Milling Machine: Definition, Parts, Operation, Application ...
Milling Machine Definition: The milling machine is a type of machine which removes the material from the workpiece by feeding the work past a rotating multipoint cutter.The metal removal rate is higher very high as the cutter has a high speed and many cutting edges. It is the most important machine in the tool room as nearly all the operations can be performed on it with high accuracy.

Drilling, Cutting And Grinding System Mechanism
6. Operation of any complicated components can be done with this machine Future Scope 1. We can perform various operations like cutting, drilling, or grinding individually by introducing coupling (engagement & disengagement) between them. 2. We can perform grinding operation by introducing a grinding tool at the main shaft. 3.
MACHINING OPERATIONS AND MACHINE TOOLS
Machining Operations and Part Geometry Each machining operation produces a characteristic part geometry due to two factors: 1. Relative motions between the tool and the workpart •Generating –part geometry is determined by the feed trajectory of the cutting tool 2. Shape of the cutting tool •Forming –part geometry is created by the

Shaping, Planing and Slotting Operations
The Shaper The machine tool used for shaping operation is called shaper. It is designed for machining flat surfaces on small sized jobs.If the size of the job is large, then planing is used. In a shaper, the work piece is held stationary during cutting, while the tool reciprocates horizontally. the feed and depth of cut are normally provided by moving the work.
