Scheduling and Verification of Micro Assembly Processes

This paper presents the scheduling and verification of automated micro assembly processes for which assembly accuracies of a few micrometers are necessary. To reach these accuracies, a relative positioning strategy was used. Possible solutions for the scheduling and verification of two micro assembly processes carried out by a size-adapted assembly system are introduced. These processes reached a positioning uncertainty on the range of 0.5…1 μm and part dependent assembly uncertainties of 24 μm and 45 μm.
