Sažetak
Flank build-up on HM cutting edges at speeds in excess of approximately 600 m/min may constitute a problem when turning magnesium alloys. SEM analyses of workpiece materials, tool inserts with flank build-up it-self indicate that manganese compounds play an important role in forming very hard practices and through a high degree of attraction to the tool material. Three Mg-Al-Zn alloys with different manganese content were turned under different cutting conditions in order to determine the tool-workpiece interaction at different cutting speeds. Ail three alloys gave the same type of flank build-up, the critical cutting speed which expresses the tendency to form flank build-up, was however different for the three alloys.
