ABSTRACT

Fig. 3.13 Chart recording of mill speed and deviation from nominal finish thickness of tandem cold mill.

3.6 Width Tolerances

Width tolerances are usually specified as positive deviations from the nominal value. The tolerances for the products with mill edges are distinctly differentiated from the tolerances for the products with cut edges. The width tolerances generally increase with an increase in width and are also greater for highstrength materials as shown in Figs. 3.14 through 3.21.
