Jigless assembly is an approach towards reducing the cost and increasing the flexibility of tooling systems for aircraft manufacture through the minimisation of productspecific jigs, fixtures and tooling. A new, integrated methodology has been developed, which uses a number of building blocks and tools, to enable design for jigless assembly as a result of a logical, step-by-step process. This methodology, AIM-FOR-JAM, is currently being applied to redesign the Airbus A320 Fixed Leading Edge for jigless assembly, as part of the ‘Jigless Aerospace Manufacture’ (JAM) project.

The shear size and flexibility of the larger airframe parts makes it difficult to imagine assembly without extensive use of hard tooling. Yet, the world of aerospace manufacturing is changing. It is already possible to considerably reduce the amount of external, ‘hard tooling’, especially jigs, through innovative design and the applications of advanced technologies. Jigless Aerospace Manufacture, (JAM), is not a single, mysterious, as yet undiscovered technology. Rather it is a growing number of related and linked technologies. Many of these are already well established and considered ‘robust.’ This paper sets out to review and describe some of these enabling technologies and to explain their individual roles towards achieving JAM.
