GEAR CUTTING, MILLING, OR PLANING
Class Definition:
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).

Apparatus or method (1) employing a multitoothed cutting tool
characterized in that: (a) the functional edges of the tool
teeth are so related to one another that the tip of one tooth
extends further than that of an adjacent tooth from a datum
line interior to the tool and paralleling the path of
relative movement of tool and work (which extent is measured
along the normal to such datum line through the tip); and (b)
the differences in such extent between adjacent teeth are
progressive from tooth to tooth (or group of teeth to group
of teeth) along such path of relative movement, resulting in
a stair-step arrangement of teeth (or groups of teeth) along
such path and relative to the datum line of reference; and
(2) in whose operation or performance the teeth succesively
engage the work in substantially overlying paths, each tooth
removing a predetermined amount of material so that the work
modification produced is congruent to the last acting tooth.
(1) Note. Illustrative broach tools are shown in the
accompanying drawings. (See accompanying drawings below).

(2) Note. In the case of rotary tool motion, it will be
noted that the normal to the datum line (referred to in the
definition) is the radius extending through the tooth tip.

part (1, b) of the above definition, the progressive extent
of differences between the tips (or outer cutting edges) and
the datum line is intended to include a tool comprising a
plurality of groups or units of several teeth each, the tooth
