Turbulent coolant inside cutting tool to control heat transfer during cutting process

Abstract

All cooling systems share one significant which is to reduce heat generated during cutting process. Many research attempts have been introduced to use internal coolant system fluid which coolant flow internally in the tool to remove heat generated during cutting processes. However, it raises another question of how to effectively control and optimize the internal coolant itself in the cutting tool. Therefore, one of the solution is applying the Computational Fluid Dynamic (CFD) technique in order to maximize the potential of internal coolant. The aim of this research is to analyze the turbulent parametric of internal coolant using ANSYS FLUENT. Furthermore, the static temperature and heat transfer coefficient also will be analyzed using different velocity of internal coolant. From the simulation result, the contours of static temperature for internal coolant cutting tool with velocity 5.0 m/s were showed the temperature of cutting tool is more cooler compare with velocity 4.2 m/s, 4.4 m/s, 4.6 m/s and 4.8 m/s. The values for heat transfer coefficient also showed the higher the velocity, the higher the value of heat transfer coefficient. The results also have been validated using analytical analysis and showed that there are not much different for the value of heat transfer coefficient for simulation and analytical. The findings of this research will give benefit to future machining process which is to reduce heat during cutting process in very efficient way. This research also will help another researcher in modelling, optimize and fabricate the internal coolant cutting tool for machining process which will reduce cost for coolant related and increase production profit.
