PURPOSE:To reduce the machining time by providing multiple recesses on a large plate so that plate-like parts can be contained in sequence and several types of machining portions can be obtained in one shearing. CONSTITUTION:Multiple recesses 4, 5, 6 are formed on a large plate 3. These recesses are formed adjacently to each other so that machining portions A1, A2, A3 of plate-like parts 1 subject to shearing machining are aligned in a straight line at the position of the cutting edge (not shown in the figure) of a shearing machine (not shown in the figure) and other peripheries 1a except the machining portions A1, A2, A3 can be contained with no gap. The parts 1 are shifted to the recesses 4, 5, 6 in that order with their attitudes changed and are machined. |
