... productivity of carbide, cermet, and ceramic cutting tool materials used in machining operations. The useful life of cutting tools may be limited by a variety of wear processes, such as crater wear, flank wear or abrasive wear, builtup edge, depth-of-cut notching, and thermal cracks. The article provides...

...), titanium carbide (TiC), and aluminum oxide (Al 2 O 3 ) were added to enable still higher metal removal rates to be achieved. These coatings enhance the wear and crater resistance of cemented carbides with a modest loss in strength. As a result, a major portion of the market in cast iron, steel...

Along the clearance surface, the tool motion and high normal stress have increased the area of contact between the tool and work, producing flank wear. Lastly, the cutting edge radius has increased...

Cutting tool failure may be managed by removing the cutting tools from the tool holder and measuring flank wear and/or crater wear ( Fig. 1c ) with a toolmaker’s microscope. An end-point measurement is normally established by tool-life testing. Kendall...
