Abstract
Hard turning operations often demand cutting
tools that can withstand elevated temperatures, high stress, and prolonged
contact with hardened materials. In this context, the performance of Ti (C, N)-based
cermet tools has been extensively explored, particularly in comparison with
coated cemented carbide inserts. Prior investigations report that cermet tools
tend to provide longer tool life under light cutting engagements due to their
favorable thermal conductivity and reduced cutting forces. However, their brittleness
limits their stability when cutting depth increases, making them more prone to
chipping. Wear on cermet inserts generally initiates with the removal of the
softer binder phase, which eventually leads to particle pull-out on the flank
surface. Coated carbide tools, in contrast, exhibit different dominant wear
modes—most notably crater formation driven by diffusion and adhesion processes
at high temperatures. Both tool types show a gradual rise in surface roughness
with extended machining time. Additionally, the thermal load during machining
influences chip morphology; cermet tools often generate less curled and cleaner
chips owing to lower cutting temperatures. This review consolidates these
findings to highlight the influence of coating architecture and material
selection on tool wear behavior and machining performance.
