Abstract
Disclosed herein is a chatter suppressing method for a work machine. The method comprises the steps of detecting vibration occurring when a bar tool or a workpiece is started to rotate, determining whether the vibration detected from the start of rotation has exceeded a threshold, and analyzing the vibration by Fourier series expansion when it is determined that the vibration has exceeded the threshold and adjusting the number of rotations of the spindle.
