Abstract: The paper makes a comparison between the functional angles at parting by turning and face milling operation where is tahing into account the importance of correct position of the tool. In the same time is shown that at face milling operation in compariosn with turning operation the functional angles have not decisive importance on the cutting process due to small variation of them in comparison to constructive angles.
