During forming of a workpiece 2 using profiled rolling tools 3, 4, a parameter of the workpiece, e.g. diameter or depth of profiling, is continuously sensed and is used to control the forming. Apparatus for carrying out out such a method comprises a sensing device (9) having a probe (11, 12) for sensing the workpiece (2) and feeding signals to a control system 18 connected to actuating means (20, 21) for controlling the forming operation. The roll force or speed of forming may be controlled by a feedback loop. <IMAGE> |
