Hole A has to be mated with a Shaft B in a clearance fit type of assembly. Control studies indicate that actual manufacturing distributions are normal with the process for Hole A centered at 6.020 mm with a standard deviation 0.015 mm and Shaft B centered at 5.955 mm with a standard deviation 0.010 mm. Clearance requirements for the assembly is required to be within 0.03 and 0.07 mm (with an average clearance of 0.050mm). It appears that the present process settings will yield more assemblies with excessive clearances than those with insufficient clearances. (a) Calculate the proportion of assemblies that are expected to be too loose and too tight. (b) (12 marks) If it is easy to reset the shaft producing process, what should be the new Mean setting required. so as to correct the imbalance in part (a)? What would be the proportion of assemblies that are (8 marks) expected to be too loose and too tight after resetting? Hole A has to be mated with a Shaft B in a clearance fit type of assembly.
