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
Answer: Option 1
Sensible Heat Ratio - SHR - is defined as the sensible heat or cooling load divided by the total heat or cooling load.
SHR = qs / qt
=...
Answer: Option 1
Fourier's law of heat conduction is k. A. (dT/dx)
where Q = Amount of heat flow through the body in unit time, A = Surface area of heat...
Answer: Option 3
The narrow zone surrounding the shear plane in machining is termed as primary shear zone.
The area surrounding the chip-tool contact region is called the secondary deformation zone.
This...
