• The manufacturing industry is undergoing a significant transformation in the context of Industry 4.0, and production is shifting from mass products to individual products of batch size one. Moreover, the increasing complexity of components, e.g., due to additive manufacturing, makes the testing setups of components even more complex. Due to the low quantities of the components, it is not profitable to build test benches for each individual component to test a large number of different forces and torsions to ensure the needed product quality. In order to be able to test various components flexibly through different motions, we developed a concept to perform robot-based destructive component testing with industrial robots. The six degrees of freedom and the broad working range of an industrial robot make it possible to apply forces and torques to different products. Since industrial robots cannot apply the same forces and torques in all axis positions, a position must be calculated wheThe manufacturing industry is undergoing a significant transformation in the context of Industry 4.0, and production is shifting from mass products to individual products of batch size one.

Since industrial robots cannot apply the same forces and torques in all axis positions, a position must be calculated whe re the specimen can be tested. Therefore, we propose an approach for automatic specimen placement, which includes a format to map applicable forces and torques of industrial robots. Furthermore, we present an algorithmic approach to execute an automatic feasibility check for the required test motions and an automatic specimen placement using an exemplary robot-based component testing bench.…
