This paper studies systematically the straightening process of a bar in a two cross-roll straightener. A mathematical model on the precision of the straightened 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 iterative 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 quantitative model is found to coincide excellently with the experimental results and is proven to be effective after successful applications in industrial designs.
