To analyze the influence law of swing grinding process parameters on surface residual stress, based on the thermal force sequential coupling theory,a finite element simulation model of cam residual stress based on temperature field was established,and the influence laws of process parameters such as swing frequency,swing amplitude,grinding wheel linear speed,grinding depth,workpiece speed,grinding wheel width and grinding wheel diameter on cam residual stress were studied.The results show that the residual stress increases with the increase of workpiece speed,grinding depth and grinding wheel linear speed;first increases with the increase of grinding wheel width,then tends to be flat;decreases with the increase of grinding wheel diameter;and slowly increases with the increase of swing frequency and swing amplitude.
