Q.2 Graph for abrasive jet machining for the distance between the nozzle tip and
work surface (l) and abrasive flow rate is given in figure.
It is clear from the graph that the material removal rate is first increases because
of area of jet increase than becomes stable and then decreases due to decrease in
jet velocity.
2. Match the following metal forming processes with their associated stresses in the
workpiece.
(A) 1-S, 2-P, 3-Q, 4-R
(B) 1-S, 2-P, 3-R, 4-Q
(C) 1-P, 2-Q, 3-S, 4-R
