| Abstract: | A great deal of experiments of cutting austenitic stainless steel 1Cr18Ni9Ti with TiCN coated and TiAlN coated novel special drills were conducted to study the influence of cutting speed and cutting feed on cutting deformation coefficient, and the relationship between the deformation coefficient and drilling force, torque and temperature. The results show that the cutting deformation coefficient represents the axial force strongly. The effects of cutting speed and feed speed on cutting deformation coefficient in drilling the austenitic stainless steel 1Cr18Ni9Ti were also obtained from the experiments. The research results would be of great benefit for the selection of proper tools and cutting parameters in drilling austenitic stainless steels. |
