In the figure above, what is the allowable Straightness error permitted for the derived median line? {Ans: 0.6 is the correct answer (0.8 - 0.2). Remember Rule #1 - There must be perfect form at MMC. The Straightness error permitted occurs as the the part departs from MMC towards LMC equal to the amount of departure. Keep in mind that this tolerance is a diameter and that control of the derived median line in this manner is indirect, meaning it is not inspected.}For the pin shown above, what would be the nominal diameter of the functional gauge used to inspect the part? What is the maximum permissible Straightness tolerance? Choose the only answer where both are correct. {Ans: The correct answer is a functional gauge hole diameter of 10.08 and a maximum Straightness tolerance of 0.11. For an external feature, the functional gauge may be found by calculating the Virtual Condition. This is equal to the MMC condition of the part, plus the associated geometric tolerance. ( 10.03 + 0.05 = 10.08) The maximum Straightness tolerance is calculated by adding the listed geometric tolerance to the difference between the MMC and LMC size limits. 0.05 + (10.03 -
