This Small Business Technology Transfer (STTR) Phase I project is directed towards the design, development, and evaluation of a unique ultra-high-speed precision micro-milling machine with a micro-spindle/motor assembly along with in situ metrology sensors. The proposed micro-milling machine is an integral part of an overall micro-manufacturing system. Micro-manufacturing refers to the creation of high-precision three-dimensional (3D) products using a variety of materials and possessing features with sizes ranging from tens of micrometers to a few millimeters. While micro-scale technologies are well established in the semiconductor and microelectronics fields, the same cannot be said for manufacturing products involving complex 3D geometry and high accuracies in non-silicon materials. At the same time, the trends in industrial and military products that demand miniaturization, design flexibility, reduced energy consumption, and high accuracy continue to accelerate -- especially in the medical, biotechnology, telecommunications, and energy fields. Mohawk Innovative Technologies, in partnership with the Georgia Institute of Technology, will develop a unique ultra-high-speed precision micro-milling machine, which will have the capability of being used both in milling (for machining softer metals) and in grinding (for harder metals and ceramics). The principal advantage of the proposed micro-milling machine, besides the state-of-the-art in situ metrology, is the higher precision obtained through the implementation of the ultra-high-speed spindle that will decrease the cutting forces and thus tool vibrations. In Phase II, the proposed ultra-high-speed precision micro-milling machine will be further evaluated and modified to demonstrate the fabrication of complex parts for a variety of industries including defense, aerospace, healthcare and energy. The proposed desktop system will be designed with considerations of affordability, portability and versatility to assist in the development of new businesses and industries, and high value jobs.

该小型企业技术转让（STTR）第一阶段项目旨在设计、开发和评估一种独特的超高速精密微型铣床，该铣床具有微主轴/电机组件沿着原位计量传感器。所提出的微铣床是整个微制造系统的一个组成部分。微制造是指使用各种材料创建高精度三维（3D）产品，并具有尺寸从几十微米到几毫米的特征。虽然微尺度技术在半导体和微电子领域已经很成熟，但对于涉及复杂3D几何形状和非硅材料高精度的制造产品来说，情况并非如此。与此同时，要求小型化、设计灵活性、降低能耗和高精度的工业和军事产品的趋势继续加速，特别是在医疗、生物技术、电信和能源领域。Mohawk Innovative Technologies与格鲁吉亚理工学院合作，将开发一种独特的超高速精密微型铣床，该机床将能够用于铣削（加工较软的金属）和磨削（加工较硬的金属和陶瓷）。 所提出的微型铣床的主要优点，除了国家的最先进的原位计量，是更高的精度，通过实现超高速主轴，将减少切削力，从而工具的振动。在第二阶段，将进一步评估和修改拟议的超高速精密微型铣床，以证明为国防、航空航天、医疗保健和能源等各种行业制造复杂零件。拟议的桌面系统在设计时，会考虑到市民的负担能力、可携性和多功能性，以协助发展新业务和新行业，以及高价值的工作。
