The paper submits a method to calculate thermal deformation and manufacture error in surface grinding. The author estab-lished a simplified temperature field model, and derived the thermal deformation of the ground workpiece. It is found that there existsnot only a upwarp thermal deformation, but also a parallel expansion thermal deformation. A upwarp thermal deformation causes aconcave shape error on the profile of the workpiece, and a parallel expansion thermal deformation causes a dimension error in height.The calculations of examples are given and compared with presented experiment data.
