STTR Phase I: Modulation-Assisted Deep Hole Drilling of Micro/Meso-Scale Biomedical Components

该小企业技术转让（STTR）第一阶段项目将开发调制辅助加工（MAM）技术的创新应用，以提高高性能生物医学部件生产中微/中尺度特征深孔钻削的生产率。一个原型过程将被证明，它可以很容易地实现在现有的计算机控制的艾德机器。在这个过程中，一个受控的低频振动（调制）叠加到加工过程中，产生一系列离散的切削事件，这些事件通过调制参数以显著的有效性进行控制，从而轻松去除切屑。该工艺还将提高润滑的有效性，使加工能够在最少使用切削液的情况下进行。当在适当的框架中实施时，所提出的技术将产生一类高效，清洁的加工工艺，这些工艺将影响生物医学部件制造之外的应用，以及航空航天和汽车行业。预计减少切削液的使用将使该工艺对环境友好。与大学的合作将为学生提供良好的教育和培训机会。

This Small Business Technology Transfer (STTR) Phase I project will develop an innovative application for modulation-assisted machining (MAM) technique to increase the productivity of deep-hole drilling of micro/meso-scale features in the production of high-performance biomedical components. A prototype process will be demonstrated thayt can be easily achieved on aexisting computer-controll;ed machines. In this process, a controlled, low-frequencty vibration (modulation) is superimposed onto the machining process, creating a series of discrete cutting events that are controlled with remarkable effectiveness by the modulation parameters, leading to easy chip removal. The process will also enhance the effectiveness of lubrication, enabling the machining to be performed with minimal use of cutting fluids. When implemented in the appropriate framework, the proposed technology will result in a class of highly efficient, clean machining processes that will impact applications above and beyond the biomedical component manufacturing, to aerospace and automotive sectors. The anticipated reduction in the use of cutting fluids will make the process environmentally friendly. The partnership with the University will provide students excellent opportunity for education and training.
