  • Publication number: 20210316393
    Abstract: In a method for guiding a cutting head in relation to a material, a position and a speed of the cutting head are set by means of a drive unit depending on a desired position value and a desired speed value established by an interpolator unit, a control signal for the drive unit is determined, a distance between the cutting head and the material is determined with a distance sensor, and a corresponding distance signal is provided. The distance signal is compared with a predetermined comparison distance to yield a distance-control signal, and the control signal for the drive unit is additionally determined dependent upon a distance-control signal. The comparison distance is subtracted from the distance signal and the difference is superimposed on the actual position signal, which is delayed by a first time period, wherefrom the distance-control signal is determined.

  • Patent number: 10556341
    Abstract: The invention relates to a method (100) for determining an optimised trajectory for a non-productive movement of a tool (10) of a machine tool, from a starting position (12) to an end position (14). The non-productive movement is carried out in a spatially restricted travelling area (20) which is represented by geometric conditions. The method according to the invention is executed with the avoidance of collisions and comprises the step of determining a first trajectory (32) of the tool (10) by means of a travel-finding algorithm. In this step, the first trajectory (32) is optimised for the non-productive movement with respect to at least one selectable target parameter.

  • Patent number: 10491195
    Abstract: The invention relates to a method (100) for switching between desired value filters (26, 28) of a drive means (52) for a machine axis (10, 12) during operation. An input signal (20) is applied to the first and to the second desired value filter (26, 28) for producing a first and a second output signal (23, 33). Then any deviation between the first and the second output signal (23, 33) is determined. If the deviation falls below a threshold value, the first desired value filter (26) is separated from the drive means (52) and substantially simultaneously the second desired value filter (28) is connected to the drive means (52). The desired value filters (26, 28) have different running times (19).

  • Patent number: 9859870
    Abstract: A control facility for controlling a controlled system experiencing a disturbance includes a front nodal point receiving a target value and an actual value outputted by the controlled system and supplying a difference value corresponding to a difference between the target value and the actual value to a compensation circuit. The compensation circuit supplies a frequency-filtered and time-delayed signal formed as the sum of the weighted difference value and a weighted feedback signal as an input to a controller for the controlled system. The sum of a filter delay time and of first and second propagation delays is an integer multiple of the cycle duration of the disturbance, and a sum of the filter delay time and the first propagation delay is an integer multiple of the cycle duration minus a propagation time, which elapses until a change in the target value causes a change in the actual value.

    Abstract: A control facility for controlling a controlled system experiencing a disturbance includes a front nodal point receiving a target value and an actual value outputted by the controlled system and supplying a difference value corresponding to a difference between the target value and the actual value to a compensation circuit.

  • Publication number: 20140068947
    Abstract: A method for producing a bearing ring (20, 29), in particular a tapered roller bearing ring, including the following steps: making available an annular disc (8; 9), and forming the disc (8; 9) to provide a substantially cylindrical bearing ring and producing a raceway (19; 28) of the bearing ring in a single operation by extrusion. According to the invention, the method achieves the object of providing a simple method for producing bearing rings, in particular for tapered roller bearings, which delivers high unit numbers and in which it is possible to dispense with a finishing operation.

  • Patent number: 6982536
    Abstract: A device and method for apportioning a movement of a machine element driven by at least two drives for movement along a drive axis of a machine tool or production machine are described. A low-pass filter filters predetermined desired drive axis values to generate filtered desired drive axis values, with a first controller receiving the filtered desired drive axis values as control input value for controlling a first of the at least two drives. A delay unit with a constant group delay time temporally delays the desired drive axis values and generates delayed desired drive axis values, whereafter a subtracter determines a difference between the filtered desired drive axis values and the delayed desired drive axis values. A second controller receives the determined difference and provides, based on the determined difference, a second control input value for controlling a second of the at least two drives.
