Summary on Grant Application Form
The subject of the proposal is laser forming (LF), realised by introducing thermal stresses into the surface of a workpiece with a laser beam to induce plastic strains that result in local elastic-plastic forming. The overall aim is to develop LF as a flexible fabrication technique for three-dimensional components without mechanical contact and hence avoiding expensive hard tooling. The project is stimulated by the needs of the aerospace industry, at British Aerospace (BAe) and Rolls-Royce (RR), who have identified with us in preliminary work the potential of LF to provide a new manufacturing technology that would allow for the redesign of key components (with cost and reduced time to market advantages) and allow the adjustment and alignment of parts by new means. A primary objective is to understand the LF process to implement it for practial applications by a series of experiments and modelling. information will be extracted from the experiments by in-process and inter-operational monitoring. The results of the experiments and modelling will be used to determine the extent to which in-process control will be required for practical applications. The project will culminate in practical LF systems for futher development by BAe and RR.
