Notes:
Water vapor is a good, pollution-free and economical coolants and lubricants in greenmachining. In order to research the cutting temperature distributions with water vapor as coolantsand lubricants in machining, the experiments conducted under the conditions of water vapor ascoolants and lubricants and dry cutting. The cutting temperatures are studied by metal cuttingtheory, and then by employing the finite element method (FEM), the temperature distribution ofcutting region is simulated with application of water vapor as coolants and lubricants and drycutting conditions. The results show that the water vapor jet flow has high force-convection heattransfer coefficient and directly cooling action to reduce cutting temperature, and the stress, thelength of tool-chip interface are reduced with application of water vapor lubrication. So that thecutting thermal is decreased and water vapor has indirect cooling action. Under the conditions ofindirect and direct cooling action, the cutting temperature is reduced obviously with application ofwater vapor as coolants and lubricants
