Model Name: Multimedia Courseware - General Dimensioning and Tolerances
Model Number: MXBP203
Learning Topics
- General Dimensioning Overview
- ASME 14.5 Rules
- Engineering Drawing Tolerances
- Tolerance Accumulation
Amatrol’s General Dimensioning and Tolerances (GDT) eLearning provides the learner with an understanding of fundamental dimensioning rules, units, types of dimensioning, dimensioning features, and tolerancing methods. The learner studies the ASME Y14.5M-1994 standard for uniform dimensions and tolerances, common symbols used for dimensioning, and tolerance practices for part features.
What is General Dimensioning and Tolerances (GDT)?
There are a variety of terms and symbols used in dimensioning and tolerancing. They help create a precise and understandable system that ensures parts will be manufactured correctly and will fit properly with mating parts during assembly. The system is comprised of the standards that apply to engineering drawings.
What are Features and Dimensions?
A feature is a part of a whole, a prominent characteristic of something. An example of this would be a person’s facial features: his or her eyes, nose, or mouth. In manufacturing, a feature is a general term used to describe a physical portion of a part, such as a face, hole, slot, pin, or tab.
A dimension is a measurement, usually expressed in inches or millimeters, used to define the shape, size, or location of a feature. Dimensions on an engineering drawing should be read as the expected size, location or orientation of features or features of size. How they look depends on whether they are in millimeter or decimal inch units. Since the formats are very similar, the type of measurement used is always noted on the engineering drawing.
