SBIR Phase II: Micro-quantity Internal Cooling (MQuIC) of Cutting Tools for Increased Productivity via Micro-ducts

这项小型企业创新研究(SBIR)第二阶段的研究旨在开发具有内部微几何特征的刀具并将其商业化，以便为刀具-芯片接触区提供相对直接和局部的冷却。拟议的创新是(I)结合微尺度的内部特征和(Ii)能够提供这些改进的刀具刀片的大批量制造的生产工艺。在加工过程中使用涂层进行有效冷却的传统方法效果有限，但该方法被认为提供了一种新的方法，为加工难加工材料提供内部冷却机制。如果成功，这项技术将在精进给难加工材料的加工过程中实现更长的刀具寿命，这将对DTM合金的加工产生巨大影响。由于机械加工过程中的有效热传递，只需最少的冷却剂使用，这项研究将导致新的制造方法，并对环境污染产生积极影响。

This Small Business Innovation Research (SBIR) Phase II research aims to develop and commercialize cutting tools with internal micro-geometric features to provide relatively direct and localized cooling of the tool-chip contact zone. The proposed innovation is (i) incorporation of micro-scale internal features and (ii) a production process that can provide high-volume manufacturing of these modified cutting tool inserts. Conventional approaches of using coatings for effective cooling during machining have limited effectiveness, but the proposed approach is claimed to provide a novel method of providing internal cooling mechanism to machine difficult-to-machine (DTM) materials. If successful, this technology will enable better tool-life during the machining of hard-to-machine materials at finish feeds, which can have tremendous impact for machining of DTM alloys. By requiring minimal coolant use due to effective heat transfer from machining operation, the research will lead to new manufacturing methods with a positive impact on environmental pollution.
