Manufacturing Tip: CNC Internal Corners

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.
