Novel low cost vibratory stress relieving of castings

Objective


The project has:-
i) provided direct scientific proof of the ability of VSR to significantly reduce residual stresses in industrial casting types relevant to SME foundries,
ii) as a direct result of the modelling activities undertaken, provided clear evidence (in the form of accurate dimensional stability data obtained under controlled laboratory conditions) on industrial (SME-produced) components of the ability of VSR to be as successful as conventional heat treatment in improving dimensional stability after machining but with the advantage of greatly reduced costs and application times,
iii) demonstrated that current VSR techniques are not successful for all castings and hence that SME foundries cannot simply start applying the technique on a production basis without further development,
iv) demonstrated that low-noise sub-resonant VSR can be as effective as resonant VSR,
v) provided further evidence that VSR does not mechanically damage the components to which it is applied, and
vi) provided the SME foundries (including those with previously limited access to advanced technology) with important information on residual stress effects.
