Abstract: A device has a displaceable device part, a drive, which is configured to drive the displaceable device part and to thus induce a movement in the displaceable device part, and a control unit, which is connected to the drive and is configured to control the drive. The device further has a first signal transmitter for determining a position and/or speed of the displaceable device part. The first signal transmitter and/or a first signal evaluation device, which is connected to the signal transmitter, are connected to the control unit such that the control unit receives information from the signal transmitter about the position and/or speed of the displaceable device part during operation of the device and controls the drive on the basis of the information received. A second signal transmitter of the device serves to monitor and/or redundantly determine the position and/or speed of the displaceable device part.

Abstract: A machine part, such as a laser, is moved along at least one axis of movement relative to a workpiece. Position pulses are generated by means of an incremental encoder, with the number of position pulses in a position pulse train being representative of the movement position of the machine part. A trigger signal for the machine part is generated when the current number of position pulses corresponds to a predefined number of pulses. In a preferred embodiment, the current number of position pulses and the defined number of pulses are compared remote from a higher-level drive control circuit.

Abstract: 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.

Abstract: The invention is directed to a method which is provided for controlling coordinate measuring apparatus wherein a probe head (2) is moved and has a movably attached probe unit (24) attached thereto. The probe unit (24) is charged with a measurement force Fmeas relative to the probe head (2). The measurement force Fmeas operates against the mass inertial forces Fzp which occur because of acceleration of the probe. The measurement force Fmeas is comprised of a desired measurement force Fdes and a corrective measurement force Fcorr. The desired measurement force Fdes is constant in magnitude and is directed perpendicularly to the surface of the workpiece (15) to be measured. The corrective measurement force Fcorr at least partially compensates for the mass inertial forces (Ftr, Fzp) which occur because of the acceleration of the probe unit (24).

The probe pin (19) is movably attached to the probe head (2). In the method, the probe pin for measuring the workpiece (15) can touch down on the surface of the workpiece to be measured or can be lifted off of this surface. The speed of measurement is increased by selecting the angle (.alpha.down, .alpha.up) between the direction of movement vres of the probe head (2) when touching down or when lifting off and the projection of the direction of movement toward the plane tangential to the workpiece surface in the touchdown/liftoff point (Pdown, Pup) to be less than 30.degree..
