Wear mechanism of a coated carbide tool in cryogenic machining of AISI 4340 Academic Article uri icon

abstract

  • Purpose The purpose of this study is to investigate wear mechanisms of a multi-layered TiAlN/AlCrN-coated carbide tool during the milling of AISI 4340 steel under cryogenic machining. Design/methodology/approach The wear progression was measured using a toolmaker microscope and an optical microscope. Later, a field emission scanning electron microscope and energy-dispersive X-ray analysis were used to investigate the wear mechanisms in detail. Findings A comprehensive analysis revealed that the main causes of tool wear mechanisms were abrasion and adhesion wear on the flank face. Originality/value The investigations presented in this paper may be used by the machining industry to prolong the tool life at higher cutting speed by the application of liquid nitrogen.
