Force-controlled Adjustment of Car Body Fixtures – Verification and Performance of the New Approach

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.
