a)Which of the seven basic chip formation processes are singlepoint and which are multiple point?
b)Why is metal cutting shear strain such an importantparameter?
c)Why does the cutting force Fc increase with increased Feed orDOC?
d) The cutting conditions in a turning operation are: v = 2.1m/s, f = 3.5 mm/revolution, and d = 0.24mm. The tool rake angle = 5which produces a deformed chip thickness tc = 0.5 mm. Determine:(a) shear plane angle, (b) shear strain, and (c) material removalrate. Use the orthogonal cutting model as an approximation of theturning process.
