Abstract

This paper presents an experimental study on the impact of coolant viscosity on the surface roughness of Inconel 600 material processed using a lathe. This research employs sequential experimental methods, encompassing a coolant viscosity test, specimen machining with a lathe, and surface roughness test. The standard for the roughness grade number is defined by ISO 1302. The study effectively demonstrates the use of a refractometer as a reliable and practical alternative for determining coolant quality in % Brix units, which strongly correlates with coolant viscosity. The research findings reveal that an increase in coolant viscosity results in a smoother surface roughness of the workpiece, while a decrease leads to an increase in surface roughness. Specifically, the average viscosity of 8%, 10%, and 13% Brix coolant results in an average surface roughness of Ra 11.83 μm, Ra 10.09 μm, and Ra 7.23 μm, respectively. The average roughness grade number based on this study is N9 - N10. However, the study also identifies the need for further mathematical calculations to establish a link between coolant concentration, % Brix, and coolant viscosity. This opens up an intriguing avenue for future research and holds the potential to significantly enhance our understanding of the relationship between these variables.
