Milling This is the process of metal removing by a milling cutter which is rotated against the direction of feeding of work of the cutter. The chip thickness is minimum at the beginning of the cut and reaches maximum at the end. Because of this, the cutting force in up milling increases from zero to the maximum value per tooth movement of the cutter. As the cutting progresses and there ...

Machine Definitions: A milling machine is a machine tool that removes metal as the work is fed against a rotating multipoint cutter. OR It is a machine tool in which rotating multipoint cutter is used for extracting the material from the work piece. Feature: Due to multi point cutting edges with high speed of rotation, the rate of metal removal MRR is very high.
