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： In a machine tool (1) comprising a rotating spindle (2) and a vision system (7) for acquiring images of a tool (3) mounted on the spindle, for each value (VC) of an interval (ICN) of preselected rotational speed values centred on a nominal rotational speed value (VN) of the spindle, an image acquisition period (TA) is determined, that is a multiple of the rotational period (TR) of the spindle calculated for that preselected speed value and compatible with the vision system, and, while the spindle is rotating at the nominal rotational speed, a representative couple of tool images that are temporally spaced apart from one another of the image acquisition period is obtained, in order to obtain an estimated speed value (VS), associated to the nominal speed value, by selecting that preselected speed value to which the representative couple of images that are the most similar to each other on the basis of a similarity rule corresponds.
