WebSep 15, 2024 · The results show that crater wear and flank wear are typical failure modes affecting tool life during the continuous cutting process such as turning and orthogonal cutting [20, 21]. Adhesion and abrasion were found to be the predominant wear mechanism for flank wear [20 ]. WebJan 14, 2024 · Crater wear happens on the tool face at a short distance from the cutting edge by the action of chip flow over the face at a very high temperature. The crater wear is mainly due to diffusion and abrasion. It is mainly observed while machining ductile material due to the continuous formation of chips.

WebCrater wear occurs approximately at a height equalling the cutting depth of the material. Crater wear depth ( t0) = cutting depth Notch wear which happens on both the insert rake and flank face along the depth of cut line causing localised damage to it primarily due to pressure welding of the chips. The chips literally get welded to the insert.
