CNC Machining Basics (Virtual)
#: LVON-1017   ID: 228   Section: 1028  

This live online training course is offered by a collaboration of Minnesota State colleges.

This 6-week course is designed to give students the fundamental knowledge of how CNC Lathes and Milling Machines work. Each two-hour class session will have a mixed media format, combining lecture presentation with professionally made YouTube videos and machine brochures from various machine tool manufacturers.

Topics include the multi-plane Coordinate Systems, overview of standard CNC programming commands, machine maintenance, similarities and differences between machine models, work holding and cutting tools, and some details on machine setup activities. A short refresher on shop math (in particular, trigonometry) will also be covered, as this is essential for being a good machinist.

Course Outcomes: 

  • Understand the capabilities and basic operating concepts of typical CNC milling machines and lathes, including multi-axis systems
  • Identify the differences between single and multi-turret CNC lathes and understand how “live tooling” works
  • Know the standard EIA command codes (G, M, T, S, D, other functions)
  • Understand how a CNC machine is programmed
  • Learn common canned cycles
  • Read a CNC program and describe what the program is doing
