Class Information
Number: 409
Name: Gear cutting, milling, or planing >
Description: This class is the home for a patent directed to the method of or a machine for penetrating material without substantially reshaping the flow of such material by means of a solid tool whose edge defines a line of cut, where in the device is intended to: (a) form a product from a workpiece, which product includes protuberances intended to interfit with pockets in a cooperating member, generally for the transmission of motive force from one of the members to the other; (b) cut by a rotating cutter that forms a shaped surface on the workpiece; or (c) cut by a cutter that reciprocates relative to a workpiece and forms a shaped surface on the workpiece).
