Topic: CNC Internal Corners
A simple CNC design tip:
Avoid sharp internal corners.
Why?
Because CNC cutting tools are round.
Sharp corners require:
- Smaller tools
- More machining time
- Higher cost
Adding a proper radius can:
✓ Reduce machining time
✓ Improve tool life
✓ Lower cost
Design with manufacturing in mind.
