Join Kipp Bradford for an in-depth discussion in this video Verification and validation of final part specs, part of Geometric Dimensioning and Tolerancing.
- [Instructor] For simple surfaces,…geometric tolerances can sometimes be evaluated…with a dial indicator.…For example, the flatness of a surface can be indicated…by mounting a dial indicator above a surface plate,…and moving it parallel…to what the perfect surface should be,…while the part is held fixtured to that surface plate.…This technique can prove difficult for more complex parts,…so other methods should be considered.…One of the most direct methods…to verify the tolerance of a part,…is through the fabrication and use…of a go gauge, or a no-go gauge.…
The go or no-go gauge…is designed to mate with the manufactured part.…Any feature of the manufactured part…that is outside of the specified tolerance zone,…will prevent mating with the gauge.…The gauge must be fabricated more precisely…then the part being evaluated.…Typically, gauge tolerances will be 10% of the tolerance…given for the manufactured part being evaluated.…Another common method…for verifying the geometry of a manufactured part,…is the use of a coordinate-measuring machine.…
