SKCN 260 - CNC Multi Axis

Credits: 4
Instructional Contact Hours: 4

Introduces and demonstrates concepts for multi axis machining techniques beginning with 3 plus 2 axis utilizing planes then advancing to true 5 axis machining. Import engineering drawings and electronic CAD files into CAM software to perfect geometry and tool path routines, then output G-code specific to the multi-axis machine. Individual and/or team assignments will focus on complex applications and the true efficiency of multi axis machining. Credit may be earned in CNC 260 or SKCN 260 but not both.
