Milling machine
A milling machine is a machine
tool that removes metal as the work is fed against a rotating multipoint cutter. The milling cutter rotates at high
speed and it removes metal at a very
fast rate with the help of multiple cutting edges. One or more number of
cutters can be mounted simultaneously on the arbor of milling machine. This
is the reason that a milling machine finds wide application in production work. Milling machine
is used for machining flat surfaces, contoured surfaces, surfaces
of revolution, external
and internal threads,
and helical surfaces of
various cross-sections. Typical components produced by a milling
are given in Fig. In many applications, due to its higher production rate and accuracy, milling machine has even replaced shapers
and slotters.
