Fundamentals of GD&T for Inspectors - Foundational Level

This 2-day foundational-level course builds on geometric dimensioning and tolerancing fundamentals and teaches an introduction of how to inspect GD&T requirements. 

The course offers an explanation of the geometric symbols, rules, and concepts, the datum system, and how to inspect GD&T requirements using tools from the four categories of inspection tools (CMM; comparison instruments and fixed gages; hand tools and open set up; and production gaging systems).

Each attendee receives:
  • A Fundamentals of GD&T for Inspectors Workbook
  • The Fundamentals of GD&T (ASME Y14.5M-1994) textbook by Alex Krulikowski
  • A GD&T Ultimate Pocket Guide (1994)
  • Class handouts

Newly acquired learning is reinforced throughout the class with numerous practice problems. The scope of the workshop includes how to locate a part for CMM inspection but not how to program the CMM to gather the data point.

What Will You Learn

After completing this class, you will be able to:
  • Describe inspection and engineering drawings
  • Explain key terms used in GD&T and how they affect interpretation and inspection
  • Recognize the modifiers and symbols used in geometric tolerancing
  • Interpret and inspect Rule #1,Rule #2, flatness, straightness, circularity, cylindricity, perpendicularity, angularity, parallelism, concentricity, symmetry, circular and total runout
  • Explain the concepts of basic dimensions, virtual condition, inner and outer boundary and bonus tolerance and their effects on inspection
  • Interpret and simulate planar datums and datum targets for inspection
  • Interpret and inspect feature of size datums RFS and MMC
  • Explain the fundamental concepts of tolerance of position: definitions, conventions, advantages and interpretations and their effects on inspection
  • Interpret and inspect tolerance of position RFS, MMC, and special applications
  • Describe functional gages for tolerance of position (MMC) applications
  • Explain profile tolerancing
  • Interpret and inspect profile of a surface and profile of a line applications
