METHOD OF RESTARTING OPERATION OF PUNCH PRESS MACHINE AND NUMERICALLY CONTROLLED DEVICE

摘要

A function of punching a plurality of products in punch press processing that has been interrupted is adapted to be restarted easily. The processing position interrupted is identified by the product number of the product set on a raw material and the product number of the interrupted product or the product number of the product to be processed next is input to an NC unit (S5). When this product number is input, a command program is changed on the basis of the input product number (S6). The changed program gives a processing command starting in a raw material position of a product other than the interrupted product to the punch press machine, whereby the operation is resumed (S7).
