What is included in the course?

Introduction to GD & T

In this module, you will understand what GD&T is 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, Surface and Feature of size

Rules, Symbols and Form Tolerances

In this module, we will raise our knowledge up a notch and learn about the governing rules of GD&T. After this class, you will have a thorough knowledge 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

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

  • Profile of Surface and Profile of Line
  • Perpendicularity Tolerance, Parallelism Tolerance and Angularity Tolerance
  • Composite Profile Tolerance
  • Various examples for Orientation and Profile Tolerances

Position Tolerance

Position Tolerance is most widely used tolerance in GD&T and hence we will dedicate entire segment in learning this tolerance and its application. In this section we will go through:

  • Understanding True Position
  • Projected Tolerance
  • Composite Tolerances
  • Tolerance Zones- Cylindrical, Rectangular, Spherical
  • Examples

Coaxiality, Symmetricity, Runouts

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

  • Coaxiality
  • Symmetricity
  • Circular and Total Runouts
  • Examples

Understanding GD & T Drawing

In this part, we will go through a complex GD&T drawing and understand each and every tolerance and the message the tolerance conveys
