据观察，为了在高温合金 Inconel 718 的加工中获得更好的性能，人们对使用 cBN 和/或陶瓷刀具给予了相当多的关注。然而，它们的成本限制了其在工程应用中的使用。本文研究了多层 TiN/TiAlN (PVD) 涂层和 TiN/Al2O3/TiCN (CVD) 涂层碳化钨刀具在高速车削 (HST) 高温合金 Inconel 718 时的性能。记录、分析和报告了涂层材料对切削力、切削温度、振动和声发射的影响。实验结果发现，TiN/Al2O3/TiCN (CVD) 涂层刀具在切削力和切削温度等切削加工参数方面优于 TiN/TiAlN (PVD) 涂层刀具。从振动信号的快速傅里叶变换 (FFT) 分析可以看出，CVD 涂层工具的振动比 PVD 涂层工具的振动要小。
It has been observed that considerable attention has been given to the use of cBN and/or ceramic tools for achieving better performance in the machining of superalloy Inconel 718. However, their cost limits the use in the engineering applications. In this article, the performance of multicoated TiN/TiAlN (PVD) coated and TiN/Al2O3/TiCN (CVD) coated tungsten carbide tools were investigated while high speed turning (HST) of superalloy Inconel 718. The effect of coating materials on cutting force, cutting temperature, vibration, and acoustic emission were recorded, analyzed, and reported. From the experimental results it has been found that TiN/Al2O3/TiCN (CVD) coated tool outperformed the TiN/TiAlN (PVD) coated tool in terms of machinability parameters such as cutting force and cutting temperature. From the fast Fourier transform (FFT) analysis of the vibration signals it was observed that the vibrations were less in case of the CVD coated tool than in case of the PVD coated tool.
