This program provides insight into the widely used, little understood, but highly practical and
productive concept of "Geometric Dimensioning & Tolerancing" and how it actually defines
the function and relationship of mating part features.

This 2 day program discusses how the concept allows for much better communication between
design, manufacturing and inspection and provides for common understanding and
interpretation between customer and supplier. Also studied is the economics of the use of
"Geometric Dimensioning & Tolerancing" and the resulting use of functional gaging.

           Curriculum

	Introduction Gaging & measuring principles Units of measurement - decimal inch
	Geometric Tolerancing Points, lines and surfaces Feature control frame - application to drawings & surfaces
	Datums & the 3-Plane Concept Datum for geometric tolerancing 3-plane concept - primary secondary & tertiary Datum feature symbol Association with geometric tolerances Multiple datum features
	Datum Target Symbol Identification of targets
	Datum Features Subject to Size Variations RFS and MMC applications - datum features
	Orientation Tolerancing for Features of Size Perpendicularity and parallelism tolerance Control on a MMC basis Internal and External cylindrical features Specifying parallelism for an axis Perpendicularity for a median plane or an axis
	Basic Gaging Principles for Orientation Tolerancing Measuring principles -- when MMC is and is NOT specified
	Positional Tolerancing Material condition basis Positional tolerancing for circular features -- (MMC; RFS; LMC)
	Positional Tolerancing for Noncylindrical Features Noncircular features at MMC & RFS
	Flatness & Straightness
	Circularity (Roundness) & Cylindricity Tolerance Errors of circularity Circularity tolerance Circularity of noncylindrical parts Assessing circularity
	Profile Tolerances
