This is a brief article on geometric dimensioning and tolerance and are also known as GD&T and what i want to cover in this article is some of the basics of: Why you want to use GD&T, What some of the benefits are and how you utilize GTD to set up a particular part so you can go through the manufacturing and inspection process ?
Why do you use GD&T?
There are
three basic reasons our three basic elements of GD&T. One it
helps communicate part intent and function through the design
manufacturing and inspection that means when you're designing the component
or when you're manufacturing the components or when you're
inspecting component, you're able to do is see how the part is put
together and understand what the relevancy of the features are in
relationship to each other.
Hold on! A very informative article - Geometric Dimension and Tolerance - Online Training
It also helps you to do
a standard with how you set the part up when you manufacture it as well as when
you inspect. It also provides a more precise depiction of part features.
So, what this GD&T
will do is? it'll help you understand how certain features in your
component are actually going to be precisely measured with relationship
to their use and third it focuses on feature to feature
relationships.
GD&T the components
of GD&T actually help you understand how one feature interacts with another
feature you know and what is the most important aspect of that feature
are the most important series of aspects of that feature that help you
with that relationship to other features.
So it helps you get
a better understanding of what GD&T is and it helps you
understand you'll develop an inspection method and a manufacturing
method that is consistent so nobody's just winging it everybody's
doing everything the same way and you end up knowing different part
is good or bad or manufactured poorly because everybody follows the
same standard method.
Benefit of taking GD&T Training course
GD&T is essential to
ensure functional information and design intent from the assembly to its
individual parts. This insures accurate fitting assemblies and spare
parts regardless of where they are manufactured.
Designers, toolmakers,
inspectors and project managers will greatly benefit from GD&T knowledge.
Geometric Dimensioning and Tolerancing course
here by GD&T Online covers the fundamentals and principles of the ASME
Y14.5-2018 GD&T standard. Most courses focuses on the geometric
characteristic symbols explaining in detail each symbol, feature control
frames, different modifiers and how they affect tolerancing when placed in the
feature control frame.
The course also goes into depth on datums and datum reference frames, partial datums and datum target points. You will be exposed to methods of inspection for the characteristics symbols, composite feature control frames and design exercises. The course is delivered with a combination of principles, exercises and drawing examples from an instructor with professional ASME standing and over 20 years of practical experience.
