This study evaluated the effects of cutting tool coating type and process parameters on flank wear and surface roughness in the turning of hardened 1.2343 hot work tool steel. Two different coated tungsten carbide cutting tools (CVD TiCN/Al₂O₃/TiN and PVD TiAlN/TiN), three different cutting speeds and three different feedrates were used for the experimental tests. Turning tests were designed based on the Taguchi method (L18). Experimental results demonstrated that the PVD TiAlN/TiN tool performed better under all cutting conditions. Analysis of variance results determined the feedrate, with an impact ratio of 82.61%, to be the parameter with the most impact on surface roughness, while flank wear was most affected by the cutting tool, with 89.12%.

本研究评估了切削刀具涂层类型和工艺参数对淬硬 1.2343 热作工具钢车削过程中后刀面磨损和表面粗糙度的影响。实验测试使用两种不同的涂层碳化钨刀具（CVD TiCN/Al ₂ O ₃ /TiN 和 PVD ​​TiAlN/TiN）、三种不同的切削速度和三种不同的进给率。基于田口方法 (L18) 设计车削试验。实验结果表明，PVD TiAlN/TiN 刀具在所有切削条件下都表现更好。方差分析结果确定进给率为 82.61%，是对表面粗糙度影响最大的参数，而后刀面磨损受刀具影响最大，为 89.12%。
