Claim 16:
17. A method for detecting a position on an edge of a workpiece, the method comprising:
obtaining a first determination result indicating whether the workpiece has been detected at a first detection position with the workpiece held at a machine tool;
obtaining a second determination result that indicates whether the workpiece has been detected at a second detection position different from the first detection position, the second determination result being different from the first determination result;
obtaining a third detection position that is between the first detection position and the second detection position;
obtaining a third determination result indicating whether the workpiece has been detected at the third detection position;
replacing the first detection position with the third detection position to provide a first replaced detection position when the third determination result and the first determination result are same, or the second detection position with the third detection position to provide a second replaced detection position when the third determination result is different from the first determination result; and
detecting, as the position on the edge of the workpiece relative to the machine tool, one position located between the first replaced detection position and the second detection position or located between the first detection position and the second replaced detection position.
