Geometric Dimensioning and Tolerancing Training: Level Two

Course Description

A three day training course intended for anyone who needs to understand the theory and practice of ASME Y14.5 – 2018 Geometric Dimensioning & Tolerancing (GD&T).   Students should have some knowledge of interpreting technical drawings or inspection experience.  Class will alternate between a power point presentation, class discussion and practice exercises. Question and answer sessions will take place during the course to ensure knowledge and understanding.  Practical examples and workbook exercises provide practice in interpreting and analyzing GD&T.

Aims & Objectives
