The turning machinability of two magnesium alloy bars, AZ31 and AZ80, was evaluated under various conditions using two types of cemented carbide tool, type 31 and type 33, with two rake angles, γ=6° and 12°. According to the results, there was no difference in the cutting resistance between the two samples for all cutting conditions. However, the cutting resistance was dependent on the cutting speed; it increased with the increase of feeding speed. Also, the feed force increased when a side cutting edge angle was applied. In both specimens, the actually machined surface roughness was smaller than the values theoretically calculated. Judging by the chip shape, the ease of processing was either good or acceptable except for the cases in which the feeding speed was small and the cutting speed was high.
