Abstract:
The
correction of distortion and design shape in manufactured components
is increasingly in demand in industry, in particular for aluminium
components, where the applications for aluminium and its alloys
continue to expand. A process capable of achieving these actions
in an automated, controlled and precise manner would be of significant
benefit to industry. Due to these factors a study has been conducted
on the use of laser forming (LF) as a method of automated distortion
correction. Investigations were carried out into the use of
purely geometrical data from a component as a basis for scan
strategy development. The iterative error based method developed
as part of this was shown to be a significant step towards controlled
3D LF and, as this method relies on the error between a component
and a design shape, it was shown to be ideal for the correction
of unwanted distortion.
