Previous studies found that tool life and surface roughness in machining aluminium alloy 7075-T6 using cemented carbide are unfavourable compared to other materials. However, this observation needs further study. Thus, a raw block of aluminium alloy 7075-T6 was proposed in this experiment. An eight-run experiment was designed according to full factorial design based on two levels of cutting speed (500 m/min, 600 m/min), feed rate (0.12 mm/tooth, 0.15 mm/tooth), and axial depth of cut (1.40 mm, 1.70 mm) and then analysed employed ANOVA. Cutting tool life was restricted by tool wear in the milling process. The microscope and portable surface roughness tester were employed to analy...

MQL and dry cutting were eco-friendly approaches that highlight essential issues in the field of manufacturing technology. Thus, further investigation required to observe the intensity of those approaches. The experiment was done on computer numerical control (CNC) five axes milling machine at distinct machining parameters, which are cutting speed (500 and 600 m/min), feed rate (0.12 and 0.15 mm/tooth) and axial depth of cut (1.4 and 1.7 mm), while the radial depth of cut restricted to 7 mm. The effect of fluid approaches and machining parameters on eight samples have analyzed the result of the setting of three factors and two levels in accordance with the full factorial design and analyzed further using ANOVA. The MQL flow rate was set ...
