Japanese Patent JP2020163546
Kind Code:
A
Abstract:
To provide a machine capable of suppressing an influence of sensor noise when specifying a value related to decentering of a grindstone.SOLUTION: A rotation command part 416 outputs a rotation command to a rotary motor. A rotation angle acquisition part 410 acquires a measured value of a rotation angle of a grindstone from a rotation angle sensor. A vibration acquisition part 411 acquires a value related to vibration in a cutting direction of the grindstone on the basis of a measured value of displacement by a displacement sensor. A decentration specification part 418 specifies a value related to a difference between a gravity center of the grindstone and a central axis on the basis of the measured value of the rotation angle and the value related to the vibration.SELECTED DRAWING: Figure 2
