MASTERCAM X5 -Milling Part 01 by NIlesh Gunjal (ME CAD/CAM) HD

Pocket milling has been regarded as one of the most widely used operations in machining. It is extensively used in aerospace and shipyard industries. In pocket milling the material inside an 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.[1] Most of the industrial milling operations can be taken care of by 2.5 axis CNC milling. This type of path control can machine up to 80% of all mechanical parts. Since the importance of pocket milling is very relevant, therefore effective pocketing approaches can result in reduction in machining time and cost.[2] NC pocket milling can be carried out mainly by two tool paths, viz. linear and non-linear.[3] Morph between two surfaces; Curve 5 axis tool path; Positional facing; Blend tool path ; Face Rough; Finish ; Surface rough pocket; Morph between two curves; Turn mill tool path; Highspeed dynamic estmill tool path; Rotary 4 axis tool path; Engraving ; Nesting; Drilling ; Pocketing; Contouring; Lathe perations; Milling machine operations; Dynamic tool path ; Cad; Cam; Canned cycles; Grooving; C axis operations;
