Milling is one of the processes by chip removal machining. The milling process requires a basic equipment. Basic equipment consists of milling machine, work-piece, fixture and cutter. The most important element in the process of milling is necessary machinery. This machine is called milling. There are different types of milling. The routers according to tool orientation can be horizontal, vertical or universal.

Operations during the milling process cycle are as follows:

• End milling: Tool mill makes peripheral and slot cuts across the work-piece.
• Chamfer milling: Tool mill makes a cut along of the work-piece to create a 45 degree angled.
• Face milling: Machine works in a flat surface of the work-piece to create a smooth finish.
• Other operations are drilling, boring, counter boring, countersinking, tapping and reaming.
