MULTI-RESPONSE OPTIMISATION OF MACHINING PARAMETERS IN TURNING AISI 304L USING DIFFERENT OIL-BASED CUTTING FLUIDS
Keywords:Cutting fluids; Surface roughness; Temperature; Cutting tool.
Properties of melon seed and beniseed oils which are considered as “environmentally” friendly oils were investigated and the performance evaluation of the formulated beniseed and melon seed oil- based cutting fluids were carried out. American Iron and Steel Institute (AISI) 304L alloy steel was used as workpiece and tungsten carbide as cutting tool, while commercial mineral oil- based cutting fluid was used as a control experiment. The viscosities of the melon seed oil and beniseed oil- based cutting fluids were 1.53 mm2/s and 0.86mm2/s, while their pH values were 8.2 and 8.7 respectively. The optimal multi-response turning parameters was achieved using cutting speed of 159 rev/min (level 3), feed rate of 0.9 mm/rev (level 3), depth of cut of 1 mm (level 2) and type of cutting fluid of 1.53mm/s (level 3). The ANOVA results show that feed rate has the most significant effect on the surface roughness (92.93%) and cutting temperature (27.51%).
