Fundamentals of GD&T ASME Y14.5M 1994 - Advanced Level
ET2001
- Content
This 3-day advanced-level Fundamentals of GD&T course is an in-depth study of the terms, rules, symbols, and concepts of geometric dimensioning and tolerancing as prescribed in the ASME Y14.5M-1994 Standard. The course can be conducted in three 8-hour sessions or with flexible scheduling including five mornings or five afternoons.
This class includes all the content from the Fundamentals of GD&T 2-day foundational course: an explanation of geometric symbols, including each symbol’s requirements, tolerance zones, and limitations. It compares GD&T to coordinate tolerancing, and explains tolerance zones; Rules #1 and #2; form and orientation controls; tolerance of position; runout and profile controls. Newly acquired learning is reinforced throughout the class with more than 100 practice problems using industrial drawings.
This in-depth, advance-level course also covers- More detailed discussion of terms, concepts, and symbols used in GD&T
- Using tolerances on CAD models
- Discussions of verification principles for each geometric tolerance
- Related and unrelated actual mating envelope
- Functional and cartoon gages
- Examples of inspection methods for each geometric tolerance
- Critical thinking discussion
- 50 additional practice problems using industrial drawings
Newly acquired learning is reinforced throughout the class with more than 150 practice exercises.
Each participant receives:- The Fundamentals of GD&T (ASME Y14.5M-1994) textbook by Alex Krulikowski
- GD&T Ultimate Pocket Guide (1994)
- A GD&T Workbook with Engineering Drawings (1994)
This course provides a complete look at GD&T Fundamentals. For more complex GD&T topics, like the expanded use of composite position and profile tolerances, customized datum reference frames, the translation modifier, and applying GD&T to non-rigid parts, see our Advanced Concepts of GD&T course.
- Content
- By attending this course, you will be able to:
- Describe engineering drawings: importance, drawing conventions, dimensions and tolerances, standards*
- Describe what dimensioning and tolerancing is
- Explain why geometric tolerancing is superior to coordinate tolerancing*
- Describe the key terms used in geometric tolerancing
- Recognize the modifiers and symbols used in GD&T
- Explain the rules used in GD&T
- Describe the concepts of basic dimensions, worst-case boundary, virtual condition, inner and outer boundary, and bonus tolerance
- Interpret the various types of tolerances (flatness, straightness, circularity, cylindricity*, perpendicularity, angularity*, parallelism, position, concentricity*, symmetry*, runout, and profile)
- Describe the datum system
- Interpret applications of datum targets, feature of size datum specifications (RFS & MMC)
- Describe the fundamental concepts of tolerance of position
- Interpret tolerance of position special applications*
- Calculate tolerance of position tolerance values using the fixed and floating fastener formulas*
*Not covered in 2-day foundational-level course
This course teaches GD&T fundamentals. For more advanced GD&T concepts (composite tolerancing, tolerance analysis, datum selection, non-rigid part dimensioning) see our Advanced Concepts of GD&T course offering.
