The piece of material from which the workpieces or blanks are cut. If the workpieces are available in the desired size, the stock dimensions will equal those of the workpiece. However, a larger piece of bar stock or sheet stock is typically purchased and the workpieces are cut from it. The number of workpieces that can be cut from a piece of stock depend on the workpiece size and other spacing parameters (sheet border, web width, bar end, cutoff width, facing stock).
