ABSTRACT:
Axes used for posture alignment are selected from the axes of a work coordinate system W and a tool coordinate system T, and an angle of intersection between those selected axes are set. A robot is then driven so that the selected axes intersect with each other by the set angle of intersection in response to a posture alignment instruction, causing the tool to assume a target posture with respect to a workpiece. Further, angles for rotating the work coordinate system about each axis thereof are set, then the robot is automatically moved so that a coordinate system produced by rotating the work coordinate system by the set angle in response to a posture alignment instruction. Further, the tool coordinate system set at a movable part of a tool is automatically reset according to an amount of movement every time the movable part of the tool move, and the robot is manually fed based on the tool coordinate system thus reset.
