The power utilization capacity of machine tool spindles depends mainly on stiffness at tool point. It is known in machine tools for instance in machining centers the spindle system could alone account for about 30 to 40% of stiffness at cutting point between tool and work piece. Even though there are 2 or more bearings as a pack at each front or rear location even then an approximate or equivalent stiffness is given at front and rear locations. This is because it is not possible to compute shaft deformations supported on more than 2 supports on a shaft it is not represented further each bearing has a number of rolling elements like ball or roller around 15 to 20.It is possible to predict the stiffness of a bearing by computing hertizian contact stresses at each rolling element going through nonlinear procedure In view of above it is necessary to develop a simplified methodology for modeling spindle system with bearings in a machine tool spindles. The methodology should facilitate 3D modeling the bearing in a large machine tool mesh at the same time the methodology should ensure precise results.
