Geometrical Dimensioning and Tolerancing
Geometrical Dimensioning and Tolerancing (GDT) is an international standard that uses symbols that precisely communicate the design intention of a part to the people making it.
This language is mathematical in nature and requires a unique set of knowledge and skills to interpret and apply in the workplace.
In today’s world of global mass production, parts in an assembly are most likely not even being made in the same country, much less by the same person. Without GDT to communicate the designer’s intent of the part, we cannot be confident it will be made and inspected correctly.
This means GDT must be the native language for the next generation of engineers, machinists, and programmers. So how do we ensure GDT is a native part of our manufacturing language? Rather than teaching it secondarily, after learning limit dimension and all its flaws, we need to include it in the entire learning process, and we do this through an approach called “weaving.”
Weaving is a wax on wax off process that embeds GDT across all lines of communication without formal coursework. In the movie The Karate Kid, sensei Miyagi and his student Daniel strike a deal: “I will teach you karate. You will do what I say.” But instead of teaching and mastering one move at a time like they do in a traditional dojo, Mr. Miyagi teaches Daniel karate through everyday tasks - cleaning cars, painting the fence … Wax on. Wax off.
This changes your culture of learning and empowers your organization to master the utility of GDT. Our GDT training will show your team how to find those natural opportunities within your training to make GDT your 1st language.
Training topics include:
- Introduction to Weaving
- 1st vs 2nd Language Exercise
- How GDT Works
- Things to Remember about GDT
- Development Exercises
