(e) Briefly describe types of chips that occur in metal cutting.
(f) For orthogonal cutting, the tool rake angle =15°. The chip thickness before the cut is
0.30mm and the cut yields a deformed chip thickness =
0.65mm. Calculate the shear
plane angle and shear strain.
a rod is to be manufactured using turning operations and is made of
Nickel alloy. The rod is 80 mm in length and 15 mm in diameter. The final required diameter is
10 mm and the spindle rotates at N = 500 rpm while the tool axial speed is 100 mm/ min. Calculate material
removal rate, cutting speed, cutting time, the power dissipated, and cutting force.
Discuss the effects of cutting speed, feed rate, and depth of cut on the tool wear rate during a turning operation.
How does each parameter influence the surface finish of the workpiece?
Provide a detailed explanation based on the principles of metal cutting mechanics.
