Abstract
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.
