Cooling by air, water and mist in end milling is estimated by analyzing cutting temperature during end milling processes. Heat transfer by natural convection of air and water, forced convection of air and water, nucleate boiling and droplet evaporation are assumed on the surfaces of an end mill according to the cooling methods used. The effects of cutting speed, feed rate and coolant (air) velocity on the temperature are also investigated. The temperature change according to cooling methods is acceptable. This proves that the models of cooling are appropriately applied to the analysis.
