This course is an introduction to the Y14.5 standard, focusing on the what, when, why, and the how of GD&T.
This program is designed for anyone who designs, drafts, engineers, purchases, manufactures, estimates, or inspects parts and assemblies. Particular emphasis is placed on those who design and manufacture, and those responsible for quality.
- Introduce the concepts and the some of the language of the Y14.5 standard.
- Enable participants to understand each of the Y14.5 standard’s symbols.
- Bring participants to a fundamental understanding of Datum Reference Frames.
- Understand the definitions and the effects of Material Condition Modifiers.
- Begin to prepare the participants for the ASME GDTP certification exam.
What is the difference between our 2-day class and our 3-day class? In both offerings the student is trained in important dimensioning concepts. However, the primary difference is the 3-day class affords the student opportunity to cover each topic in more depth.
- Objectives and basic overview
- History of Geometric Dimensioning and Tolerancing
- Comparison of the “traditional” method – Coordinate Dimensioning – to the Geometric Dimensioning approach
- Demonstration of GD&T’s Strengths and Advantages:
- As a Design Tool
- As a Manufacturing Aid
- As an overall Communications Facilitator
- General Rules of Dimensioning and Drafting per the Standard:
- Tolerance Zones
- Comparison to Existing Systems
- GD&T Symbology:
- Definitions of all 14 geometric controls
- Modifiers and other symbols
- “Bonus” Tolerances
- How to take advantage of them
- Datum shift
- Datum Reference Frames:
