On basis of chip formation mechanisms, tribology in cutting processes is described summarily in this review. Contacting pressure on a tool surface is extremely high and the contacting surface is fresh in the cutting processes. So, friction in the cutting is classified on a severe category in tribology field. Functions of cutting fluid are surveyed on shearing area, rake face friction area and flank friction area respectively, where cutting energy is converted into heat. Environmental measures of the cutting fluid are introduced and experimental results of a new technology are explained from the viewpoint of cooling ability. Finally, experimental tests, which can simulate the rake face friction, are introduced and effects of cutting temperature and surface roughness of the rake face on the lubrication ability are discussed on the basis of the experimental results.
