ABSTRACT:
A method is disclosed of detecting and recognizing deviations from normal cause of cyclically recurring processes for the shaping of workpieces, in particular upon the profiling of elongated blanks of circular cross section by shaping from the solid, for instance upon the hobbing or rolling of threads. In order to determine impermissible deviations already during the course of the process and be able to intervene in the process before the production of the next workpiece, the power expended to carry out a shaping process on the basis of a normal course of the shaping is determined from the start to the end of the course of the force output at a suitable point of a tool, and these values are stored and the corresponding values of each of the cyclically recurring shaping processes are determined and compared with the values stored, deviating values which exceed a predetermined range of tolerance leading to a sorting-out of the workpiece and/or to an interruption of the shaping processes, depending on the nature of the deviation.
