Why Adopt GD&T at Your Company?

There are a number of reasons to adopt GD&T at your company:

Clarity and consistency in the design processGD&T provides a clear and concise method for defining a reference coordinate system on a component or assembly that can be used throughout manufacturing and inspection. This reduces misinterpretations, and the need for costly engineering changes and rework that can result from a lack of clarity.

Dramatic time savingsBy using GD&T, engineers dramatically reduce their need for drawing notes to describe complex geometry requirements on components and assemblies.

Fit with accepted design-for-manufacturing methodsThe proper application of GD&T closely dovetails accepted and logical mechanical design processes and design-for-manufacturing considerations. For example, the allowable variations as defined through GD&T can be directly read, or “imported,” into 3-D tolerance analysis software such as 3DCS.

GD&T Courses Offered by DCS


BASIC GD&T

Working on 2D drawings and designs? This 20-Hour course is a comprehensive GD&T course focused on review of the ASME-Y14.5M-1994 standard. It can help develop and strengthen your skills for dimensioning and tolerancing, as well as improve your current designs by letting you go through them with an ASME certified expert. 


Objectives:

  • Introduce the concepts and some of the language of the Y14.5 standard
  • Further participants understanding of each Y14.5M standard's symbols
  • Develop participants understanding of Datum Reference Frames
  • Material Condition Modifiers, Regardless of Feature Size and Least Material Condition
  • Reasons for Attending: This course is a thorough introduction of the ANSI Y14.5 standards aimed at developing the participants understanding and application of the symbols and standards.

 

Program Outline, Covered Subject Matter:

  • ANSI Y14.5 standards Linear tolerancing versus GD&T
  • GD&T symbolism/ definitions
  • Datum Reference Frames - definition and proper selection
  • Maximum Material Condition "Bonus" Tolerance - definition and how to take advantage

 


ADVANCED GD&T

As a continuation of the previous GD&T course, this 20-Hour course is focused on practical applications of GD&T for real world experience. 

  • Develop participants knowledge of proper Datum Feature selection and specification
  • Enhance participants understanding each of the ANSI/ASME Y14.5M controls and rules
  • Evolve participants ability to calculate functional tolerances
  • for Attending: This program focuses on the application and development of Geometric
  • Dimensioning and Tolerancing in your application, on your drawings.

Program Outline, Covered subject matter:

  • Brief introduction and review of Basic GD&T
  • Review of the more complex controls - composite position, projected tolerance zone, etc.
  • Datum Reference Frames - proper selection and application
  • Calculation of tolerances for maximum cost effectiveness
  • Functional gauge design

Prerequisites: Basic GD&T, or equivalent experience.


Classes are available on demand at customer location or at DCS's Headquarters in Troy, Michigan, USA.
