A sheet material machining system includes a sheet material machining machine which is configured to machine a workpiece to produce a machined workpiece that includes a plurality of products and a residual material. The machined workpiece is configured to be placed on a sorting table. The plurality of products are configured to be placed on a temporary placement table. At least one product among the plurality of products are configured to be placed on a discharge table. A carrier includes an attracting actuator and a mobile actuator. The order management processor is configured to control the carrier and includes a storage configured to memorize a layout of the plurality of products in the workpiece. The plurality of products are associated with an attracting order.

A first robot (104) is arranged in association with a belt conveyor (101), and performs a first transfer operation of picking up a product such as a blank material conveyed by the belt conveyor (101) and stacking it on a relay table (102). A second robot (108) performs a second transfer operation of transferring a loaded body of a plurality of blank materials stacked on the relay table (102) to a pallet table (103).

The present invention provides a rotating-layering mold whereby a punched sheet is rotated according to a prescribed angle and layered by an upper mold and a lower mold working in tandem, and provides a press apparatus comprising the rotating-layering mold. A rotating-layering mold comprises a squeeze ring in which is provided a holding hole for holding a punched sheet, the squeeze ring being capable of rotating with respect to a lower mold so that an upper outer circumferential surface of the squeeze ring lies along an inner circumferential surface of the lower mold. The rotating-layering mold further comprises a first thrust bearing, a second thrust bearing, and a radial bearing in order to support the rotation of the squeeze ring with respect to the lower mold.

A method and a system are disclosed for making an article of manufacture from a blank defining an internal opening. A stack of blanks are aligned and the internal openings of the blanks in the stack of blanks are machined by a rotary cutting tool to a finished dimension. The blanks are clamped together before machining in a numerically controlled machine tool. The blanks are subsequently formed individually in a sheet metal forming operation in which the inner perimeter of the internal openings is expanded as the blank is formed.
