Abstract
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.
