Providing you have a basic understanding of geometric dimensioning and tolerancing fundamentals, this course teaches an introduction to functional gaging design and how to verify part dimensional requirements using functional gages and other measurement methods.

Utilizing the expertise of world-renowned GD&T expert Alex Krulikowski, this course offers an explanation of metrology, the roles of the metrologist and inspector, measurement uncertainty, inspection tools, functional gages, inspection planning and reporting, and simulating datums. Newly acquired learning is reinforced throughout the class with numerous practice problems.

The scope of the workshop does not include measurement systems analysis or sampling strategies. For example, the workshop will discuss how to locate a part for inspection on a CMM, but it will not cover how many parts should be inspected to meet AQL levels.

  • What You Receive
  • Learning Objectives
  • Who Should Attend
  • Topical Outline

Each attendee receives a robust collection of learning resources including:

  • Functional Gaging and Measurement Workshop exercise workbook
  • Class handouts
  • Certificate of completion

Tens of thousands of students have learned GD&T through Alex Krulikowski’s textbooks, self-study courses, computer based training, and online learning center.  Students who attend courses like this one walk away with more than knowledge. They gain on-the-job skills because the learning materials are performance-based.

By attending this class, you will be able to:

  • Describe the functions of inspection in an organization
  • Define what measurement uncertainty is.
  • Explain the basic operating principles, strengths, and weaknesses of the three major categories of inspection tools
  • List the types, uses, and tolerance methods for attribute gages
  • Explain attribute gage design fundamentals
  • Develop a measurement / inspection plan
  • Describe the purpose and content of an inspection report
  • Inspect and report size dimensions
  • Describe the basic concepts of datums related to inspection
  • Understand how to simulate datums for inspection
  • Verify flatness, straightness, circularity, cylindricity, orientation, position, runout, profile of a surface, and profile of a line tolerance requirements

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.
