Milling is the machining process in which the removal of metal takes place due to the cutting action of a rotating milling cutter.In a milling machine, the cutter is rotating due to workpiece is fed against it.This machine can hold more than one tool at a time. The cutter rotates at high speed, and because of the many cutting edges, it removes metal at a very fast rate.

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 process of "milling" entails a rotating cutter, or drilling bit, and a movable work table, which the workpiece is affixed to. The cutter is attached to and rotated in a housing called the "spindle." Through the sharpness of the tool and force of the table pushing the material into the cutter, the material yields and is cut or shaved ...

Work Positioning: •The method of accurate work positioning in relation to the cutting tool is called the "rectangular coordinate system." On the vertical mill, the horizontal base line is designated the "X" axis, while the vertical base line is designated the "Y" axis.

The base of the machine is mounted either on a bench or on the floor by means of bolts and nuts. It can handle drills upto 15.5mm of diameter. The drill is fed into the work purely by hand. The operator can sense the progress of the drill into the work because of hand feed. The machine …
