Abstract
Performance of tool life for coated carbide tool during turning Inconel 718 in dry condition was studied in order to increase the efficiency in turning process and reduce the machining cost. Coated carbide tool with thin layer of PVD TiAlN, CNMG 120408-QM 1105 was used to turn Inconel 718 with hardness 20.25 HRC. Taguchi method with the orthogonal array L9 was use in this experiment with the parameter v=60, 70, 80m/min, f=0.2,0.25,0.3mm/rev and d=0.3, 0.4, 0.5mm. Signal-to-noise ratio and analysis of variance (ANOVA) were employed to study the performance of tool life. According to results, cutting speed was significantly influence to the tool life, followed by feed rate and depth of cut. Increment in speed and feed rate will increase flank wear and shorten the tool life. v=60m/min, f=0.2mm/rev and d=0.3mm is the optimum parameter for tool life. It was discovered that flank wear rate gradually increase in the initial machining and accelerate significantly after flank wear width reach 0.1mm. Flank wear, crater wear, notch wear and nose wear are the wear occurs on the carbide tool during turning Inconel 718. Through the SEM, abrasion, attrition and adhesion are the wear mechanisms which can be seen on the cutting tool.
