Geometrical dimensioning and tolerance (GD&T) Is a system that is used by engineers to communicate the tolerance. GD&T uses a symbolic language that is on the engineering drawings, and other computer generated that are three dimensional solid, and they describe the nominal geometry and the variation that can be allowed. GD&T used by manufacturer of machines to know the degree of accuracy and precision that is required on very controlled component of the part.
Importance of GD&T
Understanding of GD&T helps to read the drawings for the engineers and helps one to know what has to be machined carefully. That is the ...
