切削液传统上用于去除金属切削过程中产生的热量。在切削刀具外使用切削液可能导致环境污染、健康危害和其他重大负面后果。内冷切削刀具因此是理想的和有前途的加工行业。本文基于拓扑优化和CFD仿真设计了一种内冷车削刀具，然后引入力学和热传导分析模型中的固体各向同性材料惩罚（SIMP）模型，对刀具流道进行了设计和优化。利用传统刀具的力学和热分析结果，建立了完善的内冷刀具拓扑优化模型。与传统刀具的性能相比，新设计的刀具可以大大降低热量，并在最小变形的情况下达到最高温度。通过流固耦合热分析，模拟了不同流速下新配置刀具的热场分布、最佳流速、最大制冷量和最高刀具温度等关键性能。
Cutting fluid is traditionally used to remove the generated heat during the metal cutting process. Employing cutting fluid outside the cutting tools may result in environmental pollution, health hazards, and other significant negative consequences. Internally cooled cutting tools are thus desirable and promising for the machining industry. In this paper, an internally cooled turning tool is designed based on topology optimization and CFD simulation, followed by solid isotropic material with penalization (SIMP) model imported in mechanical and heat conduction analyzing models for the tool flow channel design and optimization. The mechanical and thermal results are utilized on a traditional tool to formulate a sound topology optimization model of the internally cooled tool. In comparison with the performance of the traditional tool, the newly designed one can greatly reduce the heat as well as the maximum temperature with minimum deformation. Key performance of the newly configured tool, including thermal field distribution, best flow speed, maximum cooling capacity and maximum tool temperature, are simulated under different flow speeds by fluid-structure interaction thermal analysis.
