Abstract: In order to achieve the uniform removal of grinding materials on the surfaces of screw rotor， a new type of abrasive belt grinding device was developed， which was composed of contact wheel type and free type abrasive belt grinding tools. According to the contact characteristics of grinding tool and workpiece， the contact model was established by semi analytical method and geometric approximation method respectively， and the contact stress distribution laws in the contact areas were obtained. The material removal rate prediction model was proposed based on the ThunderGBM algorithm， the contact stress and grinding process parameters were used as inputs to predict the material removal rate of the screw rotors in belt grinding. The grinding experiment was designed and implemented for the five head screw rotor. The comparisons between experimental data and numerical results show that the proposed model has high accuracy and effectiveness.
