    摘要： The invention relates to a punching and/or nibbling machine comprising a Z-axis drive for driving a tool, which can be moved in a vertical direction and which can be received by a tool receiving portion, for machining sheet-metal workpieces and comprising a CNC system for controlling the Z-axis drive, said CNC system providing an interface for a data channel to a higher-level control system or to another CNC system of an X/Y-axis drive for moving the sheet-metal workpieces relative to the tool in horizontal directions (X, Y). The tool receiving portion can be rotated about its vertical longitudinal axis (34) by a C drive, which is controlled by the other CNC system, during a vertical movement when machining sheet-metal workpieces. An angle sensor for detecting the angle information of the C drive is provided, and the CNC system is designed such that said system determines a Z target value as the reference variable of the Z-axis drive from the angle information. The invention also relates to a method for controlling such a punching and/or nibbling machine.

    摘要： The invention relates to a method for operating a hydraulic driving device (10) with a hydraulic cylinder-piston unit (12) having a working piston (16) which is movable along a working direction (14) between an upper dead centre and a lower dead centre, wherein a desired value for the position of the working piston along the working direction is predetermined, and an actual value of the position of the working piston along the working direction is detected, and the movement of the working piston is regulated depending upon the desired value and the actual value. The invention further relates to a hydraulic driving device (10).
