Abstract

The stiffness of the spindle is known to vary depending on the operating conditions. A convenient measurement method is necessary to evaluate the dynamic stiffness of various spindles. In this study, a small electromagnetic load generator was developed to measure the dynamic compliance of the spindle. In this paper, we report the results of measuring dynamic compliance by exciting the spindle of an actual vertical machining center using this generator.
