  • Unit for continuously measuring shape defects of a part, and measuring process used in this unit.
    Patent number: 5276974
    Abstract: A unit for measuring shape defects of a part includes an installation plane (1), a presentation unit (2) receiving part to be measured, a measuring machine (10) mobile along three axes (X,Y,Z) and equipped with a sensor (17), and a computer (20). The sensor continuously follows the shape of the part, the variations recorded by the sensor determining a fourth axis (W). Shape deviations are displayed based upon the instantaneous acquisition of the four measuring displacements.
