Geometric Dimensioning and Tolerancing has extensive use in automotive industries, has been identified as a required skill in the Quality System Requirement section of Automotive Industry Action Group’s (AIAG) new quality standard.
TS16949:2002 “Suppliers who design the activity should be qualified in the skill of Geometric Dimensioning and Tolerancing as appropriate.”
Understand and explain the standard requirements, philosophies, concepts, design and tolerance rules, convention, symbols
Understanding common mistakes and misconception in specifying and verifying GD&T requirements;
Apply GD&T rules, tolerances, symbols, modifiers in part and gage drawings to communicate precisely the part and function design requirements/intents, consistently throughout the product life-cycle;
Who Should Attend
Quality Engineers and Managers
New Product Development Managers
Suppliers Quality Assurance
Benefits of Attending
GD&T can save considerable time, money and resources by having clear, concise and consistent communications throughout the entire product life-cycle cycle processes, by getting every personnel involved from product and process designs, prototyping, production, inspector, gage, and tool making to “read from the same page”. GD&T ensures that there is only one interpretation to any drawing as intended by the designer.
GD&T Facilitates an efficient means to communicate specific datum’s on a part.
It allows the use of round tolerance zones as opposed to square or rectangular tolerance zones are given by limit tolerancing methods for cylindrical features.
GD&T uses functional gages to determine part acceptance, which can in many cases reduce inspection time and reliance on highly skilled inspectors.
GD&T develops multiple sources of supply by providing a complete product definition with a single dimensional interpretation.

Feedback From Past Participants
“This training program has helped to take complete knowledge on manufacturing variations on the design”
“ Now we can design the products better from what we have learned from the training session”
“GD&T should be introduced in all manufacturing companies for better dimensioning and understanding”
“Reading and interpreting an engineering drawing skill has improved”
