Abstract: In order to study the influences of coating on tool temperature distribution during cutting processes, a three-dimensional transient heat conduction analysis model of coated tools was established, the solving algorithm for three-dimensional temperature field of coated tools was developed based on thermal quadrupole methods and transient temperature distribution of  coated tools was obtained. The effects of coating thickness, thermal convection and thermal resistance at interface on the cutting temperature distribution of coated tools were studied, which provide theoretical bases for the determination of coating thickness, choice of cutting fluid and failure diagnosis of coated tools.

Key words: coated tool, three-dimensional transient analysis model, thermal quadrupole method, cutting temperature

摘要: 为研究涂层在切削过程中对刀具温度分布的影响,建立了涂层刀具的三维瞬态热传导分析模型,发展了基于热四极法的切削过程涂层刀具三维温度场求解算法,得到了涂层刀具的瞬态温度分布。研究了涂层厚度、热对流以及界面热阻对涂层刀具切削温度分布的影响,为切削加工中涂层厚度的确定、切削液的选择以及涂层刀具的失效诊断提供了理论依据。
