IPC007: EVALUATION OF CUTTING FORCE IN MILING PROCESS OF ALUMINUM ALLOY 6061-T6 USING TUNGSTEN CARBIDE INSERTS WITH MQL METHOD UTILIZING HYBRID NANOFLUID

As an alternative to conventional metal working fluid in the end milling process, a combination of newly developed tri-hybrid SiO2-Al2O3-ZrO2 in aqueous-based nanofluid was delivered in the cutting zone using the MQL technique. The fluid has excellent thermal-rheology properties that can offer effective cooling and lubricating during the process. Besides, the application of tri-hybrid nanofluid is environmentally safe thus promoting sustainability manufacturing compared to the conventional working fluid. Cutting forces were investigated comprehensively throughout the study. Tri-hybrid nanofluid presents in atomizing conditions using minimum quantity lubricant (MQL) technique at the cutting zone. Industrial standard inserts namely uncoated, CVD TiCN-Al2O3 and PVD TiAlTaN tungsten carbide used in the experiments. End milling process variables were cutting speed, feed rate, depth of cut, MQL flow rate and nanofluid concentrations. The response data were analyzed statistically based on the design of experiment and regression models were developed for each response according to response surface methodology. Cutting force increased when the material is being removed at a higher removal rate with rapid feeding of the cutting process. During the cutting process of Aluminum Alloy 6061-T6, the cutting force, Fr measured was
