Get straight answers, useful tips, and clear explanations on our blog. It’s almost like getting GD&T training for free.
We get a lot of questions from students asking why they would want to use Geometric Dimensioning and Tolerancing (GD&T) over coordinate dimensions. Some believe that using GD&T will result in tighter tolerances and increase a part’s cost. Others believe...
What is GD&T? If you are involved in design or manufacturing, you may be familiar with the term, “GD&T,” or “Geometric Dimensioning and Tolerancing”. Geometric Dimensioning and Tolerancing is a set of rules and GD&T symbols used on a drawing...
Precision tops the list of priorities in CNC machining since being off by a few thousandths is enough to cause serious errors. While no machine yields a 100% accuracy rate, specific approaches have been undertaken to manufacture components efficiently and economically.
We at GD&T Basics are excited to be participating in this year’s 2022 International Manufacturing Technology Show (IMTS) held in Chicago, Illinois, September 12-17, 2022.
A keyed joint is used to ensure orientation or restrict rotational movement between parts, as in the case of joining a shaft with a coupling. We discuss how a keyed joint is made and inspected in this article.
In this article, we outline the basic process for adding GD&T to your drawing using SolidWorks. The accompanying video goes into full detail, walking through the entire process for an example drawing.
