A Comparative Study of CNC Milling of Aluminium using Flood Coolant and Air Cooled Machining
The present work compares the performance of CNC milling operations using flood coolant and air-cooled machining of aluminium. At high speed and feed, the burr formation in air-cooled machining is significantly lower than that in flood coolant machining at the cost of surface roughness. SEM studies reveal higher oxidation of the workpiece in air-cooled machining. No significant difference in the hardness of the workpiece is observed.
