Title:
CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/066072
Kind Code:
A1
Abstract:
A control device 101 for controlling a drive unit 125 is provided with: a relative vibration-calculating unit 102 for calculating a component, which represents the extent of relative vibration occurring between the relative displacement of a tool with respect to a workpiece and a command position that is the target of a drive command, on the basis of a measured value measuring a physical quantity from which can be calculated at least one of the position, displacement, velocity and acceleration of the tool and/or a tool-holding unit on which the tool is fixed, a measured value measuring a physical quantity from which can be calculated at least one of the position, displacement, velocity and acceleration of the workpiece and/or a workpiece-holding unit on which the workpiece is fixed, and a drive command to the drive unit 125 for controlling the tool and/or the workpiece: and a relative vibration-suppressing unit 107 for outputting a command for suppressing relative vibrations on the basis of the calculation results of the relative vibration-calculating unit 102.
