Who is GD&T Training for?
Anybody who makes or uses engineering drawings should know GD&T. This includes, drafters, designers, engineers of all disciplines, buyers, machinists, maintenance technicians, salespeople, auditors, inspectors, and their management. In our course, Texas students learn:
GD&T Training Course Overview:
Prints serve their internal customer users including Product Design, Purchasing, Manufacturing Engineering, and Production. It is important that information be communicated clearly and in a useful manner to these important stakeholders. As such, geometric dimensioning and tolerancing (GD&T) symbology is articulated in ASME Y14.5 to satisfy this need.
Our 2-day introduction to GD&T fundamentals covers the following with exercises throughout and a test for comprehension at the end. Texas students will learn:
|Overview. Units of measure, fundamental dimensioning rules, terms, material conditions, extreme form variation, allowance, clearance, and types of fit.|
|Symbols. Dimensioning symbols and templates, datum features and targets, geometric characters, material conditions, and feature control.|
|Datums. Symbol, surface, frame, and target. Also includes partial and coplanar.|
|Material Conditions. Limits of size, perfect form boundary, regardless of feature size (RFS), maximum material condition (MMC), least material condition (LMC), datum feature hierarchy, and datum precedence.|
|Form and Profile. Straightness, flatness, circularity, cylindricity, profile, and, free state variation.|
|Orientation and Runout. Orientation, runout, combinations, tangent plane.|
|Location. Position, coaxial features, non-parallel holes, slotted holes, spheres, fasteners, projected zones, virtual conditions, concentricity, coaxiality, and symmetry.|
