Abstract
As an integral part of the punch press monitoring research program, the Acoustic Emission (AE) signal emitted from a Minster1 #3 punch press is completely characterized in terms of signal component identification, relative timing and signal amplitude of each component. The AE signal generated during punching is found to consist of three components: initial impact, shear fracture and rupture. Effects of stock hardness are then examined in terms of relative timing and amplitude of those three components. Good correlations are found between stock hardness and the corresponding AE signals (and thus AE counts).
