    摘要: A machine part is guided along a defined movement path over a workpiece surface. The machine part is held at a defined distance from the workpiece surface during this movement. For that purpose, at least one distance sensor is provided that runs ahead of the machine part with a defined lead. A plurality of distance values indicative of a distance between the distance sensor and the workpiece surface are determined along the movement path. A plurality of control values are determined as a function of the distance values. The defined distance is repeatedly adjusted by means of the control values. In accordance with a first aspect, the distance values are determined at measurement points distributed with a first grid spacing along the movement path, while the control values are determined for actuating points distributed with a second grid spacing along the movement path, the first and the second grid spacings being different. According to a second aspect, the machine part has a linear range of activity on the workpiece surface, and the distance between the machine part and the workpiece surface is controlled by means of a distance control value and an angle control value, which are derived from distance values acquired from at least two distance sensors, which are laterally offset from one another.

    摘要: A machine part (12) is guided along a defined movement path (28) over a workpiece surface (23). The machine part (12) is held at a defined distance (50) from the workpiece surface (23) during this movement. For that purpose, a distance sensor (14) is provided that runs ahead of the machine part (12) with a defined lead (18). A plurality of distance values between the distance sensor (14) and the workpiece surface (23) are determined. A plurality of control values for adjusting the defined distance (50) are determined as a function of the distance values. The defined distance (50) is repeatedly adjusted by means of the control values. In accordance with one aspect of the invention, the distance values along the movement path (28) are determined by means of a first grid spacing (46). The control values are determined along the movement path (28) with a second grid spacing (44). The first and the second grid spacings (46, 44) are different.

    摘要: 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. It is particularly preferred if the current number of position pulses and the defined number of pulses are compared in a comparator which is arranged on an interface card of a computer unit, with the drive control circuit for controlling the movement of the machine part being implemented with a closed loop controller in the form of a controller program, which is cyclically executed by a central processor of the computer unit.

    摘要: A machine has a frame structure for moving a machine head in one or more spatial directions. The frame structure comprises an actuator and an air bearing for moving the head. The machine also comprises a compressed air feed connected to the air bearing for providing a compressed air flow. A restrictor defines the compressed air flow to the air bearing. The machine has a first operating state, in which a high compressed air flow is defined and in which the actuator can be actuated. The machine has a second operating state, in which a compressed air flow lower than the high compressed air flow is defined. In the second operating state, the actuator is secured against actuation from a closed-loop position controller, while the closed-loop position controller is maintained in operation.
