Question

The predominant wear occurring in cemented carbide cutting tools is:

• A. Crater wear
• B. Spalling
• C. Flank wear
• D. Surface roughness

Hint:

Flank wear is a result of the frictional forces and high temperatures in the cutting zone.

Answer 1

The Correct Option is C

1. Wear in Cemented Carbide Tools:
Cemented carbide tools exhibit wear during cutting operations, and the most common wear mode in these tools is flank wear.
2. Why Flank Wear:
Flank wear occurs on the side of the tool where the cutting edge comes into contact with the workpiece. This wear is most prominent in cemented carbide tools during continuous cutting operations.
3. Other Types of Wear:
Crater wear (Option 1) is more common in high-speed steel tools than in carbide tools.
Spalling (Option 2) refers to larger pieces breaking off the tool, which is less common in carbide tools.
Surface roughness (Option 4) refers to the finish of the workpiece, not the tool wear.
