Knowing this it is not surprising to find that several tools have been developed to hold onto the work for cutting.... (2001) Complete Story

Rolling can be thought of as a local, or isolated, deformation process during which thickness is decreased, length increased, and width remains unchanged. Drawing is different from rolling in that the pressure of drawing it not transmitted through the turning action of the mill, but instead depends on force directed locally at the area of compression. This means the amount of possible drawing force is limited by the tensile strength of the material, a fact that is particularly evident when drawing thin wires..... (2001) Complete Story
