    Abstract: A contact probe includes a stylus, a spring, a magnetic body, and a permanent magnet. The stylus is displaceable in an X direction and a tip of the stylus makes contact with a measured object. A first end of the spring is fixated and a second end provides spring force along the X direction. A position of the magnetic body is fixated with respect to the stylus. The permanent magnet is arranged separated from the magnetic body so as to generate a magnetic force along the X direction between the magnetic body and the permanent magnet.

    Abstract: Embodiments of the invention include a method for compensating a force at a probe element of a probing unit. The probing unit being attached to and moved along a defined moving path with a number of moving points by a coordinate measuring machine for approaching a measuring point at an object. The probing unit comprises an actuator which is arranged and designed in such manner that a force is applicable to the probe element with respect to at least one actuating direction in variable and defined manner, the force depending on an applied actuating signal. Movement information about an expected movement of the probing unit is received, the movement information provides information about an expected displacement behaviour of the probe element relative to the probing unit due to induced forces emerging by moving the probing unit.

    Abstract: A measuring device (10) and method for measuring a surface profile of a workpiece. A measuring carriage (15) is moved in a straight line at a distance from the workpiece surface in a moving direction (x), without accelerating a carried probe tip (25). The free probe end (40) of the probe tip (25) rests on the workpiece surface (11) with a measuring force (Fm) and is deflected during the measurement in a measuring direction (z), transverse to moving direction (x), the surface profile causes a track-dependent deflection (zT) of the probe end (49). A measured value receiver (45) detects the deflecting value (s) describing the deflection of the probe end (40) in measuring direction (z). In an analyzing unit (21), a measuring force change value describing the change of the measuring force (Fm) between the probe end (40) and the workpiece surface (11) is formed for detecting measuring errors/inaccuracies.

    Abstract: A micrometer, including a constant force drive spring actuator configuration, is disclosed which comprises a frame, an anvil, a spindle, a linear displacement sensor that senses a displacement of the spindle, and an actuator including a button which is configured to move the spindle toward or away from the anvil. The spindle drive is attached to a constant force spring actuator comprising at least one constant force spring coil extending toward the spindle and attached between the spindle and the frame such that the sum of their forces drives the spindle toward the anvil with an approximately constant force. In some embodiments, the constant force spring actuator comprises at least two parallel constant force spring coils, extending in parallel toward the spindle. The constant force spring may be made more compact, exert a greater force, and have an extended life relative to known configurations.
