Making the cut for the contour method

Bouchard, P. John; Ledgard, Peter; Hiller, Stan and Hosseinzadh Torknezhad, Foroogh (2012). Making the cut for the contour method. In: 15th International Conference on Experimental Mechanics, 22-27 Jul 2012, Porto, Portugal.

Abstract

The contour method is becoming an increasingly popular measurement technique for mapping residual stress in engineering components. The accuracy of the technique is critically dependent on the quality of the cut performed. This paper presents results from blind cutting trials on austenitic stainless steel using electro-discharge machines made by three manufacturers. The suitability of the machines is assessed based on the surface finish achieved, risk of wire breakages and the nature of cutting artefacts introduced.
