Cutting fluid has an influence on tool life in cutting in terms of lubrication and cooling. This study compares the cutting processes in milling of 0.45% carbon steel under dry and using 3 kinds of lubrications. The cutting force in dry is less than those of cuttings with lubrications due to thermal softening of material under high cutting temperatures. The dynamic component in milling with FGM408PR is different from those of millings in dry, with EC50T3 and Synthetic#880 due to the change in chip formation. The flank wear rates of bottom edges in milling with FGM408PR are lowest compared to the other conditions. In milling with FGM408PR, the burnt area on the flank face was not observed due to well penetration of the cutting fluid.
