Homework Help: Engineering Drawing: Pin/Bore Tolerances

  1. Dec 10, 2012 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations


    3. 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.
