MULTIPARAMETRIC ANALYSIS OF SURFACE INTEGRITY AFTER TURNING THROUGH BARKHAUSEN NOISE IN RELATION TO TOOL WEAR

Abstract

This paper deals with application of micromagnetic inspection of surface integrity after turning bearing steel 100Cr6 in dependence on increasing tool wear. This paper indicates influence of tool wear on the selected parameters of Barkhausen noise (RMS value, peak position). The analysis also contains measurement of residual stresses carried out by mechanical method and also analysis of microstructure modifications. The results of experiments show that RMS values of Barkhausen noise decreases with the tool wear as a results of increasing compressive stresses formation in the near surface layers. Moreover the structure transformation occurs in these layers for higher values of flank wear VB.
