Geometric Dimensioning and Tolerancing (GD&T) Level 1 provides the basis for defining and applying the industry-accepted design/engineering language. Implementation of GD&T will improve communication among designers, manufacturing engineers, and quality control inspectors, resulting in accurate use and interpretation of engineering part drawings. Through examination of the ASME Y14.5M-1994 standard, group exercises, and group discussion, participants will develop the ability to relate drawing requirements to actual part function and inspect parts defined by GD&T. Participants will also be able to determine the most appropriate methods of manufacture and inspection.
This course is intended for anyone beginning a new implementation of GD&T, as well as those seeking to improve their understanding of the language. Key individuals who will benefit from this course include design engineers, inspectors, machinists, drafters, manufacturing engineers, tool and die makers, gage designers and makers, management personnel, and tool designers.
