9 Machining operations: Before machining the part, operation order must be determined and clamping method selected. For this component we will machine all operations in a vice leaving the outside profile last, which will be machined in a dedicated fixture. Machining Operations are as follows: Machining Operation 1 Facing 2 Contour 3 Circle Mill 4 5 Simple drill - no peck Peck drill - full retract 6 Circle Mill 7 Pocket 8 Pocket 9 Contour Tool Type Face Mill End Mill End Mill Spot Drill Drill End Mill End Mill End Mill End Mill Tool Description 2" Face Mill 3/4 FLAT ENDMILL 1/4 FLAT ENDMILL 1/2 SPOTDRILL NO. 36 DRILL 3/4 FLAT ENDMILL 1/4 FLAT ENDMILL 1/4 FLAT ENDMILL 1/2 FLAT ENDMILL Operation Comment FACE TOP OF STOCK MILL TOP FACE FOR BOSS CIRCLE MILL.750 DIA.

15 Select Verify Selected Operations Select Machine ENGI 7928 Computer Aided Engineering, Memorial University C. Koenig 15

16 Top of stock has been faced.025 Use Verify to check the part is being machined using the correct tool, toolpath direction, to appropriate depth cuts, rough cuts, & finish cuts. Select all operations, Verify, Select the Simulate Tool & adjust settings for Quality & Speed etc. Try using Backplot which displays toolpath, rapid moves, moves from feed plane and depth moves. Select all operations, Backplot, expand dialogue box, select Info for Cycle Times ENGI 7928 Computer Aided Engineering, Memorial University C. Koenig 16

17 Cutter rotation and cutter travel direction: When conventional machining on manual milling machines we generally feed the part against the direction of the cutter, referred to as conventional milling. When CNC machining we are generally working with a more rigid machine. If the part is rigidly held in by vice/fixture we will feed the part in the direction of the cutter know as climb milling. When working in Mastercam the tool looks like it is moving, even though in reality we know the CNC machine table is moving. Therefore, to ensure we are climb milling, remember the tool in Mastercam will move in a clockwise direction on an outside profile and counterclockwise direction on an inside profile (Clockwise outside- Counterclockwise inside).
