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)第二阶段项目旨在开发一种具有新能力的调制辅助加工(MAM)系统，用于生物医学部件的微细/中观深孔钻孔。该系统是围绕一种新设备构建的，这是一种为计算机数字控制(CNC)机床开发的附件。这种新设备将低频正弦调制叠加到加工过程中，实现了可控的切屑形成和轻松处理，增强了刀具-切屑接触的润滑，降低了能源消耗，并有可能减少刀具磨损。当在适当的系统框架中实施时，预计深孔钻探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/商业潜力将是将生物医学部件制造中的MAM技术商业化，以及汽车和航空航天流体系统制造中的相关应用。并辅之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开发，减少流出物和能源消耗，提高效率，该项目将影响离散产品部门的可持续制造，具有广泛的社会效益。

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.
