Abstract

A jog-feed operation is set to enable rotation and movement of a coordinate system. During the jog-feed of the coordinate system, a robot is moved equivalently to the jog-feed steps. A tool distal end point of the robot is initially moved to the origin of a user coordinate system serving as a moving target. A jog-feed mode is set to a coordinate system jog-feed mode in conformity to the coordinate system itself. A translating jog-feed operation is carried out until the tool distal end point of the robot reaches a vertex of a workpiece. The tool distal end point of the robot is subsequently moved to a point on an axis of the coordinate system. A rotational jog-feed operation is carried out until the tool distal end point of the robot reaches an edge line of the workpiece. According to the above jog-feed operation, a robot control device calculates an amount of movement of the coordinate system.
