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 Y14.5-2018 (recently revised from the 2009 edition). 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 – – most notably, the deletion of concentricity and symmetry. The material is reinforced with many practice exercises.


By participating in this course, you\’ll 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

Predpokladané znalosti

Táto časť nie je lokalizovaná

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.
