Abstract: A cold-solid deformation press with which there is detecting of a force occurring between two oppositely movable machine parts for monitoring especially of cyclically repetitive production processes, for example by deformation or machining. Desired values determined and stored in a preliminary run are continuously compared with actual values during the production. In order to improve the information-giving capability of such a process monitoring, and to protect the force-measuring elements against over-loading with simultaneous miniaturizing thereof, at least one significant component of force is detected in the form of stresses in at least one of the machine parts as the desired and actual values of the force which is to be monitored.

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.
