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.
- 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
This course meets live each week in a virtual classroom using video conferencing technology where the instructor and students can all see and hear each other.
