AB  - This paper deals with the assessment of the impact of the semi-finished product hardness and the cutting conditions of machining process on the surface roughness of the workpiece after machining. The paper shows that the hardness of the material machined layer and also its inhomogeneity have an impact on the resultant quality of the machined surface. The appreciable impact on the surface quality has also the cutting conditions size affecting at the same time the machining temperature. The machining process took place in the company WIKOV MGI J.S.B. in Hronov on the machine Hedelius BC 100 with the face-milling cutter that was attached with the replaceable cutting tips made from the sintered carbide by the company KENNAMETAL. The machining material was a cast-iron.
