Title: System and method for accumulative double sided incremental forming

A forming system includes first and second tools, moving assemblies, and a control unit. The moving assemblies move the first tool and the second tool relative to the sheet. The control unit is configured to control movement of the first tool and the second tool by the one or more moving assemblies by moving at least one of the first tool or the second tool in a first deformation direction to deform the sheet, then moving the first and second tools laterally relative to the sheet to a subsequent location while engaging the sheet, then moving at least one of the first tool or the second tool in the first deformation direction or an opposite second deformation direction to deform the sheet, and then continue moving the first and second tools to deform the sheet in order to create a three-dimensional component from the sheet.
