Abstract. Process controls are getting increasingly more common in forming. Nevertheless, they are not suitable to achieve consistent quality when dealing with varying process disturbances. Differing properties of the raw material and other external influences like temperature variations and vibrations make it hard to achieve the tightly specified tolerances needed in today’s production environment. Product property controls represent a solution for these difficulties and create the opportunity to integrate additional functionality into the product and the process. In this project, the implementation of a multivariable product property control is investigated using the example of a recently developed process, called punch-hole-rolling. It is targeted to control product properties such as the collar height and the hardness on the inner surface. It has been shown in previous publications that it is possible to control the collar height in 1.0338 by carefully choosing suitable process parameters. In recent works the possibility was presented to control the hardness by changing the same parameters, using the TRIP steel 1.4301. The publication at hand aims at proving the feasibility of the multivariable product property control by reviewing the previous results for 1.4301 and proving that it is possible to control the collar height and the hardness on the inside of the collar simultaneously. Further, a concept is presented for the implementation of such a control.
