  • Patent number: 10503140
    Abstract: An oscillation permission/prohibition notification part of a control device notifies an oscillation command generation part of generation permission of the oscillation command when a position command value has not reached within a predetermined range of a machining end point of a workpiece, and notifies the oscillation command generation part of generation prohibition when the position command value has reached within the predetermined range. A control part includes a learning controller and a learning determination part. The learning determination part determines whether the oscillation command generation part has been notified of generation permission or generation prohibition of the oscillation command, turns learning control on when notification of generation permission of the oscillation command has been received, and sets the oscillation command to zero and turns off learning control when notification of generation prohibition of the oscillation command has been received.
