Cutting fluids used in metal cutting are sources of pollution and health hazards. Therefore, eco-machining such as dry cutting, minimum quantity lubrication (MQL), cold air cutting and etc. have been proposed. The purpose of this study is to show the suitable cutting conditions of eco-machining. So, itis necessary to clarify the effects of cutting temperature and cutting method on tool wear mechanism. In this paper, the effects of cutting conditions (cutting speed and feed rate) and coolant (air, cold air, water, wet) on cutting temperature and tool wear form have been investigated. It is concluded from the results that cold air cutting will be effective in cutting conditions with the cutting temperature of 800 degrees or less. And there is cooling capability of the same grade as the evaporation of water on cold air cutting.
