Abstract
MQL has been proven as the best method to replace flood machining condition due to its ecological and fluid coolant benefits. From the previous research, it is found that the benefits of MQL can be fully utilized by a proper applying and understanding the mist character. The supplied coolant comes with different flow patterns such as laminar, transient and turbulent flow. The different flow pattern produces different velocity of the moving particles and the knowledge of flow pattern are not highly stressed. This study is done to determine the appropriate flow pattern of the mist in order to choose the nozzle distance from the cutting tool for the minimum quantity lubricant using Particle Image Velocimetry (PIV). Particle Image Velocimetry (PIV) can be considered as a reliable tool to measure the mist flow to obtain mist velocity and flow pattern. The nozzle distance of 5 mm from cutting edge under MQL machining, shows reduction in temperature and cutting force using higher pressure to supply cutting fluid.
