Effect of Contact Friction on Widening During Forge Drawing and Rolling,
Abstract
Determinations were made of the dependence of widening and lengthening on feed in drawing under flat hammer blocks with different friction coefficients and also of the dependence of widening and lengthening on feed at different degrees of deformation. Reduced formulas and graphs indicate that the friction, both in rolling and in drawing, increases the widening only at large 'feeds', i.e., when the length of the area of deformation is greater than the width of the strip and decreases the widening when the length is smaller than the width.
