Due to the lightweight construction trend among car manufacturers, aluminium die casting is gaining in importance because it allows complex contours to be realized and components can be recycled. The disadvantage of aluminum die-cast parts is that the structural parts do not lie within the specified tolerance ranges after heat treatment (the die-casting process) and therefore require manual post-processing in the form of measuring and aligning these parts.

GTech's aim was to develop a self-learning system in which structural parts are measured fully automatically and simultaneously aligned in the three-dimensional range based on the measured values obtained. Another objective was to create a database in order to be able to compare the results of a measuring master with the real measured values and thus draw conclusions about the measuring master model. In addition, the system was to be set up in as small an area as possible. In addition, the system was developed on a modular basis. Each system is designed specifically for the customer and their requirements. The newly developed 3D straightening tool is modified and adapted accordingly at the positions in contact with the workpiece. The basic system remains 95 percent untouched and a 100 percent degree of automation is possible.

In the future, the system can therefore be supplemented by fully automated loading and unloading systems and thus perform its work in a production line equipped with upstream or downstream process steps without human intervention. GTech has already been established for several years in the field of measuring and manual straightening of structural parts (aluminum/magnesium die-cast parts such as strut domes or side members) in the automotive industry. In contrast to manual straightening, in which the structural part is clamped, measured and then straightened by the machine operator with straightening tools to the required tolerances, these individual process steps are performed entirely by the system. In addition, the system not only straightens individual reference points, but also ensures that the parts are straightened across the entire contour in the three-dimensional range. Customers benefit from an increase in productivity, a simultaneous reduction in rejects, shorter cycle times, higher process reliability with greater process stability and fewer quality defects.

Based on the positive patent search carried out in advance, an application for an Austrian patent was filed in the first instance, which was granted. In order to protect this development in our main markets, the patent was extended to the entire EU area. as
