Abstract: The development of lubricants like, cutting fluids was traditionally based on mineral oil as a base Fluid. This fact is related to the technical properties and the reasonable price of mineral oils. Cutting fluids are used widely to reduce the negative effects of the heat and friction on both tool and workpiece. The cutting fluids generally produces three positive effects in the process such as heat removal, lubrication on the chip–tool interface and chip removal. Issues of using fluids in machining related to environment, health, and manufacturing cost that need to be solved and options to reduce their use has to be accomplished. Hence there arises the need for an ecologically benign metal working fluid in machining operations. A comparative study of Dry Machining and Wet Machining where rice bran oil and coolant oil (Shell Tellus-40) is used as the cutting fluid serves as the scope of this study. The results obtained with conventional flood cooling method are compared with that of Dry cutting. The experiment is carried out in a CNC lathe for turning operation on plain carbon steels EN8 and EN9 for surface roughness and tool life by varying parameter like Cutting speed and Feed keeping depth of cut constant.
Keywords: cutting fluids, CNC lathe technical properties and the reasonable price of mineral oils.
