Abstract:
A process for automatic control of a straightening process for a material to be straightened, including sheet metal, strips, sections, pipes and wire objects, in one of a straightening apparatus and a levelling machine having at least one straightening roller, adjustable with an actuator, the process comprising: predetermining, on a basis of which a process simulation model of a straightening process is to be performed and a process simulation program directly online settings of the at least one straightening roller, wherein during the actual performance of the straightening process recording changes of product data, including material properties, having an effect on at least one of an operation of the straightening process and dimensions of respective ones of the objects to be straightened, at least one actuator emitting a signal corresponding to resultant data and using the resultant data to calculate a setting of the at least one adjustable straightening roller, and a yield point of the material to be straightened being continuously determined as a function of a respective product the process data.
