Abstract
PURPOSE:To prevent a system error and to improve measurement accuracy even when a measurement point on the curved surface of a work is measured by moving the tip of the probe of a sensor and bringing it to contact with the measurement point of the work in a normal direction. CONSTITUTION:When the measurement point (a) on the curved surface 5a of the work 5 is measured, the tip of the probe 7f of the sensor 7 is positioned at a specific position (b) on a normal (l) passing the measurement point (a) of the work 5 which is supplied to an automatic machine tool 3 and positioned. Then a three-dimensional layout machine 6 is driven in an X-axial and a Y-axial direction in combination to move the tip of the probe 7f of said positioned sensor 7 and also is brought it to contact with the measurement point (a) of the work 5 in the normal direction. Consequently, an unshown sensor element in the sensor 7 detects the displacement quantity phi in the direction of the normal l from the drag at the measurement point (a). Then the position of the measurement point (a) is found from the displacement quantity phi and the vector in the direction of the normal l.
