High-speed Machining

Effect [sic] des paramètres métallurgiques sur le comportement d'usinage des alliages 356 et 319 (étude de forage et de taraudage) /

“…This is due to the several advantages of high speed machining offers namely, good surface finish, allowing for the machining of parts with thin cross-sections. 84 However, the higher the cutting velocity, the shorter the contact time between the tool and the hole surface. So that heat produced in the tool-chip contact does not have enough time to affect the surface quality and the dimensional accuracy of the holes produced.…”

Effect of Cutting Speed on the PVD-Coated Carbide Insert in the Machining on Waspaloy

“…These characteristics cause increases in cutting temperature and resultant tool damage, even at low cutting speeds and low feed rates. The machinability of super alloy materials is much more difficult compared to that of steels and stainless steels [3,4]. Although it is one of the most common nickel superalloys used in the aerospace industry, some drawback are noticed and within these the poor machinability is probably the worst one.…”

Alternative Binder Carbide Tools for Machining Superalloys

“…Numerous ceramic coatings (usually TiN, TiC, and/or Al 2 O 3 ) on the WC-Co base have been examined [19][20][21][22][23][24][25]. Most studies show that the coatings do uniformly extend the life of the carbide tools, especially for steel and iron cutting applications, though one [26] found no benefit on titanium.…”
