ABSTRACT In the present research, an attempt was made to determine the suitable coated tool for drilling AA5052 nano hybrid sandwich sheet using Response Surface Methodology (RSM) and Taguchi method. The work aims at minimizing thrust force and torque on a friction drilling tool for drilling holes. Plasma Nitriding, Liquid Nitriding, and PVD Titanium Nitride (TiN) coating are applied on H13 steel tool material. Results indicate that for achieving minimum torque and thrust force, feed of 50 mm/rev and spindle speed of 4000 rpm to be used during drilling. Whereas, to reduce the drilling time, feed has to be increased up to 200 mm/rev. The maximum bushing height is 5.6 mm for Liquid Nitrided tool at 2500 rpm, 50 mm/rev, and 5.4 mm for PVD TiN-coated tool at 3000 rpm, 200 mm/rev, whereas 4.71 mm is the minimum bushing height for Plasma Nitrided tool at 3500 rpm, 150 mm/rev. The result obtained from RSM was compared with Minitab response optimizer and Harmonic Search Algorithm. PVD TiN coated tool exhibited the best performance in terms of low thrust force value of 84.70 N at 4000 rpm, 50 mm/rev and low torque value of 1.5395 N-m at 2500 rpm, 50 mm/rev.

FML复合材料涂层摩擦钻具的优化

摘要 在本研究中，尝试使用响应面方法 (RSM) 和田口方法确定适合钻孔 AA5052 纳米混合夹层板的涂层工具。这项工作旨在最大限度地减少摩擦钻孔工具上用于钻孔的推力和扭矩。等离子氮化、液体氮化和 PVD ​​氮化钛 (TiN) 涂层应用于 H13 钢工具材料。结果表明，为了获得最小的扭矩和推力，在钻孔过程中要使用 50 mm/rev 的进给和 4000 rpm 的主轴转速。然而，为了减少钻孔时间，进给必须增加到 200 毫米/转。液态氮化工具在 2500 rpm、50 mm/rev 时的最大衬套高度为 5.6 mm，而 PVD ​​TiN 涂层工具在 3000 rpm、200 mm/rev 时的最大衬套高度为 5.4 mm，而 4. 71 mm 是等离子氮化工具在 3500 rpm、150 mm/rev 时的最小衬套高度。从 RSM 获得的结果与 Minitab 响应优化器和谐波搜索算法进行了比较。PVD TiN 涂层刀具在 4000 rpm、50 mm/rev 时的 84.70 N 低推力值和 2500 rpm、50 mm/rev 时的 1.5395 Nm 低扭矩值方面表现出最佳性能。
