As a group, we began by completing the lab's safety training to ensure we followed all necessary precautions while working with the machines. We then tested spindle runout and alignment to confirm the machine’s accuracy. After properly fixturing the material, we experimented with different speeds and feeds to determine the most effective settings. Finally, we tested our toolpaths to ensure smooth operation and reliable results during the actual machining process.
😄 Here's a fun mental image of us around the CNC.

For this assignment, the goal was clear: design, mill, and assemble something big using computer-controlled machining. I wanted to create something that was not just large in scale but also practical and relevant to my daily life. That's how I came up with the idea of an adjustable computer stand, a piece I could use both for my Fab Academy tasks and regular work sessions.
My initial idea was to design a portable and adjustable computer stand that could adapt to different working positions. I often work long hours, and comfort and flexibility are key. I also wanted the stand to be easy to disassemble for transport or storage.
The first step was to explore what others had done. I browsed Pinterest and eventually found this image that captured the general look I was going for. Although there were no measurements, the structure gave me a solid visual guide for my own interpretation.
Using SolidWorks, I designed the adjustable stand. The structure was fairly simple two main side legs with vertical slots and a horizontal platform that could slide into different positions. I also made sure the parts would fit together without glue or screws (press-fit), which aligns with the Fab Academy's focus on digital fabrication.
Before milling, I assembled the parts virtually in SolidWorks to check for any interferences or fit issues. The design looked good, so I exported the 2D drawings as DXF files, ready for CNC processing.
I used VCarve to prepare the toolpaths and arrange the layout for cutting. After that, I set the origin and controlled the milling process using the ShopBot Control System Interface.
The milling went smoothly, and all parts came out clean. I sanded the edges, assembled the pieces, and was satisfied to see the stand working just as expected — strong, stable, and adjustable.
