrasound to excite a tool (26). A control variable for controlling a frequency f of an electrical control signal HFS generated by the oscillator unit (13) is determined depending on an analysis of the size of an input and/or output current I or of an input and/or output power P of the ultrasonic generator (10).
Claims12
A method for controlling an oscillator unit (13) of an ultrasonic generator (10) in a machine tool for the generation of ultrasound to excite a tool (26) for machining a workpiece, wherein a control variable is determined for controlling a frequency f of an electrical control signal generated by the oscillator unit (13),
- characterized in that the control variable is determined depending on an analysis of the size of an input and/or output current I or of an input and/or output power P of the ultrasonic generator (10).
An ultrasonic generator (10) in a machine tool for generation of ultrasound to excite a tool (26) for machining a workpiece, comprising:
- an oscillator unit (13) designed to emit an electrical control signal HFS with a frequency f for generation of the ultrasound,
- a control unit (12) designed to determine a control variable for controlling the frequency f of the electrical control signal HFS generated by the oscillator unit (13),
- characterized in that the control unit (12) is designed to determine the control variable depending on an analysis of the size/amplitude of the input and/or output current I or of a size/amplitude of the input and/or output power P of the ultrasonic generator (10).
