Performance of Cold Coolant for Machining of Inconel 718 using Carbide Cutting Tool

Inconel 718 machining is challenging and difficult task in the aspect of good surface quality and minimum tool cost by machining process with low tool wear rate. In this contest, cold coolant machining tries to find the solutions by reducing the tool wear significantly in turning processes. The usage of the cutting fluids and its machining conditions are critically significant in order to completely utilized in the machining process. Usually, the maximum heat generation at chip-tool interface as critical cutting zone, and friction between the tool face and work surface is always the crucial factor on the surface quality. A good understanding of the methods to apply the cold cutting fluid at the cutting zone may significantly reduce the heat generation in machining and thus reduce the tool wear then the surface roughness also improved. Surface roughness and tool wear are always used as a quality indicator of machined job. In this research frizzed ice placed near to the coolant pump to convert the coolant in cold condition. During turning of Inconel 718 flooded cold coolant were drastically removed heat from the chip tool interface. As result, the cold coolant allows a tool life better than the conventional cutting fluid, moreover longevity of the cooling fluid also maintained.
