Geometric Dimensioning and Tolerancing

Description:

This extensive workshop is designed to impart functional knowledge of Geometric Dimensioning and Tolerancing to those good at Blue Print Reading. The workshop is conducted using a blend of lecture / discussion, quizzes, and hands on experiments for experiential learning; this approach ensures the concepts are well understood and retained for long time to come. Myths of GD&T are also exposed, enabling the true value of this subject to be appreciated and understood. Plenty of actual products / parts are discussed in class to clarify application of the 1994 ASME standard. Participants are encouraged to bring in drawings from their companies for class discussion.

Benefits:

Eliminate / reduce print caused problems with regard to components / assemblies

Cut costs from false accepts / rejects

Improve product quality

Topics Covered:

Coordinate tolerancing vs GD&T

Symbols, terms, rules, and concepts

Controls – form, orientation, profile, run out, concentricity, symmetry

Datums – planar and axial

Tolerance of position

Tolerance stackup analysis (Introduction only)

Pre-requisites:                  Good to excellent knowledge and experience with Blue Prints
