Oscillating Air Motor
Attention to detail and focus in machining is demonstrated in the best projects each year.
The Oscillating Air Motor is a major term project in Mech 139 first semester course, which introduces students to machining and fabrication. The air motor consists of seven individual parts, including: 0.5" diameter brass piston with a 1" stroke; 3.5" diameter, 0.5" thick aluminum flywheel of 200 kg mass (0.44 lb). The crankplate is made of brass, and mild steel is used for the base and cylinder (which houses the piston). Components are made with three different milling machines and three different lathes, each set up for specific procedures. An arbor press is used during assembly. In order to operate smoothly and under minimum air pressures, tolerances of ± 0.005" (five thousands of an inch) are required between moving parts.
Wankel Rotary Engine
A moving model of a Wankel Rotary Engine is the major term project in Mech 247 second year course. It consists of an aluminum body, rotor, offset shaft, and plastic planetary gears (plastic machined using a 0.032" diameter cutter). Students create parts and develop toolpaths using Mastercam. The class then produces a working model of the Wankel engine on the Haas CNC Mini Mill.
