Article Preview

Combining the refrigeration and machining technology, the dry cold air at -35°C was gained. With the injecting feeding manner of the cold air for cutting, all application of the green technology is realized in turning manufacturing trials. In order to clarify the cooling and lubrication mechanism of cryogenic cold air, the cutting temperature, cutting forces, wear of cutting tool and cutting chip have been systematically researched with the help of numerical calculation and experiments. The cooling and lubrication effects, as well as the performance of machining quality improvement, enhanced by the low temperature air injecting, have also been analyzed in detail. The results arc as follows. Temperature measurements at several locations on the cutting tool insert agree with the simulation results. The performance of cooling-air spray jet with 25(Nm3/h ) on reducing the cutting tool temperature achieved a maximum effect
