Geometric Dimensioning and Tolerancing (GD&T) - North

About Course:

Geometric Dimensioning and Tolerancing (GD&T) is an international language used on engineering drawings.

Classes will include... Introduction; Dimensioning and Tolerancing Fundamentals; Symbols, Terms, and Rules; Datums; Form controls – Flatness, Straightness, Circularity, Cylindricity, Free state variation; Orientation – Parallelism, Perpendicularity, Angularity; Position, General – Specifying the position tolerance, Regardless of feature size, Maximum material condition, Shift tolerance, Boundary conditions, “0” Positional Tolerancing; Position, Location – Fasteners, Projected Tolerance Zones, Multiple patterns of features, Composite positional tolerancing, Two single-segment feature control frames, Nonparallel holes, Counterbored holes, Noncircular features, Symmetrical features; Position, Coaxiality; Concentricity and Symmetry; Runout; Profile.

Course Outcome:

• Providing uniformity in drawing specifications and interpretation, and geometric tolerancing to reduce controversy, guesswork, and assumptions throughout the manufacturing and inspection process.
• When GD&T is used properly it will improve communication and result in better product design. Proper use of GD&T also increases product tolerances, saving your organization time and money.
