Abstract
This paper studies systematically the straightening process of a bar in a t wo cross-roll straightener. A mathematical model on the precision of the st raightened bars is developed. It considers the straightening process to be a continuous alternating bending and reverse bending process. The solution for the residual curvature of the straightened bars involved is an iterativ e function in the mathematical treatment. The precision form of the bar is to be virtually produced to its final shape after it has been straightening severely, using a self-developed prediction model. The developed quantitat ive model is found to coincide excellently with the experimental results an d is proven to be effective after successful applications in industrial des igns, (C) 2000 Elsevier Science S.A.
