672.~ Defined electrolyte movement or pressure

DEFINITION

Classification: 205/672

Defined electrolyte movement or pressure:

(under subclass 640) Process in which a particular path of motion or pressure is imparted to the electrolyte during the erosion process (e.g., submerged jet action, etc.).

(1) Note. A recitation of merely passing electrolyte between the tool and workpiece is not sufficient for classification in this subclass.

668+, for electrolytic erosion with local application of the electrolyte to contact only a portion of a workpiece surface.
