GD&T uses symbols and shapes to tell us what the
designer wants. The symbols have the same meaning
everywhere. Therefore, it is a universal language.
GD&T = Lower Cost
Geometric Dimensioning and Tolerancing properly
applied can reduce production
costs and speedup inspections. Reducing the number
of vague notes on a print makes it easier and
quicker to read.
GD&T allows the maximum tolerance for many features
of product. This reduces the potential for scrap and
that lowers the cost of production.
Datums
Datums tell us where dimensions and tolerances
originate. There should be no guessing as to where
to begin measuring a feature on a part. Datums
provide the reference for setup and inspection.
Bonus tolerance
Two material conditions apply to certain types of
features that allow production bonus tolerances.
These material conditions are maximum material
condition and least material condition. The bonus
tolerance doesn’t affect the dimensional tolerances.
It applies to the size of the tolerance zone.
Enroll in one of our seminars or have an in-plant
class and learn how tolerances can be increased and
retain fit, form and function.
What features can have GD&T tolerances?
Features of form, location and orientation can have
GD&T tolerances. Features such as thickness cannot.
Learn what features can have GD&T tolerances. Learn
the rules and
applications for datums. Discover what features need
datums and how many datums.
You can have this class presented at your business
for as little a $65. per person.
