CNC - Week 8

Assignment: Make something big using CNC machine

Pocket milling in wood

That explain why the sacrificial was in such a bad shape: users compensate their Cut-Through-All machining by adding extra mm in the depth machining target.

The source files for the wood and aluminium milling can be found in this folder on gitlab.
The essential fabrication file are the:
