Milling
Milling is the process of cutting away materialby feeding a work piece past a rotating
multiple tooth cutters. The cutting action of
the many teeth around the milling cutterprovides a fast method of machining. The
machined surface may be flat, angular, or
curved. The surface may also be milled to any
combination of shapes. The machine for
holding the work piece, rotating the cutter,
and feeding it is known as the
Milling machine

METHODS OF MILLING
Up millingis also referred to as conventionalmilling. The direction of the cutter rotation
opposes the feed motion. For example, if the
cutter rotates clockwise , the work piece is fed
to the right in up milling.

METHODS OF MILLING
Down millingis also referred to as climbmilling. The direction of cutter rotation is same
as the feed motion. For example, if the cutter

to the right in down milling
