PFI-BIC: Modulation-Assisted Machining

普渡大学的创新伙伴关系项目旨在充分实现调制辅助加工在离散产品领域的商业应用。通过在刀具上叠加低频/小振幅调制，调制辅助加工产生小而离散的芯片，同时显著减少加工中的摩擦和能量消耗。调制辅助加工研究平台将扩大该技术的应用范围，从目前的固定钻孔配置（通过先前的NSF支持开发和商业化）扩展到广泛的旋转工具应用，包括钻孔、车削、镗孔、钻孔和相关工艺。其优点包括生产率提高两倍以上，并且大大减少了刀具磨损和加工排放。同样重要的是，该平台将为离散产品制造部门的旋转工具和机器提供强大的电力传输方法的开发。这项研究的广泛影响是提高生产率，改善产品质量，更多地使用传统加工无法经济制造的高性能合金，并大大减少加工排放，并带来相关的环境效益。这些都是在高性能加工应用中实现调制辅助加工的结果。该平台还将为粉末材料制造提供新的成本效益路线，并改进骨科手术的切割技术。项目开始时的合作伙伴是普渡大学（工业、材料和电气与计算机工程学院）、M4科学有限责任公司（西拉斐特，印第安纳州；二类小企业）和美国微产品公司（俄亥俄州巴达维亚，俄亥俄州；一类小企业），所有这些都是知识增强合作伙伴；其他合作伙伴：康明斯公司（哥伦布市，大企业）、赛高工具公司（瑞典法格斯塔市，大企业，现为山特维克公司的一部分）、普渡兽医学院（普渡大学的一部分，西拉斐特市，印第安纳州）和罗切斯特理工学院国家聋人技术研究所（罗切斯特市，纽约州，非营利性）。

This Partnership for Innovation project from Purdue University is aimed at fully enabling the commercial application of Modulation-Assisted Machining in the discrete products sector. By superimposing a low-frequency/small-amplitude modulation on the cutting tool, Modulation-Assisted Machining produces small, discrete chips, while dramatically reducing friction and energy dissipation in machining. The Modulation-Assisted Machining research platform will expand the range of application of this technology from the current stationary drilling configurations (developed and commercialized via prior NSF support) to a wide range of rotating tool applications in drilling, turning, boring, trepanning, and related processes. Benefits include greater than two-fold increases in production rate, and large reductions in tool wear and machining emissions. Equally important, the platform will provide for development of robust methods for effecting power transfer to rotating tools and machines in the discrete products manufacturing sector.The broader impacts of this research are higher productivity, improved product quality, greater use of higher performance alloys that cannot be manufactured economically by conventional machining, and major reductions in machining emissions with associated environmental benefits. These are a consequence of enabling the implementation of Modulation-Assisted Machining across high-performance machining applications. The platform will also offer new cost-effective routes for powder materials manufacturing, and improved cutting techniques for orthopedic surgery.Partners at the inception of the project are Purdue University (Schools of Industrial, Materials and Electrical & Computer Engineering), M4 Sciences LLC (West Lafayette, IN; Type II small business) and American Micro Products (Batavia, OH; Type I small business), all Knowledge Enhancement Partners; complemented by other partners: Cummins Inc. (Columbus, IN; large business), Seco Tools (Fagersta, Sweden; large business, now part of the Sandvik Corporation), Purdue College of Veterinary Medicine (part of Purdue University, West Lafayette, IN) and the National Technical Institute for the Deaf, Rochester Institute of Technology (Rochester, NY; non-profit).
