Abstract
Spindle stiffness is the ability of spindle to resist deformations under the influence of cutting forces. The magnitude of deflections at the spindle nose, where cutting forces from the tool are transmitted, decides the machining accuracy of the machine tool. In this paper, a method to evaluate the static stiffness of the spindle with a bearing system subjected to cutting force is presented. The static stiffness of the spindle is calculated analytically by evaluating the radial stiffness of the bearings and the deflection at the front end of the spindle. Finite Element Analysis is carried out on the spindle bearing system, and results are compared with analytical results. Further, experiments are carried out to validate the analytical and numerical results.
