This is a subjective question, hence you have to write your answer in the Text-Field given below. (a) Using a neat figure show continuous with built-up edge chip formation in metal cutting. Explain how it is formed. (b) In orthogonal machining the tool has rake angle 10, chip thickness before cut is to =0.02 in, and chip thickness after cut is tc =0.04 in. The cutting and thrust forces are measured at Fc=300lb and Ft=270lb while at a cutting speed of 200ft/min. Determine the chip thickness ratio, shear plane angle and machining shear strain. [2+3=5]
