Fundamentals of GD&T for Inspectors Workshop
For CMM operators, inspectors, gage designers, manufacturing engineers, technicians, supplier quality engineers
This 2 1/2-day workshop includes an introduction to geometric dimensioning and tolerancing and how to inspect GD&T requirements. The course is based on ASME Y14.5, Y14.5.1 and Y14.43 standards.

The course explains:

• The geometric symbols, rules, and concepts
• The datum system
• Requirements of the geometric symbols and the datum system
• Each geometric symbol’s tolerance zone shape, size, orientation, and location
• 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)

The scope of the workshop does not include how to use the various inspection tools. For example, the workshop will discuss how to locate a part for inspection on a CMM, but it will not cover how to program the CMM to gather the data point.

Who Should Attend
This workshop is a valuable tool for individuals who inspect parts, create inspection plans, or approve inspection methods. Typical attendees include CMM operators, inspectors, gage designers, manufacturing engineers, technicians, supplier quality engineers.

Workshop Highlights
You’ll learn the basics of GD&T, the ability to interpret GD&T on drawings, and an understanding of several methods for inspecting GD&T requirements. Inspectors use GD&T from a “verification of the requirement” perspective, so learning GD&T from that perspective makes it more useful on the job.

Each workshop participant receives:

• The Fundamentals of GD&T textbook by Alex Krulikowski
• The Ultimate GD&T Pocket Guide (ASME Y14.5-1994)
• The Fundamentals of GD&T for Inspectors Workbook
• Cerficate of completion

Skill level needed
The workshop prerequisites are familiarity with:

• Reading engineering drawings
• Common inspection methods and tools from the four categories of inspection equipment  (i.e. functional  gages, open set-up inspection, CMM basics, calipers, micrometers, height gages, shadowgraph, etc.)

Format: This is an interactive workshop. You will work numerous practice problems and be involved in discussions relating to both interpretation and inspection of GD&T requirements. Topics covered include:

Introduction
Course goals and information

Engineering Drawings and Tolerancing
Understand what inspection is
Engineering drawings, terminology, standards, fundamental rules
Why GD&T is superior to coordinate tolerancing for inspection

Geometric Tolerancing Symbols and Terms
Key terms and how they affect drawing interpretation and inspection
Modifiers and symbols used in geometric tolerancing

Rules and Concepts of GD&T
How to interpret and inspect Rule #1 and Rule #2
The basic dimensions, virtual condition, inner and outer boundary, worst-case boundary, and bonus tolerance and their effects on inspection

Form Controls
How to interpret straightness and circularity and their inspection options
An overview of how to interpret cylindricity and its inspection options

Datums (Planar)
Interpreting and simulating planar datums and datum targets for inspection

Datums (Axis and Centerplane)
Interpreting and simulating feature of size datums (RFS and MMC) for inspection

Orientation Controls
How to interpret perpendicularity, angularity, and parallelism and their inspection options

Tolerance of Position
Position: fundamental concepts, definitions, advantages, implied basic relationships, axis and boundary interpretations and their effects on inspection
Understand how to interpret position RFS and MMC applications and inspection options
Functional gages for tolerance of position MMC applications
How to interpret position special applications and inspection options

Runout Controls
How to interpret circular and total runout and their inspection options

Profile Controls
How to interpret profile of a surface applications and inspections options

Students who attend our workshops walk away with more than knowledge. They gain on-the-job skills because our materials are performance-based, and each workshop approaches the subject from a design perspective.
