EXPERIMENTAL INVESTIGATION OF DRILLING PROCESS USING NANOFLUID AS COOLANT
Abstract
Nanofluid coolant is one of the new formulation of cutting fluids used in machining in order to obtain better surface finish of products. In this study, the effect of various coolants (nanofluid and pure deionized water) and cutting parameters (cutting speed and feed rate) to the machining performances of titanium alloy was investigated by using drilling process. A series of experiments were conducted using Design of Experiment (DOE) and the machining performances were measured in terms of surface roughness and cutting temperature. The results show that better surface finish and lower cutting temperature can be obtained by using carbon nanofiber nanofluid compared to that of pure deionized water. The significant factors that influence the surface roughness of titanium alloy are feed rate and coolant. Coolant also plays an important role to reduce the cutting temperature during the drilling process.
