Popis:	The process of turn-milling was a subject of intensive research in the late 1980s, which was followed by a number of practical applications. However, this process has not been investigated as extensively as other conventional cutting processes (turning). The main limitations preventing wider use have been the kinematics (smaller shape elements) and the dynamic instability. This paper presents guidelines showing how to avoid dynamic instability by using optimum entry—exit conditions which can be achieved through a proper set-up of the process parameters. As a result, a decision diagram is proposed. The paper also presents the results of comparison with turning, showing that, at the same productivity, turn-milling enables better surface roughness and is much more suitable for high-speed cutting (HSC) machining than turning, where the centrifugal force restrains the process.
