Dome Tester, Clark Bates, Nikolas M. Kulin
Williams Honors College, Honors Research Projects
We are reconfiguring and modifying the previously built dome tester to be more user friendly and mechanically applicable. This has a long-term goal of being a usable teaching tool for manufacturing education within the college of engineering and polymer sciences. The dome tester pushes a metal dome into a clamped sheet of metal to test its forming limits and where necking occurs. We have implemented a better method of viewing the sheet sample as it is being deformed, and improved measuring methods for the distance a sample is deformed. By introducing these changes in conjunction with improved documentation of the …

Grinding And Super-Finishing Test Machine Project, Michael Simon
Williams Honors College, Honors Research Projects
A research project in The University of Akron to study grinding and super-finishing of silicon nitride ceramic was initiated by Dr. Siamak Farhad and sponsored by the Timken Company, with the assistance of undergraduate students Michael Simon, Ryan Hosso and Mathew Rozmajzl. The study required analysis of forces and scratches generated during grinding processes of silicon nitride samples. A testing assembly was designed and constructed to record the forces generated during grinding and super-finishing of silicon nitride samples in a computer-numerical-control machine. Silicon nitride samples were subjected to desired grinding and super-finishing operations and all forces generated during the process …

Automated Runout Measurement Tool, Ethan Tisch
Williams Honors College, Honors Research Projects
A new measurement process and tool is to be developed to improve the existing method for measuring runout on the commutators of brushed DC product.
After an armature is manufactured, the commutator is inspected by placing the completed rotor assembly in one of several non-standard measurement fixtures. An indicator is then positioned on the commutator. A trained operator proceeds to rotate the armature while taking runout and bar-to-bar measurement at various positions along the length of the commutator.
This existing process is slow, costly, and unreliable. For these reasons, there is substantial economic pressure to develop a superior method for …
