Gradual wear like flank wear, crater wear etc. The first two wear … WebApr 23, 2024 · The rake crater wear had a significant influence on the cutting edge strength, which was evaluated by indicators such as the wear area S, wear depth K T, and distance from the crater wear bottom to the cutting edge L. Owing to the complexity of the crater wear morphology, a white-light interferometer was used to test the relative indicators.
WebAs flank wear increases, cutting forces will increase as well. Crater Wear. Crater Wear occurs when chips strike and erod the rake face. It takes quite a lot of crater wear to degrade the effectiveness of a tool. Built Up Edge. Built Up Edge, often abbreviated as BUE, occurs when the material being machined builds up on the cutting edge. Weben.wikipedia.org
