摘要： A method of manufacturing a panel using an initial die and a series of secondary dies includes sequentially defining multi-dimensional models for the series of secondary dies. The method includes simulating a geometry of an nth pre-panel, defining a multi-dimensional model of the nth secondary die based on the simulated geometry of the nth pre-panel, simulating operation of the nth secondary die on the nth pre-panel to determine geometry of an (n+1)th pre-panel, and determining a deviation between the simulated (n+1)th pre-panel and a target pre-panel geometry. If the deviation is outside tolerance, the method includes iteratively: adjusting the multi-dimensional model of the nth secondary die, simulating operation thereof to determine an adjusted simulated geometry of the (n+1)th pre-panel, and determining a deviation between the adjusted simulated geometry of the (n+1)th pre-panel and the target (n+1)th pre-panel, until the deviation is within the tolerance limit.

摘要： A method for forming a stamped component from a blank material with an industrial stamping machine during a stamping process includes measuring a plurality of parameters of the stamping process. The parameters are provided as variables of the stamping process. The method further includes analyzing, by a stamping process model, the plurality of parameters to adjust the stamping process for the blank material, defining, by the stamping process model, a control parameter of the industrial stamping machine for the blank material, and stamping the blank material with the industrial stamping machine based on the defined control parameter to form the stamped component.

摘要： A method of forming a hemming tool includes providing a computer generated model of a panel including a flange in an unhemmed position and of a hemming tool including a hemming surface. Hemming the flange with the hemming tool is virtually simulated in the computer generated model. At least one non-conformity is identified along the flange in the computer generated model after virtually simulating hemming. The computer generated model is then modified to a modified computer generated model by adjusting the flange to change the at least one defect. Hemming the flange in the unhemmed position with the hemming tool is then virtually simulated in the modified computer generated model in the modified computer generated model.

摘要： A forming die includes a first die component with a male bead and a second die component with a female bead. The male bead and the female bead form a bead with a reverse bead geometry with the male bead having a groove and the female bead having a protrusion complimentary with the groove such that the protrusion is aligned with the groove when the male bead extends into the female bead. The male bead includes a push surface, a pair of sidewalls extending from the push surface to a main surface of the first die component, and the groove extends inwardly into the rib. And the female bead includes a stop surface and a pair of sidewalls extending from the stop surface to a main surface of the second die component, and the protrusion extends outwardly from the stop surface into the female bead.

摘要： An exemplary die assembly includes, among other things, a first die having a male bead, a second die having a female bead configured to receive the male bead to hold a workpiece between the first die and the second die, and a step in the male bead, the female bead, or both. An exemplary forming method includes, among other things, holding a workpiece between a male bead of a first die and a female bead of a second die, wherein the male bead, the female bead, or both have at least one step.
