DEFINITION

Classification: 205/643

In response to sensed voltage:

(under subclass 642) Process in which the gap voltage or size or a change in the gap voltage or size are adjusted or controlled in response to a detected voltage or change therein.

(1) Note. The detected voltage may either be the gap voltage or any other process voltage.

644, for electrolytic erosion in which a sensed voltage or current is used to control the process without being used to adjust the voltage across or size of the tool-workpiece gap.
