Question

answer the following GD&T questions

A hole is produced at a diameter of 1.501". The specified size is 1.500"plusminus.004" and a surface straightness tolerance of .001" is specified. What is the allowable straightness variation on the surface of the produced part? (Show Calculation if applicable) A hole is produced at a diameter of .997". The specified size is 1.000" plusminus 006" and a derived median line straightness tolerance of .003" diameter at MMC is specified. What is the allowable straightness variation on the produced part? (SHOW Calculation if applicable) If a shaft of 1.251" plusminus 001" diameter serves as datum feature of size and the shaft has an axis straightness tolerance of .003" at MMC applied to define allowable variation of the derived median line, at what size would the feature be simulated when it is referenced as a primary datum feature at MMB? (Show Calculation if applicable)

Explanation / Answer

15) Assuming 0.001'' tolerance is specified at LMC which is 1.496'' dia

      Therefore at 1.501'' dia of the produced part, the allowable straightline tolerance is 0.001 + 1.501 - 1.496 = 0.006''

16) Assuming 0.003'' tolerance is specified at MMC which is 1.006'' dia1

    Therefore at 0.997'' dia of the produced part, the allowable straightline tolerance is 0.003 + 1.006 - 0.997 = 0.012''
