Title:
METHOD FOR SUPPRESSING CHATTER OF OPERATING MACHINE
Document Type and Number:
WIPO Patent Application WO/2014/064953
Kind Code:
A1
Abstract:
A chatter suppression method for an operating machine detects vibration generated when rotation of a turning tool (22) or a work piece (W) starts, and when the vibration detected from the rotation start time is determined to exceed a vibration threshold value during idling of the machine main shaft, the vibration is analyzed using Fourier series expansion and the frequency due to regenerative chatter is calculated, and an estimated damping ratio is further added to the frequency due to the regenerative chatter to obtain a regenerative chatter avoidance frequency in order to adjust the speed of the main shaft (18).
