AB This work deals with the problem of cutting conditions effect on a formation of surface layers, which influences the attributes of the final component surface. The effect of cutting the tension in surface layers examination was carried out. The observation of the surface layer tensions in the component machined by sharp and dull cutting edge was compared. The steel ČSN 41 1500 (E 295) was chosen as the tested material. After cutting the components were exposed to the corrosive medium and subsequently their resistance to corrosion was mutually compared. On the basis of this observation was raised a conclusion that the components machined by dull cutting edge show a lower corrosive resistance than the components machined by sharp cutting edge. This fact corresponds with the statement that the measurement of the surface layers tension in these components was provided parallel to the technical literature without reference to the corrosion damage.
