Geometric Dimensioning and Tolerancing (GD&T)
October 7, 8:00 am - October 9, 4:00 pm$1,200
GD&T is a practical method for product definition that effectively communicates the design intent for manufacturing and quality verification. It is governed by the technical standard ASME Y14.5M-2018 and some other Y14 engineering product definition and related documentation practices. The course introduces participants to the GD&T method, provides 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 some practical exercises.
- 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
