(under subclass 324) Subject matter wherein cutting is effected by means comprising a pointed or edged element rigidly attached to or constituting a portion of a disclosed metal-deforming tool*, which element engages work at some time during the disclosed motion of said tool or during the disclosed motion of an associated metal-deforming tool forming therewith a tool couple*, during which disclosed motion an operation of the class type is also performed upon the same work or upon metal material integral therewith.
(1) Note. A composite metal-deforming and cutting tool may be either an actuated or a fixed tool, or there may be co-acting cutting edges on both elements of a metal-deforming tool couple.
(2) Note. The cutting may take place before, during, or after a claimed deforming operation by said tool upon the same workpiece or upon integrally connected material (such as stock, partially treated work, undetached product portion,
etc.). It must in all cases be regularly associated with a deforming operation, i.e., in the same tool stoke, and not as an optional or alternative use of the tool.
(3) Note. This subclass is the residual locus for patents directed to process or apparatus involving a composite tool which cuts by sawing, drilling, tearing, nipping, incising, puncturing, or other nonshearing action. See following diagram for an example of a composite tool; (other examples in subclasses 327 and 330).
(4) Note. See search notes under subclasses 464 of this class for listing of other subclasses providing for composite cutting-deforming tools. [figure] [caption]Composite cutting-and-deforming tool (subclass 325)
