Most quality technicians have been exposed to and probably use geometric dimensioning and tolerance (GD&T) information in their day-to-day work duties. 

Medical devices can present unique challenges for manufacturers. Consequences for malfunctioning equipment can be dire. Because of this, medical device manufacturers must work hard to ensure that their products never fail.

Today’s manufactured components are more complex than ever, with more parts diversity, more model year changes and tighter tolerances than ever before.

If you’ve ever suffered through a difficult lesson, you were likely not in Gary Griffith’s class. Griffith teaches geometric dimensioning and tolerancing (GD&T), quality audits, measuring and gaging, and other quality-related subjects, and though the technical aspects could make for a dry learning experience, his students say Griffith makes it fun.

Today’s manufacturing industry relies on the use of GD&T definitions, and the ability to verify parts directly to them for first article and production inspection and reporting. Only then do orders ship and the manufacturer gets paid. Price and scheduling are negotiable, quality is not!

A noticeable influx of people and activity fueled the second day of IMTS 2018 at McCormick Place. 

CHICAGO - The third day of IMTS began on the shores of Lake Michigan with the Miles for Manufacturing 5K run/walk to raise money for manufacturing education. 

You hear a lot about Geometric Dimensioning & Tolerancing (GD&T) today, but less about its practical deployment and utilization in the manufacturing and inspection process.

Referees at sporting events can fuel elation or outrage with their calls when it comes to a favorite team, but in truth, these people are needed to provide an impartial interpretation of the rules of the game.

GD&T is the only tool we have with which to manage machine part geometry perfectly. In particular, it’s the only tool we have with which to impose truly functional limits of imperfection on machine part features and actually guarantee assembly and operation prior to drawing release.
