This paper presents the tribology issue regarding the chip formation in machining medium carbon steel (S45C) using a coated and uncoated carbide tools. The machining parameters under investigation were cutting speed, feed rate, and depth of cut under dry and cryogenic cutting condition using coated and uncoated carbide tools. The chip shape was largely depended on the combination of machining parameters, especially at high depth of cut and feed rate; the favorable chip was produced. Larger value of shear angle results in smaller shear plane area that provides benefits of lower cutting force needed to shear off the chips and lower cutting temperature being generated during the machining process.
