The method of the simulation developed by this study is based on replacing an actual grinding process to a computer program as faithfully as possible, where working model of effective grains, their cutting mechanism, effect of machine rigidity, etc. are taken into account. This paper describes the comparison of the simulated results with the experimental ones in various grinding modes, that is, cylindrical plunge grinding, cylindrical traverse grinding, surface grinding and internal grinding. A CBN wheel is employed in a cylindrical plunge grinding mode, and in other grinding modes an aluminum oxide grain and a green silicon carbide grain wheel are used. Performance of the simulation needs to model cutting edges of grains suitably which are determined by truing-dressing operation, a wheel composition, etc. In any grinding mode the simulated results agree well with the experimental ones. In order to obtain the useful results by the simulation, it is important to input the suitable parameters for the cutting edge wear, standard deviation of cutting edge distribution on wheel and specific grinding force of work material.
