    摘要: A process and device are provided for numerical control, in particular, of machine tools or robots having a plurality of axes. The process and device use base interpolations performed on a block-by-block basis and, in addition, one or more gear interpolations that convert a controlling guiding motion into a follower motion. Each gear interpolation is assigned parallel to one or more base interpolations and functions independently of block limits of a base interpolation in its own gear interpolation segments. The coupling characteristic of a gear interpolation ensues from a coupling factor, from a control curve stored in tabular form, or from a control curve stored as a mathematical functional equation. The gear interpolations can be obtained from so-called gear interpolation units and can be cascaded. Moreover, they can be fed back directly or indirectly and can be variably interconnected, as needed, with any existing sources and actuators. Besides generating geometric reference signals, gear interpolations can also be used for process control and process monitoring.

    摘要: The invention makes it possible to execute the pre-control and the fine interpolation in the drive (A) in the fast drive clock (tDR) with a slower path pre-setting in the clock (tNC) of the NC. For this purpose, in each NC clock (tNC) a setpoint speed value (nNC*) and the P gain (kP) of the NC position controller (L_NC) and the desired axle speed (nNC) and the average axle speed (nNCMW) during the last NC position controller clock are transferred from the NC to the drive. From this information, polynomial segments of the third degree are in each case generated on the drive side, valid for the duration of an NC position controller clock (tNC). They are constructed in such a way that the speed at the polynomial transitions is constant. A variable component of the position polynomial is determined as the fine position component xF, with which the setpoint position values are finely interpolated in the drive. Furthermore, the speed (nVor) and the torque (iVor) can also be pre-controlled in a finely interpolated form in the drive, since the polynomial of the third degree can be differentiated twice.

    摘要: In one aspect a device to simplify, and to reduce the costs of, the error-protected detection of the measured values in the control unit, without reducing the error protection of the system is provided. The device includes a pick-up device for detecting measuring signals. Independently operating evaluation devices are provided for the redundant determination of measured values from the measuring signals of the pick-up device. The data is transmitted to the control unit by means of error-protected transmission devices. A first evaluation device is used to determine a measured value, and a second evaluation device is used to determine a less precise, coarse comparison value. The device is also used to establish the accuracy of the measured value by comparing the value with the comparison value.
