This award supports fundamental research on polishing single-crystal diamond as a means to fabricate diamond micro-endmills. The research objective is to determine the effects of polishing parameters, including polishing speed, polishing depth, abrasive grain size and crystallographic orientation of the polished surface, on the process outcome, including average polishing rate, polished surface roughness, and polishing tool wear. The specific approach will include conducting systematic experiments through the design of experiments technique, developing a simplified model of the polishing process, and evaluating the fabricated diamond micro-endmills by micromachining various features on different materials. The educational objectives are to enhance the future manufacturing workforce, and to improve the existing manufacturing curricula. The specific approach will be to involve the undergraduate and graduate students, especially from the underrepresented groups, in this research, and to complement the existing micro/nano-manufacturing course with the knowledge gained in this project.If successful, the benefits of this research will include facilitating efficient and effective fabrication of three-dimensional micro parts and features for medical, consumer products, military, and electronics industries. Micromachining operations will be enabled in a more predictable fashion. Common problems such as erratic forces, short tool life, inferior surface finish, and burr formation will be minimized, thereby eliminating some of the most profound obstacles that prevent further development of micro-manufacturing. Close collaboration with industry will enable rapid transfer of research/technology to industry. Since micro-manufacturing is viewed as one of the emerging manufacturing technologies, this research is also critical for the United States to retain its competitiveness in manufacturing. Furthermore, the knowledge gained from this work will impact emerging applications of diamond in various fields.

该奖项支持抛光单晶金刚石作为制造金刚石微型立铣刀的手段的基础研究。研究的目的是确定抛光参数，包括抛光速度，抛光深度，磨粒尺寸和抛光表面的晶体取向，对工艺结果，包括平均抛光速率，抛光表面粗糙度和抛光工具磨损的影响。具体的方法将包括通过实验技术的设计进行系统的实验，开发一个简化的模型的抛光过程，并评估制造的金刚石微立铣刀通过微加工不同的材料上的各种功能。教育目标是提高未来的制造业劳动力，并改善现有的制造业课程。具体的方法是让本科生和研究生，特别是来自代表性不足的群体的学生，参与这项研究，并利用本项目中获得的知识补充现有的微/纳米制造课程。如果成功，这项研究的好处将包括促进医疗，消费品，军事，和电子工业。微加工操作将以更可预测的方式实现。常见的问题，如不稳定的力量，短刀具寿命，劣质表面光洁度，毛刺的形成将被最大限度地减少，从而消除了一些最深刻的障碍，阻止进一步发展的微型制造。与工业界的密切合作将使研究/技术快速转移到工业界。由于微型制造被视为新兴制造技术之一，这项研究对美国保持其制造业竞争力也至关重要。此外，从这项工作中获得的知识将影响钻石在各个领域的新兴应用。
