ABSTRACT
The mill process designer and/or analyzer needs to shorten the time between the idea and the practical application, to minimize costs. For this purpose, they designed pilot rolling facilities and simulated real rod and bar rolling processes. In a plate rolling experiment, this is relatively easy, because neither roll grooves nor guides have to be designed, and only the roll gap (pass height) change is enough to encounter the variation of specimen size change. However, performing the rod and bar rolling test is difficult, since we have to design roll grooves and guides, and these have to be changed accordingly in addition to the roll gap when the size of the input specimen varies.
