冷却系统已成为缓解干切削过程中产生过多热量的有效方法。在本文中，我们研究了一种新型的内部冷却系统，独立于额外的机械附件，作为一种有前途的冷却替代方案。所提出的系统被设计为根据刀柄的几何形状创建的连接的“V”形内部流体通道。为了对所提出的系统的有效性进行定量评估，建立了一种新的数值方法。在该方法中，根据热力学推导了传热方程；通过解析建模确定了方程的参数。因此，可以根据出口温度高精度地估计切割温度。通过切削实验验证了所提数值方法的有效性。采用红外热成像仪测量刀具-芯片界面温度。基于经验模态分解（EMD）的自适应均值滤波器，推导出具有抑制噪声的平滑测量结果。实验结果表明，该系统可大幅降低测点温度（近30%），与数值模拟结果高度一致。所提出的冷却系统是智能刀具发展的前瞻性增强。
The cooling system has emerged as an effective way to alleviate the excessive heat generation during dry cutting processes. In this paper, we investigated a novel type of internal cooling system, independent of additional mechanical accessories, as a promising cooling alternative. The proposed system is devised as connected internal fluid channels of a-“V” shape created according to the geometric shape of the tool-holder. Enabling quantitative evaluation of the effectiveness of the proposed system, a new numerical approach is established. Within the approach, heat transfer equations are deduced according to thermodynamics; parameters of the equations are specified via analytical modeling. As a result, cutting temperatures can be estimated with high precision according to the outlet temperature. Moreover, a cutting experiment was carried out to verify the effectiveness of the proposed numerical approach. Tool-chip interface temperatures were measured using an infrared thermal imager. Smooth measurements with suppressed noises are derived based on a new adaptive mean filter originated by empirical mode decomposition (EMD). The experimental results demonstrate the proposed system can reduce the temperature substantially (almost 30% at the measuring point) and the results are highly consistent with those of numerical simulation. The proposed cooling system is a prospective enhancement for development of smart cutting tools.
