Grinding-introduced residual stress is one of the key indicators of surface integrity. The modeling of macroscopic grinding process is reasonly complicated due to combined actions of multi-grains. A modeling method of stress field of macroscopic creep feed grinding process was proposed to predict the residual stress. When there is no phase transformation in grinding, a stress equivalence hypothesis was proposed to map the stress field between micro abrasive grain and macro grinding process. When there is phase transformation in grinding, a transformation-stress coupled model was established to describe the stress field. Both the two models were fully validated by the measured value of the residual stress distribution.
