GEOMETRIC DIMENSIONING & TOLERANCING
We offer GD&T analysis of the scanned data of the component to be measured.
GD&T (Geometric dimensioning and tolerancing), is a symbolic language used on engineering drawings and models to define the allowable deviation of feature geometry.
It uses a symbolic language on engineering drawings and computer-generated three-dimensional solid models that explicitly describe nominal geometry and its allowable variation. It's an exact language that enables designers to “say what they mean” with regard to their design models.
By employing GD&T to functional features on engineering drawings the designer is able to communicate to the manufacturer how much geometrical imperfection is tolerable before compromising the function of the component.
Where the fit or function of a component is related to the size of a functional feature, the tolerance zone for that feature can be made flexible if appropriate. Controlling the functional features this way and allowing greater dimensional flexibility elsewhere on the component eases the manufacturing process and consequently reduces the cost of manufacture. The likelihood of producing scrap product is also reduced which leads to a further cost saving.
The GD&T we processes we use are based on ISO1101 and ASME Y 14.5 standards.
