Motorized spindles are one of the main sub-systems in a high-speed machine tool. In this paper, work is carried out to estimate the effect of machining operations on spindle deformation of a multi spindle automat. Spindle is supported on four bearings and analytical deflection calculation has been carried out considering the spindle as a continuous beam having 3 supports. Cutting forces acting on the spindle is calculated mathematically. Spindle deflection due to the cutting force has been calculated and validated using ANSYS. From the results, it’s clear that mathematical modeling deflection value is almost similar to ANSYS results. From the optimization of bearing span, results prove that change in bearing span doesn’t have much effect on spindle deflection.

Abstract


Motorized spindles are one of the main sub-systems in a high-speed machine tool. In this paper, work is carried out to estimate the effect of machining operations on spindle deformation of a multi spindle automat. Spindle is supported on four bearings and analytical deflection calculation has been carried out considering the spindle as a continuous beam having 3 supports. Cutting forces acting on the spindle is calculated mathematically. Spindle deflection due to the cutting force has been calculated and validated using ANSYS. From the results, it’s clear that mathematical modeling deflection value is almost similar to ANSYS results. From the optimization of bearing span, results prove that change in bearing span doesn’t have much effect on spindle deflection.
