Introduction to GD&T

Geometric Dimensioning and Tolerancing (GD&T) is a quality control method that is used for defining allowable variation in size, form, orientation, and location using symbols. The purpose of GD&T is to precisely define parts and assembly geometry.

In this course, you will learn about the Siemens NX CAD software for design, assembly, and drafting of parts. You will train in industry best practices for design and drafting for the proper manufacturing of components. You will also learn the application of different tolerance symbols and datums for parts and assemblies with practical examples. You will work on a project that will introduce you to drafting using the GD&T application by designing a butterfly valve.

COURSE SYLLABUS

1Week 1: Introduction to GD&T

In this module, you will study about GD&T and its uses. After your first class, you will be able to understand the basics such as:
  • Difference between traditional dimensioning and GD&T
  • Benefits of GD&T
  • How to read a feature control frame
  • Technical standards- ASME Y14.5M-2009
  • Different symbols used in GD&T, cover, and feature of size

2Week 2: Rules, Symbols, and Form Tolerances

In this module, you will learn about the governing rules of GD&T. After this class, you will have an understanding of:

  • Rule No. 1 (i.e. Taylor principle a.k.a envelope principle)
  • Rule No. 2 (Regardless of feature size)
  • 14 symbols used in GD&T
  • Flatness, straightness, cylindricity, and circularity tolerances
  • MMC, LMC, and RFS conditions
  • Various examples for form tolerances

3Week 3: Datums, Modifiers, Virtual Condition

In this segment, you will study the following topics:

  • What are datums and how to apply datums to parts
  • Datum reference features
  • Datum feature modifiers
  • How to calculate virtual condition
  • Conjugated datums

4Week 4: Orientation Tolerance and Profile Tolerance

At the beginning of this section, you will have built a good base for learning complex tolerances. In this section you will learn:

  • Profile of a surface and profile of a line
  • Perpendicularity tolerance, parallelism tolerance, and angularity tolerance
  • Composite profile tolerance
  • Various examples for orientation and profile tolerances

5Week 5-6: Position Tolerance

Position tolerance is the most widely used tolerance in GD&T.


In this section we will go through:

  • Understanding true position
  • Projected tolerance
  • Composite tolerances
  • Tolerance zones- cylindrical, rectangular, spherical
  • Examples of position tolerance

6Week 7: Co-axiality, Symmetricity, Run-outs

By now, you will have enough knowledge to read an entire GD&T drawing and understand it. In this section, you will learn about some tolerances that are not widely used in the industry but are mentioned in the ASME standard

You will learn:

  • Coaxiality
  • Symmetricity
  • Circular and Total Run Outs
  • Examples

7Week 8: Understanding GD&T Drawing

In this part, you will study complex GD&T drawings and understand every individual tolerance and the message the tolerance conveys.

WHO IS THIS COURSE FOR ?


  • Design engineer designs the components, but before a design is manufactured there will be a dimensional engineer who will provide the manufacturing constraints in the form of GD&T plans to manufacture a part precisely. This course can be taken up by freshers who want to work in the industry as dimensional engineers.
  • Professionals working in the industry can take up this course to enhance their skills.
  • This course helps students and professionals understand where to apply the various GD&T symbols based on the standards for manufacturing and reproducibility of components.
  • Students studying this course will have job opportunities in the automotive and manufacturing domain as a dimensional engineer or a production support engineer. Within experience they can be a GD&T lead engineer.
