Institution:

Northern Maine Community College

Subject:

Description:

2 class hours, 2 lab hours Designed to provide students with an introduction to CAM software. Emphasis will be on creating 2 1/2 -axis CNC Milling operations: l Facing - regular or irregular profiles, with or without islands and pockets, using conventional, climb and alternating zigzag machining patterns l Pocketing - regular or irregular profiles with an unlimited number of sub-pockets and islands using spiraling, concentric-in or concentric-out patterns, with unidirectional or bidirectional machining to perform climbing or conventional cutting with roughing, wall-finishing and floor-finishing options. l Contouring - profile cutting for roughing, slotting, semi-finishing and finishing straight or tapered walls with constant or variable cutting depths. l Hole making - drilling, boring, tapping and other pointto- point machining cycles. l Spiraling - machining circular pockets and bores with concentric-in and concentric-out cutting as true spiral or tangent arcs. l Library standard tools - develop a tool library to include spot drills, drill, taps, finish end mills and roughing end mills. l Post processing - convert files to standard G&M codes using a variety of posts for use on CNC Milling Machines.
