The purpose of this project is to create a wooden name plate using the 3-Axis CNC Router in the KRLL shop. From this project, we learn how to use new CAD programs such as Aspire, and learn how to use shop tools such as the CNC Router. Additionally, we get to practice our skills on the Chop-Saw and renew other tertiary shop knowledge.
Inspire - The purpose of this project is to allow students to learn a new CAD program/design base, and to practice using new shop tools, as well as renewing our knowledge of other shop tools
Create - During the course of this project, we will create a wooden name plate (11"x5"x0.75")
Release -
The primary material used in this project was a piece of plywood with dimensions 12"x6"x0.75". This wood was cut from a larger piece of wood measuring 48"x6"x0.75".
This project utilized the Chop-Saw and the CNC Router.
The Chop-Saw was initially used to cut the 12"x6"x0.75" pieces to length from a larger 48"x6"x0.75" piece of wood.
The CNC Router was used to carve the name-plate designs onto the 12"x6"x0.75" piece of wood (carved name, border outlines) and to cut out the name-plate from the 12"x6"x0.75" piece of wood.
This is a video of the CNC router that we used during the manufacturing process.
We used the program Aspire to create the CAD for our signs, as well as to generate the g-code to run on the CNC Router.

This is our final name sign. It's relatively simple, but there are some processes that I would like to perform on it to hopefully improve it's appearance. First, I would like to spray paint it to turn it into a more vibrant color. After, I would like to fill all of the negative geometry with some epoxy.
One of the big challenges that I faced when making this project was learning how to use a new CAD program, Aspire. I've never worked with Aspire before, but given the instruction manual designed for this class, it was quite simple to figure out (I don't know if I could create a project on my own quite yet though).
Another one of the challenges that I faced during this project was the generation of G-Code. Generating G-Code is something that I have never really worked with, as during the 3D printing process, the slicer does all the work to generate the G-Code. Having to integrate the usage of different toolheads on different paths was a new idea to me. Luckily, with the guidance of my Engineering 3 teachers (Mr. Yamada-Hall and Mr. Wilhite), I was able to learn the basics of G-Code generation and usage.
Learning how to properly setup and run the CNC Router was another challenge in itself. From learning how to home the Z-axis to breaking the X and Y Homing point, this process was difficult and had many issues along the way. With the guidance and skills of Mr. Yamada-Hall, myself and my peers were able to understand the process of setting up the CNC Router.
