  • Method and system for processing plate material, and various devices concerning the system
    Patent number: 7249478
    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.
    Type: Grant

  • Sheet working method, sheet working system, and various devices related to such system
    Patent number: 7040129
    Abstract: An actual plate thickness and actual material constants are measured during punching before bending. The measured information is reflected on the bending, so that the bending is performed efficiently and accurately. Punching is carried out for each blank developed based on a nominal plate thickness and nominal material constants in blanking before the bending of a work W. Then, an actual plate thickness distribution and an actual material constant distribution of the work W are calculated based on various data containing a ram stroke and a pressure detected in the punching.
