STTR Phase II: Modulation-Assisted Deep Hole Drilling of Micro/Meso-Scale Biomedical Components

这个小型企业技术转移（STTR）二期项目旨在开发一种调制辅助加工（MAM）系统，该系统具有微/中尺度生物医学部件深孔钻削的新功能。该系统是围绕一个新设备构建的；为计算机数控（CNC）机床开发的附件。这种新设备在加工过程中叠加了低频正弦调制，从而控制了切屑的形成和易于处理，增强了刀具与切屑接触的润滑，降低了能耗，并有可能减少刀具的磨损。如果在适当的系统框架内实施，预计深孔钻井过程的生产率和效率将得到前所未有的提高。该项目更广泛的影响/商业潜力将使MAM技术在生物医学部件制造和汽车和航空航天流体系统制造中的相关应用商业化。辅以强有力的教育和培训计划。通过推动一类清洁加工工艺的发展，减少废水和能源消耗，提高效率，该项目将影响离散产品行业的可持续制造，并带来广泛的社会效益。

This Small Business Technology Transfer (STTR) Phase II project aims to develop a Modulation-Assisted Machining (MAM) system with novel capabilities for micro/meso-scale deep-hole drilling of biomedical components. The system is structured around a new device; an accessory developed for computer numerically controlled (CNC) machine tools. This new device superimposes a low-frequency sinusoidal modulation onto machining processes enabling controlled chip formation and easy disposal, enhanced lubrication of tool-chip contact, reduces energy consumption, and, potentially, a reduction in tool wear. When implemented in the appropriate system framework, unprecedented increases in productivity and efficiency of deep-hole drilling processes are envisaged. The broader impact/commercial potential of this project will be commercialize MAM technology in manufacturing of biomedical components and related applications in automotive and aerospace fluid systems manufacturing. Complemented by a strong education and training program. By driving the development of a class of clean machining processes with reduced effluent streams and energy consumption, and improved efficiency, this project will impact sustainable manufacturing for the discrete products sector, with broad societal benefits.
