Technical And Industrial Benefits Of Reconfigurable Fixtures

Good Essays

ABSTRACT Traditionally, in the civil aerospace industry, assembly fixtures are large, bespoke, permanent structures that are costly to both design and manufacture. Additionally, the time to design, manufacture and install a large fixture can be significant with lead times in excess of 24 months. Generally, there is a requirement to reduce costs, reduce the time to market and improve the capacity and flexibility of equipment. This means that while the costs and lead times must be reduced, the utilization of the tooling should be maximized. Due to the complex component configurations and sheer size of the parts, most establishments have not been able to deploy/utilize flexible and reconfigurable fixtures. These fixtures offer the potential to reduce costs and reduce the design times. Late design changes can also be accommodated with minimal time and cost implications. The design, manufacture and installation of a reconfigurable fixture to assemble a wing box section in a research environment are presented in this paper. This tooling demonstrator is then being used to evaluate the technical and industrial benefits of reconfigurable fixtures for aircraft wing assembly. INTRODUCTION Jigs and fixtures are extensively used in assembly of aerospace components. Main assembly fixtures are used for locating major sub assemblies and components, holding them to the required tolerance while assembly operations like drilling, fastening, riveting, deburring, shimming are carried
