摘要
Abstract
GH4169 superalloy is a kind of hard-to-machine material and is widely applied in the aerospace and energy fields be-cause of its remarkable high-temperature resistance and corrosion resistance.The cutting process of GH4169 superalloy under dif-ferent cutting feed rates was studied.The cutting temperature was analyzed by means of simulation,and the wear behavior of coa-ted tools,along with the surface roughness,hardness and residual stress of the material,were discussed in conjunction with cutting experiments.The results indicate that with the increase of the feed rate,the cutting temperature rises gradually,the tool wear ag-gravates,and the surface roughness exhibits an upward trend.Meanwhile,both the residual compressive stress and hardness of the machined surface present a tendency of increasing initially and then decreasing.When the feed rate was 0.10 mm/r,the maximal residual compressive stress value amounted to 269.33 MPa,and the hardness attained the maximum of 292.64HV.In conclusion,when the feed rate surpasses 0.10 mm/r,the elevated cutting temperature is likely to result in intensified tool wear as well as the deterioration of the surface integrity of the machined workpiece.关键词
