摘　　要：双端面磨削加工中,工件上下表面由两个端面砂轮分别以面接触形式磨削,具有较高的加工效率,但往往存在着表面材料去除量不均匀现象.为了分析双端面磨削中工件表面材料非均匀性去除影响因素,建立端面磨削中材料去除量分布模型,在不同磨削参数下进行仿真与实验研究.结果表明,砂轮与工件转速比的大小对工件表面去除均匀性具有显著影响.仿真与实验结果趋势一致,为改善端面磨削表面材料去除均匀性、提高表面质量提供了理论依据.In the double side grinding process,the two surfaces of the workpiece were ground separately by two end grinding wheels,which has a high processing efficiency.However,the removal non-uniformity of surface materials still exists.Material removal distribution model was established and the simulation and experimental researches were carried out under different grinding parameters in order to analyze the factors affecting the removal non-uniformity of surface materials in the double side grinding.The research demonstrated that the speed ratio of the grinding wheel and the workpiece has a significant effect on the removal uniformity of surface materials.The simulation data was consistent with the experimental results,which provides a theoretical basis for improving the removal uniformity of surface materials and surface quality.
