The grinding process is dissimilar to other conventional machining methods such as turning and milling. The difference between them is due to not only the cutting edges of the grinding wheel don't have the uniformity but also the edges act differently on the workpiece at each grinding. In spite of many researches past decades, describing the grinding action between the grinding wheel and the workpiece was not made clearly. So statistical models and computer simulations that could overcome the variety of the cutting edges were introduced. These complexities and difficulties of illustrating the grinding process also raised an obstacle to the optimization of the grinding process and to the verification of the interrelationship between the grinding parameter and the obtained grinding result. In present paper, the response surface models to predict the grinding power and the surface roughness in the external cylindrical grinding of the hardened SCM440 material and also to help the selection of grinding conditions by using the contour plot of the response surface were developed.
