Abstract: An outsourcing service center (7) discloses information obtained through outsourcing services for a first sheet metal processing factory (3) to promote sales. A first ordering customer (5) requests a first sheet metal processing factory (3) to make an estimate for manufacturing a product. The first sheet metal processing factory (3) requests an outsourcing center (7) to perform the work of making the estimate. The outsourcing center (7) logs in to a computer (9) of the first sheet metal processing factory via a computer (15) of the outsourcing center, and, by remote control, works together with the first sheet metal processing factory to perform outsourcing services such as making an estimate and creating NC process data. The processes of these remotely performed services are stored in memory constituting know-how and are then disclosed on a Web page. In this way, examples of previous work successes are introduced and thereby used for promoting CAD/CAM software used in the work processes.

Abstract: A method for processing sheet metal includes processing and forming a sample and a blank on a work while leaving a microjoint part in a blanking process. The method also includes detecting at least one of a plate thickness of the work in an optional position and a spring-back amount of the sample during bending. Information of at least one of the plate thickness and the spring-back amount is transmitted to a controller of a bending machine in a bending process after the blanking process. Bending is performed by calculating a ram control value in bending using data of at least one of the transmitted plate thickness and the spring-back amount.
