Measurement of Acoustic Emission and Deformations in Laser Cutting of Deep-drawn Sheet Parts

Abstract

The paper treats the results obtained in simultaneous measurements of acoustic emission with PZT AE sensors and of deformations with resistance measuring rosettes carried out during and immediately after laser cutting-out of a deep-drawn sheet product, i.e. mudguard. The presence of a field of residual stresses produced by deep-drawing is characteristic of… (More)
