AB MicroScan 600-1 is a digital Barkhausen noise analyzer. It is designed for fast nondestructive surface quality control and subsurface layers of machine parts from ferromagnetic materials and for evaluating of defects which are caused by changes of residual stresses. By the instrument based on an analysis of the Barkhausen noise is determined the value of magnetoelastic parameter. Experiments which evaluated the influence of different types of process fluids to the machining process and technological properties of the machined parts from constructional steel 16MnCr (CSN 14 220) were carried out in the laboratory of the Department of Machining and Assembly at TU in Liberec. Turned, milled and grinded test samples by using five different types of process fluids were evaluated using the analyzer. For The comparison was machining carried out also without inlet process fluid, i.e. "dry" and with the process fluid - water. Measurements of magnetoelastic parameter were performed repeatedly and measured values were statistically processed. The paper presents the resulting values of this parameter showing the influence of process fluids on the properties of the surface layer of the machined parts.
