Estimation of Excitation Forces on a rotary tool

Abstract

Monitoring technology such as predictive maintenance and anomality detection during cutting process has been required. A wireless tool holder with acceleration sensors has been developed for monitoring tool vibration. For advancing functionally of the device, we have been proposed a method using inverse filters for estimating cutting force and torque from acceleration sensor signals during machining. In this study, excitation forces (x direction force, y direction force) on a tool mounted on the holder of machining center were estimated by the proposed method. Firstly, inverse filters were determined from single-input, single-output signals by excitation experiment on non-operating state. Secondly, the proposed method was examined by estimating an impulse signal.
