For the first assignment on the big CNC, Nick Gregg and I decided to work together again.
We initially set out to route the same form we hand routed but were quickly overwhelmed when setting pocket directions on the CAM.
We chose to take one form from the many and add some text to explore the many ways the router can be used. As detailed at the end of the documentation, we were unsuccessful in routing out the whole circle.
We attribute this to the thickness of the region that wasn't cut through — the measurement taken prior to milling was 0.635 — the exact depth that we were cutting (as specified through CAM’s “ cut through” menu — 0.05 depth.
At that point we debated setting the zero origin z slightly lower and re-starting the file.
We decided against this in fear of damaging the bit. This did bring up the question: what is the proper procedure when this situation happens?
