عنوان انگلیسی Influences of Al2O3 Nanofluid MQL Technological Parameters on Thrust Cutting Force in Hard Turning Using CBN Inserts
چکیده انگلیسی مقاله High cutting forces generated from contact faces in hard turning process are still the huge challenge, which limits the productivity, lowers machined surface quality, and shortens tool life. Among them, the thrust cutting force strongly affects the hard cutting efficiency. This study aims to analyze the thrust force in turning process of hardened 90CrSi steel under Al2O3 Nanofluid Minimum Quantity Lubrication (NF MQL) technology using uncoated cubic boron nitride (CBN) inserts. Regression analysis was made to establish the dependence of the thrust force on NF MQL parameters. The results indicate that air pressure has the most significant influence on the thrust forces. The interactions between nanoparticle concentration and air flow rate (NC*Q) and between air pressure and air flow rate (p*Q) also showed the significant effects. The minimal value of thrust cutting force (Fy) could be achieved at Al2O3 nanoparticle concentration of 0.8%, air pressure of 4 bar, and air flow rate of 250 l/min. Moreover, the analysis results could be used to determine the reasonable set of NF MQL parameters for smaller Fy values in hard turning process.
