  • 1. 368 Players Ridge Rd  Hickory NC 28601  (828)244-3914  rhamby@uncc.edu Device for Ruling on Freeform Optical Surfaces __________________________________________________________ Project: To Designed, Developed, and Produced a working Device for the Ruling on a Freeform Optical Surface. o Presented weekly reports with group members while learning how to communicate fluently within a group. o Utilized independent time management to complete project, going above and beyond the scope of the project in order to produce results. o Independent research leading to the potential of successful outcome RESULTS Examined with Scanning Electron Microscope Utilized Kistler Dynamometer to produce Figure 1 of force desired relative to moment arm application Figure1 Developed as step input of precise weight application resulting in piecewise function determined empirically. 40 Hz was used as cutoff to eliminate frequencies from surrounding walls. Sensitivity of Kistler dynamometer was 1 N/V for testing. Resulting Conclusion: Prove of concept allowing for continuation to Senior Design Project. Displayed ability to make rulings at low force needed for rulings on free form optical surfaces.
