Investigation of Embedded Heat Pipes in Cutting Tools for Dry Machining

这笔赠款支持在嵌入式热管技术方面建立理论基础和知识库的研究，以消除机械加工行业中切削液的使用。本研究项目采用一种新的传热学概念进行环保型刀具设计。本研究项目将进行以下研究：(1)刀具内嵌热管系统的表征；(2)热力学和传热学有限元分析，以预测特定切割过程中的温度分布；(3)用于刀具磨损分析的内嵌热管的性能评价。切割前角刀片、热管容器、芯子结构和工作液是调整温度分布的设计参数。这项研究将导致建立热传递行为的预测模型，并对刀具在加工过程中由于嵌入热管而导致的刀具磨损进行实验研究和预测建模。研究结果将有助于干式加工在工业上的应用。本研究的影响将有助于优化使用热管的温度控制，以达到工艺生产率和环境意识之间的平衡。这些模型可以用来选择实验条件来探索，解释实验结果，并最终指导干式加工的工业刀具设计。最后，该计划内的研究成果将通过课程开发中的跨学科活动、少数群体参与联盟、高中联合研究计划、大学/行业研讨会和会议以及网络信息中心与教育相结合。

This grant provides funding to support research in building the theoretical basis and knowledge base in embedded heat pipe technology for elimination of the use of cutting fluids in the machining industry. This research project adopts a new heat transfer concept for environmentally conscious cutting tool design. This research project will conduct the following investigations: (1) characterization of the embedded heat pipe systems in cutting tools; (2) thermodynamic and heat transfer finite element analyses to predict the temperature distribution of the specific cutting process; (3) evaluation of the performance of the embedded heat pipe for tool wear analysis. The cutting rake insert, heat pipe container, wick structure, and working fluids are design parameters to adjust the temperature distribution. The proposed research will lead to the development of predictive models for heat transfer behavior, and experimental investigation and predictive modeling of the tool wear due to the embedded heat pipes in cutting tools in machining processes. The outcome of these studies will be useful for dry machining in industry.The impact of this research will facilitate the temperature control optimization in the use of the heat pipe in achieving a balance between process productivity and environmental consciousness. The models can then be used in selecting experimental conditions to explore, to interpret the experimental results, and, ultimately, to guide industrial tool design for dry machining. Finally, the research results within this program will be integrated with education through interdisciplinary activities in curriculum development, Alliance for Minority Participation, high school joint research programs, university/industry seminars and conferences, and web information center.
