Abstract: Conventionally, cutting fluids are applied in the form of flood to improve machining performance and tool life. However, the use of cutting fluid has detrimental effect in the form of environmental pollution and occupational health hazard. Researchers are trying to develop alternate methodologies to reduce or eliminate cutting fluids during machining. In this study, indigenously developed eco-friendly green cutting fluid (GCF) is used with minimum quantity cutting fluid (MQCF) technique during machining of hardened AISI H-13 steel. Cutting force, feed force and centre line average (CLA) surface roughness were measured at different cutting conditions. Performance of MQCF was compared with flood coolant using GCF and dry machining. The morphology of the rake face of the tool was examined with optical microscope and scanning electron microscope. Cutting force, feed force, coefficient of friction and CLA surface roughness was reduced with MQCF using GCF as compared to flood coolant and dry machining.
