Abstract: The invention relates to a method for producing a bodywork component of a motor vehicle that has first been shaped and is then thermally surface-treated, said method comprising iterative simulated steps with variable geometric data of tools that are used in the shaping process. According to the invention, a continuous check verifies whether the expected geometric data of the component lies within the permitted tolerance range of the nominal geometric data of the component. If this is not the case, the geometric data and the generation of corrected tool geometric data is modified. This takes place in two stages, the first stage for the shaping steps and the subsequent stage for the process steps of the thermal surface treatment.

Abstract: A crimping device (1) comprising a crimping bed (12) provided for receiving a workpiece (10), a multiaxial manipulator, in particular an industrial robot (2), which has a crimping tool (5) with at least one crimping roller (6) on its hand, is intended to avoid fold formation on the flange (11), particularly during the pre-crimping. To this end, at least parts of the crimping roller (6) have the form of a cone or a truncated cone having an axis of symmetry (27), an apex (26), and an opening angle ?, wherein for the opening angle ? of the cone it holds that 180°>??140°.
