Working principle of Milling Machine

Operating Principle of Milling Machine :

Milling machine

In a milling machine operating principle machine tool used for the shaping of metal and other solid materials. By use of table and different work holding devices, the work piece is affixed and milling cutter is rotated about the spindle axis. Milling operation involves the movement of the rotating cutter sideways as well as in and out. The cutter and work piece move relative to each other producing a toolpath along which material is removed. Generally in all case of milling multi-tooth cutter is used so that the material removal rate is high and cutting action of the multi-tooth provides a fast method of machining. The machined surface may be flat, angular or curved but the most usually flat surface is produced by a milling machine. Many types of milling machine are used, ranging from relatively simple and versatile milling machine are used for the general purpose of machining to the highly specialized machine for mass production. A milling machine may be operated manually or by CNC or NC machines.
