MONITORING OF METAL FORMING BY ACOUSTIC EMISSION

D. Barschdorff, H. Haupt

Abstract

A new method to supervise metal forming processes with acoustic emission signal analysis is discussed. In forming processes the signals are measured under the presence of typical noise and machine induced impulses which complicate an interpretation. A system is defined to filter the signal with an adaptive algorithm and to eliminate disturbing signal components. The method was verified using measurements of a deep drawing process manufacturing cylindrical parts. The results are presented.
