Objectives and Approach

The objective of this project is to develop a generic prototype which supports the quality of products manufactured in highly automated production facilities. The design of products with a well-known product structure (variant design) will be supported, based on domain-, factory-, and product-related knowledge, feedback from the production environment and product testing, and experience emerging during the use of the system. The RA-IQSE approach will be validated by the installation of the prototype in a manufacturing environment producing shock-absorbers. The prototype will make use of knowledge-based techniques and will incorporate a CAD system in the user interface.

The major items of the project programme are:

Progress and Results

The architecture and functionality of the prototype has been defined and described and generic structures for products, processes and quality aspects developed. Applicable techniques for the knowledge representation, reasoning and man-machine interface building have been studied, and a strategy for implementation selected. The target product and the procedures of the manufacturing environment have been analysed and described, and further knowledge acquisition performed. The major parts of the prototype have been implemented and demonstrated and a set of bench-work test data has been collected.

Exploitation

The prototype will facilitate design work by detecting errors and giving advice on how to correct them, by minimising the number of product prototypes needed during product development, and by giving advice on how to improve the product design according to the available production facilities. This means that the system will decrease the time needed for the development of new products, so that it will be possible to meet changing market requirements more quickly.

Although initially focused on machined components, the project results are expected to have wide application, with the project partners intending to exploit them in the aerospace, process control, textile and carpet industries.
