Title:
INDUSTRIAL MACHINE, ECCENTRICITY SPECIFYING DEVICE, ECCENTRICITY SPECIFYING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/203844
Kind Code:
A1
Abstract:
A rotation command unit outputs a rotation command to a rotary motor. A rotation angle acquisition unit acquires the measured value of a rotation angle of a grindstone from a rotation angle sensor. A vibration acquisition unit acquires a value related to vibration in the cutting direction of the grindstone on the basis of the value of displacement measured by a displacement sensor. An eccentricity specifying unit specifies a value related to the difference between the center of gravity of the grindstone and the central axis on the basis of the measured value of the rotation angle and the value related to vibration.
