Tolerancing. • Definition: “Allowance for a specific variation in the size and geometry of part." • Why is it needed: No one or thing is perfect ! • Hence, engineers have come up with a way to make things close to perfect by specifying Tolerances ! – Since variation from the drawing is inevitable the acceptable degree of variation
Geometrics is the science of specifying and tolerancing the shapes and locations of features on objects. Once the shape of a part is defined with an orthographic drawings, the size information is added also in the form of dimensions. 0 Dimensioning a drawing also identifies the tolerance (or accuracy) required for each.
Geometric Dimensioning & Tolerancing (GD&T). GD&T is a means of dimensioning & tolerancing a drawing which considers the function of the part and how this part functions with related parts. This allows a drawing to contain a more defined feature more accurately, without increasing tolerances. GD&T cont'd. GD&T has
Principles of Inspection. The goal of this part of the course is to describe the different types of geometric tolerances and how actual parts can be inspected to ensure compliance. At the end of this part of the course you will be able to interpret a drawing or model containing GD&T symbols and know (in principle) how to verify.
