12. A 600 mm × 30 mm flat surface of a plate is to be finish machined on a shaper. The plate has been fixed with the 600 mm side along the tool travel direction. If the tool over-travel at each end of the plate is 20 mm, average cutting speed is 8 m/min, feed rate is 0.3 mm/stroke and the ratio of return time to cutting time of the tool is 1:2, the time required for machining will be (a) 8 minutes (b) 12 minutes (c) 16 minutes (d) 20 minutes
In Orthogonal Cutting Model, why chip thickness after cut is greater than chip thickness before cut?

3- Consider the precedence relationship between the activities of an assembly line. Knowing that the cycle time (T) of the assembly line is 10, then: a) Show the activities are assigned to the work station? (Note that you must show which activities are assigned to which stations. Do not give a number of workstations) b) Calculate efficiency and smoothness indices.
b) An orthogonal cutting operation is performed using a rake angle of 15°, and having a chip thickness before the cut = 0.3 mm and width of cut = 2.5 mm. The chip thickness ratio is measured after the cut to be 0.55. Determine the following: i) the chip thickness after the cut, ii) shear angle, iii) friction angle, iv) coefficient of friction, and v) shear strain.

Q.1) An arrangement of three boxes is shown in figure below. Box A weighs 20 N and rests on an inclined plane, while box B weighs 40 N and rests on a horizontal plane. The coefficient of friction between box A and the inclined plane is 0.25, and between box B and the horizontal plane is 0.35. The pulleys are all frictionless. Determine the range of weight of box C for which no motion will occur. -0.7 m 40 N 1 m 0.5 m 0.6 m B 20 N 0.7 m A 4 5
