4. Computer Controlled Cutting¶
Solo Assignment¶
Vinyl Cutting Assignment¶
I chose the NASCAR 2017 logo as my sticker. I like motorsports, and this logo is visually clean while still requiring multi-color layering.
Demonstrating Design Software Use¶
I opened the logo in CorelDRAW and used Trace Bitmap to convert the raster image into editable vector paths.
After tracing, I separated each color into its own vector layer rather than simply importing the final JPG. This allowed me to adjust path accuracy and ensure clean edges.
I then imported the vector file into Silhouette Studio. Inside the program, I:
- Used the “Trace” tool again to verify contours,
- Cleaned anchor points,
- Divided shapes into individual cut jobs for each color.
Once the paths were finalized, I loaded the correct vinyl color, selected the corresponding shapes, and performed each cut. After cutting, I weeded excess vinyl and assembled the pieces on transfer tape.
Color layers used:
Parametric Design¶
We learned parametric modeling in Fusion 360. I referenced Angelina Yang’s parametric kit as inspiration.
I began by creating three core components: a rectangle, a polygon, and a 120° connector.
I defined all key parameters in the “Change Parameters” menu (height, width, slot depth, slot thickness, polygon sides).
I measured my cardboard thickness (≈3.4 mm) and added kerf (≈0.3 mm), setting my slot width to 3.7 mm. Slot length was set to 5 mm. I then sketched each part with fully constrained geometry and slot features.
I exported the vectors as .dwg to CorelDRAW.
Using the laser cutter’s recommended cardboard settings, I produced the pieces.
The Kit¶
The kit worked as expected. I would increase fillet sizes and deepen notches for a tighter assembly.

Group Assignment¶
Group Site: https://fabacademy.org/2025/labs/charlotte/assignments/week04/
My contributions included:
- Kerf test
- Speed, power, and frequency test
- Focus test
Reflection¶
Group Work: Working with the group made the machine-parameter tests much faster. Comparing kerf measurements and material behavior across multiple testers helped us identify more reliable cutting settings. The group page reflects a combined understanding of the machine’s capabilities.
Individual Work: Completing the vinyl and parametric design assignments forced me to document each step instead of only showing final outputs. Demonstrating my workflow in CorelDRAW, Silhouette Studio, and Fusion 360 helped reinforce good documentation habits and clarified how design choices affect fabrication results.
