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Tool inserts were withdrawn after each continuous cut and were studied under Tool Maker's Microscope for the wear pattern and width of the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 [9].
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.

Multilayer CVD coated and uncoated carbide inserts analyzed in this study with respect to
flank wear and surface roughness.
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.
