The final design and machining project was biomimicry. I designed and fabricated a biomechanical heart. The mechanism is called Tourbillon and it is a clockwork mechanism. This includes a heart-shaped centerpiece that rotates with a gear driven by the loaded coil leaf spring. The shaft is supported between two ruby bearings. I designed all the parts on SolidWorks 2023 and machined them using manual and CNC lathe, CNC Mini mill, and Prototrak. The materials used were brass, aluminum, and steel.

I designed and machined all the lathe parts for turning and created CAM files for the mini mill.
