Abstract
A method for processing a workpiece on a numerically controlled machine tool by a tool includes the steps of: controlling a relative movement of the tool relative to the workpiece for processing the workpiece, producing an ultrasonic vibration of the tool by an ultrasonic generator, detecting at least one sensor signal outputted from the ultrasonic generator and identifying a change in the material at the workpiece while controlling the relative movement of the tool relative to the workpiece on the basis of the at least one sensor signal outputted from the ultrasonic generator.
Claims14
A method for machining a workpiece on a numerically controlled machine tool by a tool held in a tool receiving portion of a tool holder, the method comprising:
- controlling a relative movement of the tool relative to the workpiece for machining the workpiece based on predetermined processing parameters;
- producing an ultrasonic vibration of the tool by an ultrasonic generator provided in the tool holder, the tool holder being removably received in the machine tool;
- detecting at least one sensor signal outputted from the ultrasonic generator;
- identifying a change in a material of the workpiece while controlling the relative movement of the tool relative to the workpiece based on the at least one sensor signal outputted from the ultrasonic generator, and detecting a temporal change over time and a change in value of one or more parameters of the at least one sensor signal outputted from the ultrasonic generator;
- determining whether the temporal change over time and the change in the value of the one or more parameters of the at least one sensor signal correspondingly fall below a predetermined modification time and simultaneously exceed a predetermined modification value;
- and
- adjusting the predetermined processing parameters when the temporal change and the change in the value of the one or more parameters of the at least one sensor signal correspondingly fall below the predetermined modification time and simultaneously exceed the predetermined modification value.
