In metal cutting $$BUE$$ formation results in

Only negative rake angles are used with the following tool material

The heat generated in metal cutting is dissipated in different proportions into environment, tool, chip and work-piece. The correct order of this proportion in decreasing magnitude is (no cutting fluid is use ($$d$$)

Parting-off operation is carried out on a cylindrical work-piece of $$100mm$$ diameter. The groove width is $$2$$ $$mm$$ and an in feed of $$0.2$$ $$mm$$ per revolution is given at a maximum cutting speed of $$60$$ $$m/mm.$$ The specific cutting force for the material is $$800\,\,N/m{m^2}.$$

The tangential force on the tool is
