Q32

In metal machining, the work-tool contact zone is a zone where heat is generated due to

A.
Plastic deformation of metal
B.
Burnishing friction
Answer
C.
Friction between the moving chip and the tool face
D.
None of the above

Answer: Option B

Solution

Answer: Option B
Solution:
Burnishing is the plastic deformation of a surface due to sliding contact with another object. It smooths the surface and makes it shinier. In metal machining, the work-tool contact zone is a zone where heat is generated due to Burnishing friction
