| 2D Hole/Shaft Bonus Tolerance Example |
 |
|
GDT dimensioning of holes (and shafts) provides a powerful method for increasing inspection yield without trial and error fitting or binning. This method is what is known as bonus tolerancing.
In the following series of figures, the captions suffice to explain the logic. What is being shown is how increasing the size of a hole above MMC allows a bonus in the size of the positional tolerance zone. Figure 2.13  Figure 2.14  Figure 2.15  Figure 2.16  Figure 2.17  For a continuation of this discussion concerning virtual condition, see 2D Virtual Condition. |
