The Attempt at a Solution

a = 4.99mm
b = 10.01mm

So for 'a', to find the minimum possible nominal diameter for line-to-line interference, I assumed the diameter of the smaller bore to be 4.98mm. Also, there's a concentricity constraint of 0.01mm which is as low as it gets, and so minimum = 4.99mm

For 'b', to find the maximum nominal diameter for line-to-line clearance, I assumed the diameter of the largest bore to be 10.02mm. Again, applying the concentricity constraint, it'd be 10.01mm.

I just want to check if I understand the concept correctly.

Hi there,

Your understanding of the concept is correct. The minimum nominal diameter for line-to-line interference is determined by the smaller bore diameter, taking into account the concentricity constraint. Similarly, the maximum nominal diameter for line-to-line clearance is determined by the larger bore diameter, also taking into account the concentricity constraint. Keep up the good work in your calculations and analysis!
