Sažetak

This paper deals with the application of the Barkhausen noise technique in the nondestructive monitoring of hard milled surfaces. The paper discusses strong magnetic anisotropy linked with microstructural transformations of a machined surface with regard to variable flank wear of cutting inserts. Effective values of Barkhausen noise, peak positions derived from the raw Barkhausen noise signals, the shape of hysteresis loops as well as the Barkhausen noise envelopes are compared with metallographic observations and theoretical background regarding the magnetic domains configuration in the near surface region. A possible concept by which hard milled surfaces could be monitored in real industrial conditions in a non-destructive manner is driven by the specific surface state of the microstructure as well as by the magnetic point of view.
