    摘要: A method of shearing a stated quantity of each of a number of different sized parts from sheet stock wherein the orientation of stock feed alternates in a predetermined pattern, and wherein the parts to be produced are laid out on the stock so that the first two cuts yield a parts blank and at least one cutoff. The parts blank is then sheared into parts, and the cutoff is sheared in two cuts into a second parts blank and the sequence repeated until the starting sheet is consumed.
