This paper studied the formulation of chip in high-speed milling of A6061 aluminum alloy. To verify the chip formation and microstructure, experimental results of the chip morphology were derived. To verify the fprmation and microstructure of the chip, experimental results of the chip morphology was performed using SEM. Then, the effects of cutting parameters on the width and structure of free-surface of the chip were examined. The deformability of material and interaction at the tool-chip contact were also identied. The experimental results showed that high-speed milling produced serrated chip, which was significantly affected by the friction at tool and chip contact.
