Production technology in modern car body assembling is affected by highly automated and complex facilities. However, in mounting car body assemblies adjustments are al-ways necessary to react on process instabilities. Today these adjustments are made according to experience and with a high content of manual operation. On CATS 2014 a new approach was shown that analysis the deformation energy of the input parts. Based on this a mathematical model was
recommended. This model is able to calculate adjustment ways also for high-graded over-determined fixtures of instable sheet metal parts in times below one second. For the first time ever the basics for a fully automated quality process in car body assembling are shown. The paper 2014 described the approach in a theoretical way. This paper will discuss the verification and performance of the approach.
