Milling is a machining operation in which a workpart is fed past a rotating cylindrical rotating tool with multiple cutting edges. The axis of rotation of the cutting tool is perpendicular to the direction of feed.
Milling Machines A milling machine is a power driven machine that cuts by means of a multitooth rotating cutter. The mill is constructed in such a manner that the fixed workpiece is fed
The experimental results showed that down-milling operation has better results in terms of tool wear than up- milling operation.Investigations have been made into the effects of cutting speed, feed rate and depth of cut ( DOC) on the tool life.

Cutting speed. Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.

Milling is a cutting process that uses a milling cutter to remove material from the surface of a workpiece. The milling cutter is a rotary cutting tool, often with multiple cutting points.As opposed to drilling, where the tool is advanced along its rotation axis, the cutter in milling is usually moved perpendicular to its axis so that cutting occurs on the circumference of the cutter.
