A Common Language of Quality & Design
Available for Groups only
This course is intended for anyone beginning a new implementation of GD & T as well as those seeking to refresh or improve their understanding of the language. Key individuals who will benefit from this course include design engineers, inspectors, machinists, drafters, manufacturing engineers, tool-and-die makers, gage designers and makers, management personnel, and tool designers. Team attendance is encouraged in order to discuss and practice learned techniques upon returning to the facility.
This course teaches terms, rules, symbols, and concepts of GD&T as prescribed in the ASME Y14.5-2009 Standard. Offering an in-depth explanation of geometric tolerancing symbols, their tolerance zones, applicable modifiers, common applications, and limitations; this class includes a comparison of GD&T to coordinate tolerancing; Rules #1 and #2; form and orientation controls; tolerance of position; run out and profile controls. It is up to date with the new 2009 standard and explains all the new rules and symbols. Upon completion of this training, trainees will be able to:
- Explain the importance of standards on engineering drawings
- Describe the types of dimensions, tolerances, and notes
- Explain why geometric tolerancing is superior to coordinate tolerancing
- Interpret the general dimensioning symbols
- Define the key terms used in GD&T
- Recognize the symbols and modifiers used in GD&T
- Explain the rules used in GD&T
- Describe the concepts of worst-case boundary, virtual condition, and bonus tolerance
- Interpret the various types of tolerance (flatness, circularity, cylindricity, straightness, perpendicularity, parallelism, angularity, position, runout, and profile)
- Describe the datum system
- Interpret applications of datum targets, size datum features (RMB), and size datum features (MMB)
