Two of the important parameters in grinding operation are surface roughness of the workpiece and the amount of consumed energy. These parameters are strongly affected by the condition of grinding wheel surface which is dependent on the dressing parameters. Predicting the roughness of the grinding wheel surface after dressing with known dressing parameters can improve the grinding process. Researchers have presented several models of the grinding surface after dressing. In this article, these models are analyzed and an improved model along with computer simulation of grinding wheel surface is presented with regard to rotary dressing parameters. Finally, the model is verified with experimental results. The theoretical values reasonably compare with experimental results. On the basis of this model and experimental results the effect of different rotary roll dressing parameters on grinding wheel and workpiece surface roughness are discussed.
