Abstract: A checking system (4) for checking dimensional and/or geometric features of a workpiece (W) comprises a support and locating element (30), a feeler (50) for touching the workpiece, an arm (42) supporting the feeler and movable with respect to the support and locating element, and a transducer device (14) to detect the position of a checking surface (41) of the arm with respect to the support and locating element and generate signals indicative of the features to be checked. At least one of the support and locating element and the arm is made of a material having density not higher than 1.6 g/cm3 and tensile strength not lower than 1.3 GPa. A procedure for manufacturing such checking system comprises the steps of obtaining a plurality of flat elements from a sheet of material having the aforementioned characteristics, and connecting the flat elements to obtain box-like structures that define at least one of the support and locating element and the arm. The apparatus can be advantageously applied for high speed checking shape or profile of rotating workpieces.

Abstract: Follower device (1) for measuring the profile of a workpiece (2), for instance a camshaft, with a measuring shaft (7) that is slidably coupled to a measuring body (6) so as to move along a measuring direction (D). The measuring shaft carries a feeler (3) that can rest on a surface of the workpiece, under the thrust of a thrust or resilient element (10). A position sensor (4) detects the position of the measuring shaft along the measuring direction, and an actuator (12) has a movable element (13) that moves between two end positions spaced apart from each other and cooperates with an abutment surface (31) of a mechanical portion integral with the measuring shaft in order to displace the measuring shaft. A contact sensor (14) cooperates with the actuator and with a mechanical portion that defines the abutment surface, for instance a positioning lug (11) rigidly linked to the measuring shaft, to detect whether the movable element of the actuator is in contact with the abutment surface.
