Q-3 Three blocks A, B, and C and a grooved block D have dimensions a, b, c, and d as follows:
a = 40.500 0.025 mm b = 52.000 0.075 mm
c = 73.000 0.015 mm d = 165.900 0.250 mm
Parts A, B, and C are standard parts supplied by vendors from the market, but we are to machine part D according to the the width that you are asked to specify.
(a) Determine the mean gap w0 of w and its tolerance.
(b) Determine the mean size of d (d0) that will assure that w ≥ 0.050 mm.
Problem (4): The following limits are specified in a limit system, to give a clearance fit between a hole and a shaft: Hole = 25 (+0.03 )/(-0.00 ) mm and Shaft = 25 (-0.006)/(-0.020) mm. Determine the basic size, tolerance and allowance, maximum and minimum clearances, type of fit.
