For this assignment, I decided to make a cutout of my home state, South Carolina, with its flag on top. In order to do so, I downloaded a svg file of South Carolina with the crescent moon and palmetto tree on top. I then imported into Carbine Create and followed the instructions within the homework document. I set a pocket cut between the state outline and the moon & palmetto tree, followed by a contour cut of the outline with no offset. After viewing the G-code simulation of my part, I noticed several issues along the coast and tree. Due to the fine detail of the svg, especially along the coast of SC, the CNC would have significant difficulty cutting it exactly, resulting in a severely deformed/altered shape along certain spots. In order to address this issue, I edited my svg by removing a vast amount of nodes to simplify the overall shape and cut. Once finished, I then began setting up the CNC machine and started cutting.

After cutting both pieces, the overall pieces were good; however, the edges were decently rough. I hand sanded the edges of both pieces by hand using 100 and 180 grit sandpaper. I then used an orbital sander with 320 to sand the faces of both pieces.

Since the state’s flag is blue with a white moon  and a palmetto tree, I wanted to paint the state blue with the moon and the palmetto tree white. However, I was initially unsure of how well I could cover the moon and tree without impending on the state itself, due to their size and small features/edges. I decided to try and cover the moon and tree of one piece as best as I could to see how good it would be. I was able to pretty effectively cover the moon and tree, including their sides and edges/cuts, without impending on the state itself. However, it was to some extent tedious, tricky, and time consuming that I decided to simply cover the other piece as well.

I then spray painted both pieces blue and let them dry for 24 hours. 

Afterwards, I then removed the tape and was happy with the outcome. I then sanded the moons and trees again by hand using 320 grit (there was residue and a little bit of smudge from the tape). Finally, I applied beeswax to the moon and tree to create a more finished look.

Materials

• Two 5” x 3” x .69” Wood Pieces
• Blue Spray Paint
• Beeswax

Cost Estimate

• Wood: After looking through Home Depot, I would estimate that the total wood would cost around $5
• Spray Paint: $7
• Beeswax: $10
• Labor: Since my pieces are South Carolina, I based my hourly wage on SC’s minimum wage, which is $7.25/hour. Excluding wait time and time spent fixing the machine, I spent roughly 5 hours working on the diamonds. Therefore, the total labor cost would be $36.25
• Total Cost Without Machinery: $58.25
• Machinery (Shapeoko Pro XXL): $2400 (educated guess)
• Total Cost: $2458.25
