  • Patent number: 4594065
    Abstract: A control arrangement for moving tools brings these tools quickly into a desired position smoothly and without shock. The arrangement comprises means for preadjusting the required displacement so that the whole displacement path corresponding to the movement sweep of the tool is first determined. A calculation member (4) converts a given delay of the tool movement into a value corresponding to the speed of movement. An integrator (6) derives from the calculated speed value as a function of time a required position value. Upon movement of the tool the means for preadjusting the required displacement are continuously readjusted and the adjusted value for the drive (25) is determined by means of a comparison with the position value supplied by the actual displacement pick-up device (8).
