Course Overview
Geometrical Dimensioning and Tolerancing (GD&T) is a language used in mechanical engineering drawings. It consists of symbols that communicate geometry requirements efficiently and accurately for associated features on components and assemblies.
Most engineers understand the geometric symbols, but often, proper definitions are misinterpreted or inconsistently applied. Fully adopting and understanding the philosophy will enable engineers to calculate, apply, and analyse tolerances to guarantee that parts fit together and are totally interchangeable at the design stage before physical parts are created.
Our Training Courses
Part 1: GD&T Foundation
Duration - Onsite: 2 days, Online 3 days
It is essential to clearly understand the philosophy before individual engineers can correctly apply GD&T to the national standards.
Foundation Part 1 will look to:
- Ensure clarity of purpose in the group
- Expose Engineers to the philosophy of GD&T
- To introduce and demonstrate the use of GD&T standards
- To convey an understanding of the meaning of the Geometric symbols
- To illustrate the application of GD&T to specific parts
- Enable you to calculate and display functional tolerances
- Introduction
- Co-ordinate Drawings
- Symbols and terms
- GD&T Rules
- The Datum System
- Form Controls
- Position
- Orientation Controls
- Profile Controls
- Controlling Co-Axial features
- Controlling Co-planar features
- The five-step GD&T approach
- Conclusion
Part 2: GD&T Foundation
Duration - Onsite: 2 days, Online 3 days
Introduce new concepts not covered in Part 1 and expand on previously covered topics. In this session, the delegates will have more practical GD&T exercises to complete.
Foundation Part 2 will look into:
- Making detailed drawings on paper and 2D and possibly 3D detailing within your chosen CAD system, as most of the media within your company will be displayed this way.
- All of the drawings completed must be in accordance with the ISO or ASME Standards.
- Introduction
- 5 Steps for GD&T Implementation
- Group GD&T Exercise 1
- Least Material Requirement
- Tolerancing Patterns of Features
- Drawing Audit
- Inspection Report
- Dimensioning Slots
- GD&T CAD Exercise
- Conclusion
GD&T Application Session
Duration - Onsite: 2 days, Online 3 days
The initial training course will spend time looking at illustrative examples of situations the Engineers face when applying GD&T.
However, our recommendation would be to apply training further through project-specific coaching around commonly faced problems. This approach maximises the impact of the training and subsequent knowledge retention and is a useful element of the evaluation process.
Exercises in this session will give the delegates exposure to advanced GD&T not covered in the foundation session, whether for design, manufacture, or Inspection activities.
