Glossary of Terms
Arbor: a tapered shaft that holds a cut ting tool.
Collet: a tapered shaped split-sleeve bushing
that holds round tools by their outside diameter.
Cutting Speed : the distance a point on a cut-
ter moves in one minute, expressed in surface
meters or feet per minute.
Dial Indicator: an instrument used in setup and
inspection work that shows the amount of error in
size or alignment of a part.
Dividing Head: a milling machine accessory
used to divide a circular object into a number of
equal parts.
Down or Climb Milling: Feeding the workpiece

face Milling: the milled surface in this method
results from the combined action of cutting edges
located on the face or end of the cut ting tools.
Milling feed : this is the product of multiplying
the desired chip size by the number of teeth on
the cutter and the cutter rpm. it is usually mea-
sured in inches per minute.
fixture: a device that securely holds the workpiece
in place during a cutting operation.
form Milling: the machining of irregular con-
tours by using form cutters.
Gang Milling: When more than t wo cutters are
mounted on the arbor to machine surfaces of a
workpiece.

which the table, saddle, and knee travel.
X-Axis: the path the table travels left-to-right.
y-Axis: the path the table travels in or out.
z-Axis: the path the table travels up or d own.
