GD&T is a system for defining and communicating engineering tolerances. This is conducted by using symbolic language from engineering drawings, which describe the nominal (theoretically perfect) geometry of controlled features. This language also communicates allowable variation in size, geometrical characteristics, and variation between features.
The Advanced GD&T course focuses on the fundamental understanding of the 14 tolerances. Practical aspects of different call-outs are discussed with the opportunity for hands-on application.
Interested in Advanced GD&T?
Intermediate Inspection Workshop is a five-day program designed to help train Pratt and Whitney employees and suppliers on how to properly measure and evaluate measurement systems. Students will partake in hands-on workshops and projects to prepare for real-world application.
This certificate program will cover the foundational skills required to understand properly utilizing common measurement instruments used on aerospace engine components.
Interested in our Intermediate Inspection Workshop?
Earn a Certificate in Manufacturing Metrology through the College of Engineering, Technology, and Architecture (CETA). Courses run concurrently, and you have the potential to complete the certificate in one year.
