The global competition challenges aircraft manufactures in high wage countries. The assembly of large components is very difficult and distinguished by fixed position assembly. Many complex assembly processes such as aircraft assembly are manually done by highly skilled workers. The aircraft manufactures deal with a varying number of items, increasing number of product variants and strict product requirements. During the assembly process hundreds of clips, ties and stringers as well as thousands of rivets must be assembled.To remain competitive in global competition, companies in high wage countries like Germany must insure a continuously high productivity and quality level. To achieve a reduction of cycle times with a simultaneous increase in quality, supportive assistance systems for visual support, documentation and organization within the assembly are required.One example for visual assistance systems are laser projection systems. As a part of the research project IProGro (innovative production technologies for large components) at ZeMA, the abilities of visual assistance systems are expanded in order to enable efficient and quality-assured assembly processes for various production processes.
