摘要： A system, method and software arrangement are provided for generating press-formed parts having a more consistent quality based on improved determination of processing conditions. For example, an apparatus can be configured to compare actual performance values of material properties provided by a material property database with standard values, and to adjust forming conditions such as a forming speed and a blank-holder pressure in accordance with the compared result. A control arrangement can be provided to control a press-forming device using the adjusted forming conditions. Accordingly, it may be possible to reduce occurrences of defects such as cracks and wrinkles when press-forming materials, and to obtain products having consistent quality and substantially identical shapes.
