Abstract

The influence of coating thickness on the life of TiN-coated high speed steel cutting tools has been studied using planing and turning as machining test methods. In the cutting tests using constant cutting conditions, the thickness of the coating was found to have a significant effect on tool life. In the planing tests a coating of thickness 2–3 μm was found to give the longest tool life. In the turning tests the tool life increased with increase in coating thickness.

The chemical composition of the TiN coating was also found to affect the tool life. Coatings containing less free titanium in the turning tests had four times better wear resistance.
