Choose an option
-
ANose, front relief face, and side relief face
-
BOn the rake face at a short distance from the cutting edge only
-
CCutting edge only
-
DFront face only (at the very edge)
Answer
Correct Answer: On the rake face at a short distance from the cutting edge only
Explanation
ConceptCrater wear develops on the rake face due to chip flow, adhesion/diffusion, and high sliding temperature—typically forming a crater some distance from the cutting edge where the chip contacts the face most intensely.
Final AnswerOn the rake face at a short distance from the cutting edge only
