Abstract (en)
[origin: EP0259508A1] The invention relates both to a method and a device for rolling workpieces of ductile material in which a rolling tool (2) is fed to the workpiece (1) and applies a rolling force to this. It is proposed in this context that, from a predetermined point in the working cycle, at least one specific distance (A) or a change in distance ( DELTA A) between workpiece and tool be detected and analysed for open-loop or closed-loop control of the subsequent machining process. For this purpose the necessary device should have at least elements of a path measuring system (6) in order to detect the relative positions of workpiece and tool. <IMAGE>
