IntroductionIn chip forming processes,the two main func-tions for cutting fluids are cooling and lubrication.Cooling of the tool can produce significant tool lifeimprovements and keep the tolerances within suit-able limits[1] .The penetrating strength of micro-scopic lubricating film on the tool reduces the fric-tion contactlength and the apparentfriction- coeffi-cient leads to the decrease of chip compression,builds up edge formation,surface roughness,cut-ting forces and power consumption.Add… 相似文献
