Gooseneck Mortise and Tenon With Stub Tenons.

My goal this week was to create 'gooseneck mortise and tenon with stub tenons'. I accomplished this by using softwares such as Rhino and Carbide Create, and later, executed it with a Shapeoko CNC machine. The wood I was using had a thickness of 18 mm and the End Mill's diameter was 6.35 mm.

The first step of my project was to 3D model it in Rhino. Initially, I made curves that resembled my shape, and I did this using various Rhino features such as join, fillet curves, move, copy, etc. Once I created a basic shape of my joints, I went in with the fillet tool to create softened edges. After getting my curves, I went in with an extrusion to see a 3D model of my work. Once I did this, I used BooleanDifference to get my cuts the exact measurement I needed. I created a bigger 3D shape to cut my joints with, while making sure I get the same measurement cuts on each side.

I exported my .dxf file from Rhino, so I am able to open it in Carbide Create and start my cutting. I have attached the file.

I started with locating the tool on the edge of the board, so it can cut accurately and know where the board starts. Once it was all set up, I was ready to go.

Due to the fact that the machine cut out rough work, I went in with the sanding machine to be able to achieve smooth edges and clean work. Due to the fact that I made a small error with one of my curves, I used sanding in order to make it able to fit in one another.
