Programme overview

Geometric Dimensioning and Tolerancing (GD&T) is the language used in design, manufacturing and quality inspection to communicate information on engineering drawings.

 

The GD&T Fundamentals course takes print reading and tolerances to the next level, and is perfect for companies using prints with tolerances on them. Participants will learn how GD&T is used, interpreted and applied across a part’s life cycle with a specific focus on the needs of the polymers industry.

 

In addition to this 3 days programme, participants will receive online access to market leading GD&T material for 90 days post training to hone their learning and expertise.

 

Please note that this course is also available for in-company delivery. A subsided bespoke programme can be designed to meet your specific GD&T challenges saving your company time and money.  

Who is the course for

This programme is suitable for recent Graduate Engineers, Design Engineers, CAD Drafters, Production Associates, Machinists, Programmers, Tool Engineers & Designers, Quality Technicians, Quality Engineers, Inspection Planners, Gage Designers and Managers.
