EXPERIMENTAL INVESTIGATION OF TOOL WEAR AND SURFACE ROUGHNESS BY THE INFLUENCE OF VARIOUS CUTTING FLUIDS IN TURNING OPERATION
Keywords:Surface Roughness, Cutting Fluid, Groundnut oil, Coconut Oil, Turning Process
The main objective of this work is to understand how the tool wear and surface roughness are influenced by various cutting fluids and machining parameters in turning EN8 SAE/AISI 1040 steel. Cutting fluids should be chosen by acidic nature test and viscosity test. It should have proper lubricity and act as a coolant. Vegetable oils like groundnut, coconut, and sunflower are considered to check their properties. Among these oils, groundnut and coconut oils were selected based on their properties. Experimental studies on the performances of both newly developed environmentally friendly vegetable-based cutting fluids (coconut oil and ground nut oil) and commercial cutting fluids in turning processes were reported. Performances of cutting fluids were compared with respect to surface roughness, cutting and feed forces and tool wear during longitudinal turning ofEN8 SAE/AISI 1040 steel. Experimental results were also compared with dry cutting conditions. Based on the results, the best-cutting fluid was selected.
