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).

普渡大学的创新合作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。通过在切削刀具上叠加低频/小幅度调制，调制辅助加工可产生小的、离散的切屑，同时显着减少加工中的摩擦和能量耗散。调制辅助加工研究平台将扩大该技术的应用范围，从当前的固定钻孔配置（通过先前的 NSF 支持开发和商业化）扩展到钻孔、车削、镗孔、套料和相关工艺中的广泛旋转刀具应用。优点包括生产率提高两倍以上，以及刀具磨损和加工排放量大幅减少。同样重要的是，该平台将有助于开发稳健的方法，以实现离散产品制造领域中旋转工具和机器的动力传输。这项研究的更广泛影响是提高生产率、提高产品质量、更多地使用传统加工无法经济地制造的高性能合金，以及大幅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具有成本效益的路线，并改进骨科手术的切割技术。该项目启动时的合作伙伴包括普渡大学（工业、材料和电气与计算机工程学院）、M4 Sciences LLC（印第安纳州西拉斐特；II 类小型企业）和 American Micro Products（俄亥俄州巴达维亚；I 类小型企业），均为知识增强合作伙伴；并得到其他合作伙伴的补充：康明斯公司（印第安纳州哥伦布市；大型企业）、山高刀具（瑞典法格斯塔；大型企业，现属于山特维克公司）、普渡兽医学院（印第安纳州西拉斐特市普渡大学的一部分）以及罗彻斯特理工学院国家聋人技术研究所（纽约州罗彻斯特；非营利组织）。
