Two of the Important parameters in grinding operation are roughness of the part and the amount of consumed energy. These parameters are strongly affected by condition of grinding wheel surface which is affected by dressing parameters. Predicting the roughness of grinding wheel surface after dressing with known dressing parameters, can improve the grinding process. Researchers have presented several models of grinding surface before dressing. In this article these models are analyzed and an improved model along with computer simulation of grinding wheel surface, with regard to disc dressing parameters, is presented and finally this model is verified with experimental results that were published before.
