Computer-Aided Design Project
Laser-Cam Design Challenge
Design a two-cam mechanism that will trace a laser along the first letter of your name
Part 1: Path Tracing
Generated a list of (x,y) coordinates that trace out the first initial of my name. Plotted the coordinates versus i.
Part 2: Cam Profile Generation
Wrote MATLAB script that generated a function that resulted in a laser-pointer position at any given rotation. Plotted cam-profiles.
Part 3: SolidWorks
Imported design to SolidWorks and laser cut the cams from profile generated.
The Cam in Action
To create the lightest structure possible that can withstand a weight of 1 kg.
3D printing a prototype
First prototype (6g). Changed the design so stress is less spread out and reduces buckling.
After designing the prototype on Solidworks, I used topology optimization in ANSYS Workbench to create future iterations. It allowed me to find sections in the prototype that would not contribute to handling the load and therefore could be trimmed. Final product became 2.6 g in weight and was the third lightest structure in the competition.
