DEFINITION

Classification: 409/64

MILLING:

(under the class definition) Apparatus or method comprising use of a cutting tool rotatably driven through more than 360 deg. to form a shaped surface on a workpiece.

SEE OR SEARCH THIS CLASS, SUBCLASS:

243+, for a rotary broaching machine. Note that a rotary broach normally turns through no more than 360 deg. to form a shaped surface on a workpiece and is therefore excluded from this and the indented subclasses.

SEE OR SEARCH CLASS

408, Cutting by Use of Rotating Axially Moving Tool, for a machine for cutting by use of a tool turning about an axis and moving along that axis toward a workpiece wherein no additional motion is imparted to the cutting edge of the tool during operation. Especially

26+, for the combination of cutting in the manner of that class (408) with cutting in the manner of this class (409). The use of a tool to cut in the manner of Class 408 and then in the manner of this class will be found in this class (409).

451, Abrading,

119+, for an abrading machine using a rotating tool which also has reciprocating motion and subclasses 177+ for an abrading machine using a rotating abrading tool in which the work is manipulated relative to the tool. 470, Threaded, Headed Fastener, or Washer Making: Process and Apparatus,

60+, for a machine for milling a driving slot in the head of a screw; subclass 107 for a machine for finishing the sides of a rough nut blank by means of a milling cutter; and subclass 161 for a machine for milling a slot in the shank of

a rivet to from a split rivet.

483, Tool Changing,

30+, for apparatus including a rotary spindle machine tool combined with a tool transfer means.
