Fundamentals of Geometric Dimensioning & Tolerancing (GD&T) Web Seminar RePlay PD330933ON

Geometric dimensioning and tolerancing (GD&T) is used as a symbolic way of showing specific tolerances on drawings. GD&T is a valuable tool that effectively communicates the design intent to manufacturing and inspection. It is governed by the technical standard ASME Y14.5M-1994, which was updated in 2009. This course introduces participants to the GD&T system, providing a working knowledge of the correct interpretation and application of each symbol, general rules, the datum system, and 'bonus' tolerance and highlighting some of the changes in the updated Y14.5 standard. The material is reinforced with many practice exercises.

Objectives

By participating in this course, you will be able to:

  • Explain the benefits of geometric tolerancing
  • Identify datum features and determine their order of precedence
  • Identify and interpret each of the characteristic symbols
  • Describe the material condition modifiers and how "bonus" tolerance occurs
  • Correctly interpret GD&T feature control frames, and explain the impact on manufacturing and inspection

Materials Provided

  • 90 days of online single-user access (from date of purchase) to the eight session,
    approximately 16 hour, recorded presentation
  • Course workbook (downloadable, .pdf's)
  • Online learning assessment
  • Instructor follow up to your content questions
  • 1.6 CEUs* (upon completion of all course modules and satisfactory assessment score)

*SAE International is authorized by IACET to offer CEUs for this course.

Is this Web Seminar RePlay for You?

This course is ideal for anyone who has a need to apply or interpret geometric tolerances on a product print. Product engineers, manufacturing engineers, CAD designers, quality inspectors, and other engineering and manufacturing personnel will all benefit from a better understanding of design requirements; improved communication with customers and suppliers; and improving designs by taking advantage of bonus tolerance and other GD&T benefits. Participants should have an understanding of basic blueprint reading.

This course satisfies a requirement in the Product Engineering Tools and Methods Certificate Program.
