Question

b) What is the complexity or information content (C) of the pully shown in Problem 1? Assume that the dimensions with no tolerances indicated have tolerances of ±0.010 cm

c) If the tolerance surfaces on the pully in Problem 1 must have a maximum roughness of R = 0.0001cm, what final machining process should be used on these surfaces?

1. It is desired to manufacture the small pully shown below from a medium carbon steel Three possible primary processes for beginning the manufacture of the pully are sand casting, closed die forging, and powder metallurgy. Using the process selection charts, P1, Pl(a) and P1(b) determine which of these processes is feasible. I .00 1.00 500-0.002 0.25040 002 8.00 2.000-0.002 4.00 10.000±0.002 2.000 ±0.002 Dimensions are in cm.

Explanation / Answer

1) Forging is suitable to make this pulley as it is made of steel and medium sized.

2) This pulley needs precision machining

3) Lapping is the final machining process as the requirement of precision of surface finish is high
