Verification of Impulse mitigation theory for Suppressing spindle vibrations for Grinding quality Improvement

Abstract

Grinding quality evaluated by RZ is influenced by sub micrometer level spindle vibration. Spindle vibration is influenced by not only elasticity and viscosity of bearing, mass inertia and driving torque of rotating machinery but also the reaction force from the surface of the work via cutting edge. In this study, a hypothetical theory of dramatic invention for excellent grinding quality is proposed and comparative experiments to balancing technology is investigated.
