The objective of the present work is to automate the project planning of handling devices as much as possible. This process is presented using the example of the process chain for the production of lightweight parts using the sheet molding compound (SMC) and resin transfer molding (RTM) processes. As a first step, a modular handling device is developed and built-up, which enables a large number of gripper arrangements. This device then makes it possible to measure the resulting deflection of flat parts in the handling process. In order to ensure that it is not always necessary to measure the deflections, a model is built-up with ABAQUS to enable a simulated estimation. Using this simulation model, a design logic for the arrangement of the grippers on any shaped parts is presented. This design logic works in two steps and is based on the approach of growing neural gas (GNG), which is adapted to the problem by implementing additional rules. First, an initial gripper configuration is created based on the geometry of the object, which is then improved by an iterative process of simulation and adaptation. Since the production of lightweight parts often requires more than just one type of sheet, various solutions for the different sheets are combined systematically at the end to form one gripper arrangement and a method is shown concerning how this can be implemented using the previously-developed modular handling device.
