Final curvature

The result of a straightening process is expressed e.g. by the final curvature of the product to be straightened. Basically there can be two objectives: to create a straight product, i.e. a final curvature of zero within the set tolerances, or to produce a defined final curvature other than zero. Which of these two objectives applies will largely depend on the process which follows the straightening.

To guarantee final products of constant positive quality it is important to produce a final curvature that is as constant as possible. A changing final curvature goes hand in hand with varying process transitions and ultimately leads to final products of fluctuating quality.
