There is less precedent that using ultrasonic processing emulsion to improve its cooling and lubricant capability at home and abroad, but using ultrasonic processing emulsion can improve its cooling and lubricant capability, decrease its dosage, up to aim at saving energy and decreasing letting, the study has newly proposed and developed a standard green cutting technology, hence researching results of theory significance and application value have been drawn.Firstly, the ultrasonic processing emulsion system was developed based on the emulsification of diesel oil, which provided postulate for investigation of cutting experiment that use the processed emulsion as cutting fluids.Second, comparing with dry cutting wet cutting, the cutting experiments using YT15 cutting 45 steel, with processed emulsion as cutting fluids was taken to study its action effect, and the single factor experiment was also taken to study the influence law of each factor to the cutting force, the deformation coefficient, the chip ship, the machined surface, which factors were treatment time,flux,concentration, water quality.Thirdly, with orthogonal experiment, the parameters: treatment time,flux,concentration, water quality, was optimized. The influence order of each factor on the main cutting force was analyzed, and the best combination was found.Lastly, the mechanism of processed emulsion as cutting fluids was taken as important problem to study using capillary model and physical chemistry.Result was that, on some condition, comparing with wet cutting, the main cutting force and the deformation coefficient were reduced about10%, better machined surface topography and regular long spiral chips. The molecule after treatment was smaller, small molecule appeared. The molecule after treatment entered capillary more easier than before, which could improve it’s osmosis; strong oxidant H2O2 also appeared, forming oxidation film was also easier; with these two aspects, ultrasonic processing could improve cooling and lubricant capability of emulsion.Using ultrasonic processing emulsion can improve its cooling and lubricant capability, can reduce its amount, decrease the harm to environment, be up to the object of energy-saving and emission mitigation.
