Subtraction Week 5: CNC Joinery

For this week’s assignment, I decided to CNC a mortise & tenon joint. This joint is in preparation for my midterm project.

First I started by drawing the CAD with a tolerance of .02 inches. These pieces should nestle together & also slot together into a rosette.

Setup up the CAM then ran on the CNC. 

I filed the inner corners so that the tenon could fit into the mortise. Unfortunately, since the thickness of the 1″ MDF used was more than the 1″ wood that I based the measurements off of, so the joints did not fit together well.
