“…Furthermore limited amount of adherent material imply attrition wear mechanism. While the cause behind notch formation was found different, the acting mechanisms of adhesion and attrition comply with finding by Xiao et al [13].…”

“…Formation of the secondary notch, which is located outside of chip contact area, on the opposite, has a major contribution from adhesive wear mechanism. Notch model by Xiao et al [13] on the burrs being responsible for the formation of notch outside chip area didn't find support in the current experiments. Formation of the secondary notch in this study is attributed solely to the effect of chip curl-back.…”

“…Similarly, Xiao et al [13] also detected generation of a notch in the region outside chip area but on the major cutting edge. The phenomenon was attributed to the formation of burrs and their extension outside the cutting zone.…”

“…Formation of the DOC notch is considered to be determined by high gradient of thermal and mechanical stresses [10]. Other mechanisms involve adhesive wear associated with micro welds accompanied by tool material pluck out [11] and attrition wear, both by work-hardened edges of chips [12] and burrs formed at DOC line [13]. Minor notch is also an inherent wear mode when turning Alloy 718 with pure and whisker reinforced alumina [8], mixed alumina and Si 3 N 4 based ceramics [1].…”

AbstractThe paper is aimed on identification and characterization of wear mechanisms of SiC whisker reinforced alumina when turning aged Alloy 718 under different cutting conditions and when machining dry and with coolant. Secondary and back-scatter electron microscopy accompanied by focus ion beam milling and EDX techniques were used for analysis of worn-out tools. Notch wear on the major cutting edge was found to consist of two notches: depth-of-cut notch and secondary notch located outside the chip area. The last was found to be governed by adhesion and attrition associated with adverse chip flow conditions. Formation of minor notch was related to attrition by the defects found on the machined surface. Diffusion of Ni, Fe and Cr into SiC whiskers was found to degrade them and facilitate adhesion. Chemical wear mechanisms were found to be responsible for degradation and decomposition of whiskers and formation of tribolayer on tool surfaces, which in turn was related to the reduced adhesion of Alloy 718 on the tool. Cracking on the tool rake and localized plastic deformation were found to further accelerate tool deterioration.

“…Investigations of Xiao et al (2010) showed that while turning a nickelbased alloy (inconel 718) notch wear developed after prolonged cutting at the major cutting edge, but was located slightly above the depth-of-cut-line. They assumed the periodical impact of the fin-shaped chip and the sawtooth-shaped burr result in a fatigue damage of the major cutting edge in a zone above and around the depth-of-cut-line.…”
