Abstract Nowadays, coatings have been widely deposited on cutting tool inserts due to their superior wear resistant and thermal barrier effect in metal manufacturing industry. Tool coatings avoid the direct contact between the workpiece and tool substrate, thus affecting the cutting temperature and machining performance compared with uncoated tools. This article aims to review the tool coating effects on cutting temperature during metal cutting process. Firstly, the factors influencing on cutting temperature with coated tools are analyzed including the geometric factors, thermal physical properties, coated tool-chip contact characteristics and coating-substrate diffusion layer. The determination approaches of these influencing factors are illustrated. Secondly, the predictive modelling for cutting temperature with coated tool including analytical thermal models and simulation methods (finite element method-FEM, finite difference method-FDM, boundary element method-BEM) are discussed, respectively. Thirdly, the experimental measurements on cutting temperature with coated tool are reviewed and analyzed. The possible perspectives of future work for investigating the tool coating effects on cutting temperature are proposed. This review would help to obtain knowledge of tool coating effects on cutting temperature with coated tools, thus for better selection and design suitable tool coatings by decreasing cutting temperature.

金属切削过程中刀具涂层对切削温度的影响：综合回顾和未来研究方向

摘要 如今，在金属制造行业中，涂层因其优异的耐磨性和热障效果而被广泛沉积在刀具刀片上。刀具涂层避免了工件与刀具基体的直接接触，因此与未涂层刀具相比，会影响切削温度和加工性能。本文旨在综述金属切削过程中刀具涂层对切削温度的影响。首先分析了影响涂层刀具切削温度的因素，包括几何因素、热物理性能、涂层刀具-切屑接触特性和涂层-基体扩散层。阐述了这些影响因素的确定方法。第二，分别讨论了涂层刀具切削温度的预测建模，包括解析热模型和仿真方法（有限元法-FEM、有限差分法-FDM、边界元法-BEM）。第三，回顾和分析了涂层刀具切削温度的实验测量。提出了研究刀具涂层对切削温度影响的未来工作的可能观点。该综述将有助于了解刀具涂层对涂层刀具切削温度的影响，从而通过降低切削温度更好地选择和设计合适的刀具涂层。回顾和分析了涂层刀具切削温度的实验测量结果。提出了研究刀具涂层对切削温度影响的未来工作的可能观点。该综述将有助于了解刀具涂层对涂层刀具切削温度的影响，从而通过降低切削温度更好地选择和设计合适的刀具涂层。回顾和分析了涂层刀具切削温度的实验测量结果。提出了研究刀具涂层对切削温度影响的未来工作的可能观点。该综述将有助于了解刀具涂层对涂层刀具切削温度的影响，从而通过降低切削温度更好地选择和设计合适的刀具涂层。
