This paper presents a relationship between the surface finish, machining conditions and the noise level generated by the turning operation for machining of EN-19 alloy steel using PVD-TiN coated mixed ceramic (Al₂O₃+TiCN) inserts on a CNC turning centre under wet lubrication conditions. The machining parameters considered in this study include cutting velocity, feed rate and depth of cut. The levels of machining parameters for the experimental investigation are determined using full factorial experiment model and ANOVA is applied to find the effect of machining parameters on surface roughness. Additionally, noise generated during the cutting operation for all set of experiment trials is recorded to determines the relationship between machining conditions and the surface finish.

数控车削加工中，加工参数对采用PVD-TiN涂层混合陶瓷刀片加工EN-19钢的表面光洁度和噪声模式的影响

本文介绍了在CNC车削中心上使用PVD-TiN涂层混合陶瓷（Al ₂ O ₃ + TiCN）刀片对EN-19合金钢进行机加工时，表面光洁度，加工条件和车削过程中产生的噪声级之间的关系。在湿润滑条件下。本研究中考虑的加工参数包括切削速度，进给速度和切削深度。使用全因子实验模型确定用于实验研究的加工参数水平，并使用ANOVA来发现加工参数对表面粗糙度的影响。另外，记录在所有操作试验的切削操作过程中产生的噪音，以确定加工条件与表面光洁度之间的关系。
