These are the steps that I took to complete my seventh ENGI 210 Project: CNC Machining an object out of wood.
Step 1: Deciding on a design to CNC
The first step of this project was to choose a design to cut out of a block of wood using the CNC machine. I selected a capybara design from The Noun Project, and downloaded the file as a SVG. file.

Step 2: Modifying file for Nomad 3
Next, I imported the SVG. file into Carbide Create to modify for the Nomad 3. I inputted the dimensions of my stock and scaled the design to fit within the wood. I created two tool paths: the first to carve the capybara design at a depth of 0.05in and the second to cut out the outline of the capybara through the wood.

Step 3: CNC Machining on Nomad 3
Finally, I uploaded the tool path to Carbide Motion to CNC machine. I initialized the Nomad 3 and used the probe function to zero the coordinates around my stock wood piece. I ran into little to no problems throughout the CNC machining process and my piece was complete in around 20 minutes. This process was repeated twice to create 2 wooden capybara cutouts.

Cost Analysis
- 2x Wood Stock = $2.00
- Labor: 2 hours x $15/hour = $30
Total = $32.00
