This three-year, $298,980 Project Grant from the National Science Foundation's Division of Civil, Mechanical, and Manufacturing Innovation, under the Engineering (47.041) federal grant program, supports research at the University of North Carolina at Charlotte related to advanced manufacturing processes for complex optical elements. The research aims to test the hypothesis that material removal mechanisms change at increased cutting velocities when single point diamond machining brittle single crystal materials such as germanium or silicon. Ultra-precision diamond machining experiments will explore the effects of higher cutting speeds. The study will quantify dynamic forces, chip morphology, and potential material phase changes under different conditions. Surface and subsurface characterization will also be performed. Insights gained from this work have the potential to enable more cost-effective manufacturing of freeform optics with applications in thermal imaging, solar energy, healthcare, and other sectors critical to the U.S. economy.
