Comparison between Carbon Nanofiber (CNF) Nanofluid with Deionized Water on Tool Life and Surface Roughness in Turning of D2 Steel
Keywords:turning, nanofluids, tool life, flank wear, surface roughness
This paper presents the experimental study of the comparison between carbon nanofibers (CNF) nanofluid with deionized water in turning of D2 steel. The CNF nanofluid was prepared by mixing the nanofiller with surfactant using an ultrasonic homogenizer. CNC lathe machine and PVD coated carbide insert was used to perform the machining performance study with regards to a difference of cutting fluids. The cutting parameter was at the constant values for each cutting speed, feed rate and depth of cut. For machining performances evaluation, tool life and surface roughness are measured. From the results, it was found that by using CNF nanofluid, the tool life and surface finish were improved 25% and 22%, respectively compared to the one obtained with deionized water.
