DEFINITION

Classification: 205/662

With mechanical abrasion or grinding:

(under subclass 640) Process in which a solid makes moving contact with the workpiece to scrape or rub material from a surface of the workpiece.

(1) Note. The abrasive solid may be attached to a tool or may be loose.

(2) Note. The abrasion or grinding may occur simultaneously with or subsequent to electrolytic erosion.

652+, for electrolytic erosion in which solid nonabrasive particles are used to maintain a tool-workpiece gap.

661, for electrolytic erosion with preliminary nonelectrolytic cleaning or shaping of the workpiece. 709, for electrolytic cleaning involving moving contact of a solid member with a workpiece.
