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.

该补助金提供资金，以支持在嵌入式热管技术中建立理论基础和知识库的研究，以消除在加工行业中使用切削液。 该研究项目采用了一种新的传热概念，用于环保型刀具设计。本研究计划将进行以下研究：（1）切削刀具中嵌入式热管系统的表征;（2）热力学和传热有限元分析，以预测特定切削过程的温度分布;（3）评价嵌入式热管的性能，用于刀具磨损分析。切削耙刀片、热管容器、芯结构和工作流体是调节温度分布的设计参数。拟议的研究将导致传热行为的预测模型的发展，和实验研究和预测建模的刀具磨损，由于嵌入式热管在切削刀具在加工过程中。这些研究结果将有助于工业上的干式加工，本研究的影响将促进使用热管的温度控制优化，以实现工艺生产率和环境意识之间的平衡。然后，该模型可以用于选择实验条件进行探索，解释实验结果，并最终指导工业刀具设计干加工。 最后，该计划的研究成果将通过课程开发，少数民族参与联盟，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的跨学科活动与教育相结合。
