This project was undertaken in my 3rd year in the 2.72 Elements of Mechanical Design class at MIT. Teams are tasked with designing and manufacturing a precision desktop lathe able to machine aluminium to a precision of 25 microns in a single semester.
On a scale this small, load bearing elements function more like pieces of rubber acting on each other, and a new respect for dimensional and geometric tolerances is quickly acquired.
At the end of the semester all teams compete against one another to machine a part to specified dimensions as precisely and quickly as possible.
