摘要： A probe head having a probe head base and a stylus is provided for contacting a surface point on a workpiece. The stylus is moveable relative to the probe head base and has a defined rest position relative to the probe head base. For the contacting, the probe head is moved relative to the workpiece until the stylus touches the surface point with a defined contacting force. A correction data record representing a hysteresis behavior of the stylus with respect to the rest position is provided, and the contacting force is determined using the correction data record.

摘要： In order to determine spatial coordinates of a multiplicity of measurement points along a contour of a measurement object, a probe head is provided with a probe element that is movably supported on the probe head. During movement of the probe head along the contour, position measuring values of the probe head and deflections of the probe element relative to the probe head are determined. Spatial coordinates for the measurement points along the contour are determined from the position measuring values and deflections. The probe element is kept in contact with the contour during movement of the probe head by using an actuator to produce a defined contact force. The contact force is set as a function of a differential acceleration of the probe element relative to the probe head.
摘要翻译：为了确定沿着测量对象的轮廓的多个测量点的空间坐标，探针头设置有可移动地支撑在探头上的探针元件。在探针沿着轮廓移动期间，确定探针头的位置测量值和探针元件相对于探针头的偏转。沿着轮廓的测量点的空间坐标由位置测量值和偏转确定。探针元件通过使用致动器在探针头移动期间保持与轮廓接触以产生限定的接触力。接触力被设定为探头元件相对于探头的差速加速度的函数。
