Geometric Dimensioning & Tolerancing (GD&T)

This instructor-led course simplifies GD&T learning, using mostly visual material, to explain basics of GD&T application, interpretation and verification as well as implications from design to manufacturing.  Exercises are used throughout the course.  Students learn faster and retain more information with visuals and 3D objects.

OVERVIEW
The impact and importance of industry standards
Review of drawing standards and notes in practice
Coordinate tolerances and geometric dimensions
What is a tolerance zone

FUNDAMENTALS
GD&T symbols and their changes over time
GD&T rules
GD&T in manufacturing and inspection

PART FORM CONSIDERATIONS
Straightness, Flatness, Circularity and Cylindricity tolerances

DATUMS, THEIR USE AND IMPLICATIONS
Datum systems and key factors
Datum targets
Datum referencing and simulation
Implications of material condition modifiers

PART ORIENTATION
Parallelism, Perpendicularity and Angularity tolerances

POSITION
Position tolerance concepts and use
Understanding use of material condition modifiers
Position tolerance calculations
Concentricity versus position

RUNOUT, CONCENTRICITY
Circular and total runout tolerances

PROFILE
Profile tolerance concepts and applications
Profile tolerance measurement

Anyone interested in developing their career with GD & T.  Participants should understand how to read basic prints/drawings used in manufacturing before taking this class.

Rich was very knowledgeable and had a genuine interest in if the students understood the info he presented.

An amazing teacher! Every topic had its amount of time and he explained and answered all our questions. Everything he covered, I do in my job, everything went well!

Rich made course easy to learn with a very fair pace.

Materials were useful. Used Props – not just powerpoints.

Good teaching, well done!
