For the CNC assignment, I decided to create a mancala board that I could use to play with my friends.

To begin, I created an .svg file for the mancala board in Adobe Illustrator. I then imported this into Carbide Create and programmed pocket cuts for all the pits in the board. These were set to 0.150″ deep. I also created a contour path to cut out the rounded edges of the mancala board. Lastly, I added tabs so the piece could still stay in place after the contour cut was made. The result is shown in the image below.

Next, I began to cut out the design using the Nomad CNC machine as seen in the picture below.

You can see the result below.

As you can see, this required significant post-processing. I cut off the edges using the bandsaw as seen in the image below.

I sanded using various grits as fine as 220. I also went over my piece with the orbital sander. After vacuuming all the sawdust off my piece, I coated it with finishing oil. The final result is shown below.

Later, I plan to assemble the two halves using a hinge to make a fully functional board.

Here is a picture of my last clean workspace after spray painting.
