CNC pocket milling

Pocket milling has been regarded as one of the most widely used operations in machining. It is extensively used n aerospace and shipyard industries. In pocket milling the material inside a arbitrarily closed boundary on a flat surface of a work piece is removed to a fixed depth. Generally flat bottom end mills are used for pocket milling. Firstly roughing operation is done to remove the bulk of material and then the pocket is finished by a finish end mill. Most of the industrial milling operations can be taken care of by 2.5 axis CNC milling. This type of path control can machine upto 80% of all mechanical parts. Since the importance of pocket milling is very relevant, therefore effective pocketing approaches can result into reduction in machining time and cost.
