摘要:
In a method and a device for machining an elongate workpiece that is not rotationally symmetrical in the form of turbine blades, the workpiece is supported by a steady rest that has clamping elements for clamping the workpiece on the cross-section thereof that is not rotationally symmetrical. After clamping the workpiece, the steady rest moves with its open clamping elements along the longitudinal axis of the workpiece into a supporting position. During movement of the steady rest into the supporting position and/or while the supporting position of the steady rest is being changed, a collision between the open clamping elements of the steady rest and the workpiece is prevented by a program-controlled rotation of a rotary part of the steady rest.
摘要:
A method for interlinking regulation and/or control functions for a motor vehicle, the communication structure of the control or regulation functions is defined by way of graphs containing nodes and directed gridlines, the nodes of the graph representing control or regulation functions and its directed gridlines representing defined communication paths of the control or regulation functions.
