Stiffness affects either a residual stock removal behavior and a self-excited chatter vibration, both of which are usually caused by the deflections of grinding wheel and work-support systems in ordinary grinding machine. Hence, the stiffness design method which makes the machine free from both behaviors with rational amount of static and dynamic stiffnesses is desired so far. The present paper proposes the way how much amount of static stiffness should be recommended in order to obtain proper spark-out time for a residual stock removal. This recommended static stiffness is then divided to the wheel and work-support systems in such a way as to obtain minimum damping ratios, but enough to avoid an occurrence of chatter vibration from each system. In the case when those damping ratios may become larger than the value which can be realized in ordinary cast iron or welded machine tool structures, the initial static stiffness is increased gradually until the damping ratio will reach to the settled reasonable value. This repetitive operation method is developed.
