STTR Phase I: Ultra-High-Speed Micro-Milling Machine

这项小型企业技术转移（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铣床，该铣床具有微主轴/电机组件以及原位计量传感器。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制造高精度三维（3D）产品，其尺寸范围从几十微米到几毫米。虽然微尺度技术在半导体和微电子领域已经建立了良好的基础，但对于制造涉及复杂3D几何形状和非硅材料高精度的产品来说，情况却并非如此。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。莫霍克创新技术公司与佐治亚理工学院合作，将开发一种独特的超高速精密微铣床，它将能够同时用于铣削（加工较软的金属）和磨削（加工较硬的金属和陶瓷）。所提出的微铣床的主要优点，除了最先进的原位测量，是通过超高速主轴的实施获得更高的精度，这将减少切削力和刀具振动。在第二阶段，提出的超高速精密微铣床将被进一步评估和修改，以演示各种行业的复杂零件的制造，包括国防，航空航天，医疗保健和能源。拟议的桌面系统的设计将考虑到可负担性、便携性和多功能性，以协助发展新的商业和工业以及高价值的工作。

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.
