- NC vs CNC
- CNC vs Manual
- Conventional vs. Unconventional
- CNC milling → Vertical
- N, F high | a low
- Ball nose
- Chuck vs. Collet - eccentricity
- Indexing box not needed
- Vise is problematic
- Magnetic vise
- Rotary table → 4 axis (not really needed)
- Between two centers
- Higher Diameter → Higher depth of cut
- Hardware
- Ball screw vs. Power screw
- Motors
- Fail-safe design for negative z axis
- Feed
- Free feed (run in, run out?)
- Cutting feed
- Tool magazine vs. manual (tool collet)
- Absolute (G90): from reference | Incremental (G91): from last point
- G code is for all CNC machines; not all motion functions are used
- 4 zero offsets for boosting productivity
- Preparatory functions
- CW → cutting edges of cutting tool
- M7 → pause
