METHOD FOR SHAPING FLAT BODIES TO GIVE IRREGULAR MULTI-DIMENSIONAL CURVED OBJECTS
Abstract:
The invention relates to a computer-supported method for the shaping of flat bodies, such a sheets and plates to give irregularly curved, in particular, three-dimensional objects. The above are, for example, sections of ship hulls, housings, vehicle chassis or special containers. The aim of the invention is a method whereby flat bodies, in particular, strong sheet can be used to produce irregular, multi-dimensional, curved objects from the least number possible of individual components whilst maintaining the tightest of tolerances. A further aim is the shaping of large, thick sheets and overcoming the intrinsic resilience. According to the invention, the desired free-formed surface of the object is modelled using the CAD programme, a virtual division of the given surfaces into individual pieces is carried out and the separation of workpiece and tool from the individual support for the adjustable tool at fixed points is determined. The adjustment of the individual supports and the tool is carried out according to the above co-ordinates and the piece pressed in the form. Finally the individual pieces are connected together.
