—Since in broaching the machining operation is completed
in a single-stroke as the teeth on the cutting tool, called broach, are at
gradually increasing height corresponding to the feed per tooth of a milling
cutter.
—The shape of the broach determines the shape of the
machined part.
—Broaching was originally developed for machining
internal keyways, but looking at the advantages, it has been extensively used
in the mass production of automobile component manufacture for various other
surfaces as well.
