Title:
METHOD AND DEVICE FOR SUPPRESSING CHATTERING OF WORK MACHINE
Document Type and Number:
WIPO Patent Application WO/2010/116825
Kind Code:
A1
Abstract:
Disclosed is a method for suppressing chattering of a work machine comprising a step (S1) of detecting vibration occurring when the rotation of a bit or a work (W) is started, a step (S3) of determining whether or not the vibration detected after the time when the rotation is started exceeds a threshold, a step (S4) of analyzing the vibration by Fourier series expansion when the vibration is determined to have exceeded the threshold, and a step (S21) of adjusting the rotational speed of the spindle.
