Coatings used for surface engineering of cutting tools play substantial
role in the recent advancement in high performance machining of
hard to cut materials, specifically hardened H13 tool steel. End milling
of 3-D parts is a most frequently used operation.Wet machining conditions
are most widely used on production floor due to a variety of
reasons. With introduction of hard to cut materials to manufacturing
practice cutting tool requires efficient protection fromthermal andmechanical
loads in the cutting zone
