Investigating the machining parameters in turning of Monel K500 super alloy at dry and minimum quantity lubrication (MQL) by nano-fluids conditions

One of the new ways to improve the machining parameters in turning processes methods is the minimum quantity lubrication (MQL) method. In this study, the machining process of Monel K500 super alloy has been investigated using wiper type ceramic tool under dry and minimal lubrication with nano-fluid conditions. First, the necessary equipment was provided to perform the tests in dry and relatively dry (minimal lubrication) conditions. Then, the tests were completed in each of these conditions to determine the shear and feed rates. The utilized tool in experiments is the Wiper Ceramic Insert with the code CNGA 12 04 08 T01020WG-650 that is manufactured by Sandvik. The parameters of machining forces and surface roughness were measured during the tests. The results showed that the machining in the conditions of minimal quantity lubrication using nano-fluid not only reduced the amount of surface roughness, but also reduce shear force at low shear rates.
