Title:
WORK MACHINE VIBRATION MONITORING METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/062445
Kind Code:
A1
Abstract:
This vibration monitoring method has a step for displaying the number of times a tool passing frequency (TPF) peak that is the peak acceleration at a tool passing frequency has exceeded a TPF threshold value in a display column 56a of a total threshold crossing display part 56, a step for displaying the number of times harmonic TPF peaks at harmonic frequencies have exceeded harmonic TPF threshold values in display columns 56b–56d of the total threshold crossing display part 56, and a step for displaying a comparison of the number of TPF threshold crossings and the number of harmonic TPF threshold crossings in a variation display part 58.
