It boasts an unique shape edge preparation that resists crater and flank wear
while reducing vibration, even in interrupted cuts, said a statement from Kennametal.
Tool inserts were withdrawn after each continuous cut and were studied under Tool Maker's Microscope for the wear pattern and width of the flank wear
. Flank wear
most commonly results from abrasive wear of the cutting edge against the machined surface.
The types of wear are flank, notch, and crater, with crater and flank wear
being the most regular and predictable ways .
Since the flank wear
of cemented carbide turning inserts was dominant, it was measured every 0.1 m length of cut for the first tests.
In the fuzzy logic approach, If-Then rule statements are used to formulate the conditional statements for prediction which have three grey relational coefficients such as flank wear
, surface roughness and MRR, and one multi response output grey-fuzzy reasoning grade.
The smallest flank wear
was obtained with insert of two layers coating, however the best surface quality was created with multilayer coating.

The end of tool life may be perceived when the average maximum flank wear
of the insert reaches 0.3 mm, and when a maximum flank wear
of any of the cutting inserts reaches 0.3 mm (BERGLUND, 2011).
The coating is claimed to extend tool life and reduce flank wear
on the insert by up to 200 % when compared with most conventional cutting tools.
