Investigation of cutting tool diameter influencing wire cutting operation accuracy using several matrix configurations.

Abstract

In this paper there are presented several investiga-tions considering the wire cutting tool diameter which does influence on wire cutting operation accuracy when in the cutting operation it is used various matrix configurations.The investigation consist of true cutting opera-tions, when is used different poison and the matrix diame-ters for cutting the same wire diameter. The second part of investigation consists of determining the mechanical prop-erties of tested specimens. The third investigation part is building Finite element model and making tension test as well as making cutting operation as well as in the first part. The last one part of investigation consists of making 3D scan and comparing result of FEM and real scanned spec-imen. The major investigation achievement is that there were determined three deformed zones in the cut wire strip. This is the same result was gained in the FE model as well. So the model showed relevant and reliable results for making judgments on deformed zones in the real specimen.
