Course Overview

  • Learn about the importance of GD&T in the industry.
  • Understand the different GD&T symbols , rules in GD&T , Application of GD&T , Explanation of datums, and all the different type of tolerance.
  • Design and drafting with GD&T application for the Butterfly valve to understand the Application part of GD&T .
  • A brief Idea about all the GD&T concepts are studied. 

Course Syllabus

On a daily basis we talk to companies in the likes of Tata Elxsi and Mahindra to fine tune our curriculum.

Introduction to GD&T

In this module, you will study 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

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

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

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

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

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

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.
