摘要： An apparatus for checking the length (H) of a chamfer (7) delimited by a first surface (5) and by an edge (S), comprises two feelers (15, 25)—movably connected to a same supporting frame (20)—and respective transducers (16,26). The transducers supply signals (T1, T2) indicative of displacements of the respective feelers along mutually perpendicular directions (Y, X). A checking method includes moving the supporting frame at a constant speed so that, during the movement, one of the feelers scans the chamfer and the other cooperates with the first surface. The signals of the respective transducers are acquired and transmitted synchronously to a processing unit (40) which processes them together with information on the mutual position of the two feelers to obtain the length of the chamfer.

摘要： An apparatus for checking the diameter of crankpins (15) of a crankshaft in orbital motion about a geometrical axis in a numerical control machine tool includes a V-shaped reference device (10), a measuring device (6) and a support device (4) fixed to the tool holding slide (2) that movably supports the reference device and the measuring device. A control device (50) for controlling automatic displacements of the apparatus towards and away from a checking condition, includes a programmable electric motor (60) and a transmission mechanism (62). The programmable electric motor is programmed to define a start position in which the automatic displacement of the apparatus away from the checking condition can be stopped, for instance a rest position or an intermediate position between the rest position and the checking condition. The programmable electric motor is also programmed to define a displacement speed and a checking method includes steps for controlling the automatic displacements towards the checking condition.

摘要： Measuring assembly with a measuring apparatus and a recognition system, and recognition method to detect the correct positioning of a removable device such as a comparator to check the shape and/or dimensions of a mechanical part with respect to a stationary part that includes at least one mechanical reference for the removable device. The system comprises a field source disposed in the stationary part that generates a field and a matching element disposed on the removable device that is able to alter the propagation of this field if correctly positioned relative to the field source. A sensor fixed to the stationary part in an appropriate position detects or not the field and generates a resulting detection signal detection or non-detection signal. A processing unit receives the signal generated by the sensor and on the basis of this provides information about the correct or incorrect positioning of the removable device with respect to the stationary part. The recognition system can be of the magnetic or optical type.

摘要： A method for measuring the axial runout of a plane surface (22) of a workpiece (2) with respect to an axis of rotation (6) by means of a linear image sensor (19), in which a first optical scanning of the non-rotating workpiece is performed by translating the sensor relative to the workpiece along a direction (Z) parallel to the axis of rotation to obtain a first light intensity trend (I1) of a pixel (23) as the relative position between the workpiece and the sensor varies, and a relative position (ZR) of plane surface is determined as a function of the first light intensity trend. A second optical scanning of the workpiece is performed in the relative position of the plane surface while the workpiece rotates with respect to the axis for obtaining a second light intensity trend (I2) of the pixel as the angular position (θ) of the workpiece varies. A maximum position value and a minimum position value (Zmax, Zmin) are determined from the first light intensity trend using, as input data, light intensity values derived, or obtained by processing, by the second light intensity trend, and the axial runout is calculated as the difference between the maximum and minimum position values.

摘要： A system for checking size and/or position of an edge (5, R, T) of a workpiece (1, 1R, 1T) comprises two checking elements including matching elements (6, 7; 16, 17) which comprise respective surfaces having tapered matching zones (8, 9) adapted to cooperate with the edge (5, R, T) of the workpiece (1, 1R, 1T) along a longitudinal direction, and a transducer element (11) that provides electrical signals (M, M6, M7) indicative of the cooperation between the matching zones and the edge. The matching zones define slope angles (α, β) with respect to the longitudinal direction that are different from each other. A method that uses such a system for checking includes bringing the matching elements in a checking condition in which the respective matching zone cooperates with the edge to be checked, detecting the electrical signals provided by the transducer element, and processing such signals with reference signals indicative of the cooperation between each matching zone and a reference edge. System and method can be advantageously applied in checking the diameter of an edge of a valve seat (2).

摘要： Method and apparatus (1) for measuring a manufacturing deviation in an external gear (2). The gear is arranged onto a stationary central pin (3), the external diameter of which is smaller than the internal diameter of the gear so that a relative movement between the gear and the pin is allowed; a coupling member (5), preferably including a head (17) that does not rotate and is adapted to fit into the teeth of the gear, is urged with a predetermined strength against the teeth of the gear in order to mesh with the teeth and concurrently bring an internal lateral surface of the gear into engagement with an external lateral surface of the pin. The position of the central axis (A) of the gear is determined and the manufacturing deviation of the gear is determined as a function of said position. The deviation so determined can be corrected as a function of a reference distance (D) indicative of the radial dimensions of the gear.

摘要： Methods and apparatuses are used for optically measuring by interferometry the thickness (T) of an object (2) such as a slice of semiconductor material. Readings of the object thickness by optical interferometry are carried out, rough thickness values (RTW) are obtained and frequencies, indicating how often the rough thickness values occur, are evaluated. A limited set of adjacent rough thickness values whose frequency integration or summation represents an absolute maximum is identified, and the actual value of the thickness of the object is determined as a function of the rough thickness values belonging to said limited set of values. The rough thickness values can be divided up into classes (C) with corresponding frequencies (F), and in this case, a preponderant group (Gmax) of thickness classes is identified as the above-mentioned limited set of adjacent rough thickness. A lower reject threshold (Rmin) and a higher reject threshold (Rmax) that define a searching interval including the actual value of the object thickness are also determined, and all the rough thickness values that are outside the searching interval are eliminated from further processing. When measuring the object during a surface machining, the reject thresholds are progressively and automatically updated as a function of a gradual thickness reduction that the object undergoes.
