Problem:
Redesign the thermodynamics class’ stirling engine mount for better machinability, lower cost, and/or better manufacturability then cast the part at a local foundry.
Final Design Description:
The design was based on the Thayer School emblem with small arrows showing where the students need to machine the part (mill and drill for the attachment of the engine), thus improving machinability by reducing the machine shop time (the drawings are not extremely clear). The rays in the first design came to a point but had to be expanded in order for the cast to work. With the tree cut-out and a thinner base, this design also uses less material and therefore is cheaper to make than the original design. The detailed design of the part was not intended to improve its manufacturability.
It was then placed in the engineering school's display case for student work.
