ABSTRACT:
An apparatus for checking the geometrical features of mechanical pieces, including a feeler adapted to contact the macrogeometric profile of the piece to be checked, a transducer coupled to the feeler for providing a reference signal and a non-contacting sensing device including a reactive type transducer for providing a signal responsive to the microgeometry of the piece. A parameter indicative of the roughness of the piece may be obtained by processing the signals provided by the transducer coupler to the feeler and by the other transducer.
