INVESTIGATION OF WEAR RESISTANCE OF ROUTER CUTTERS COATED DIFFERENT ANTIWEAR COATINGS
AbstractThe article presents the investigational results, which show resistance of solid tungsten carbide (WC) router cutters
not coated and coated by titanium carbonitride (TiCN), chromium nitride (CrN) and diamond-like carbon (DLC) coatings, to
wear. The tests were carried out using the oak wood samples, which were down milled in the CNC machining center by two
different milling tests. The resistance of cutters to wear was assessed optically through measurement of the helical cutting edge
width. The cutting edge width was measured in the set intervals of cutting path. The received results revealed that the router
cutters coated with CrN are the most resistant to wear. The router cutters coated by TiCN and DLC are less durable. The WC
router cutters, which are not coated at all, are the least resistant to wear.
