Theoretical verification of Rotary resistance Impulse mitigation for Suppressing vibrations

Abstract

Rotary resistance as reaction force from the surface of the work via cutting edge which is rotated with grinder spindle causes spindle eccentric rotation where rotation center is distant from the rotational moment minimum center. In this study, the dynamics of spindle vibration by impulse reaction force caused by rotary resistance is investigated by a general vibration theory and the mechanism of how impulse force is mitigated by mass inertia force of a free slide weigh in a flange connected to spindle.
