3 Benefits of Using GD&T in CNC Machining

What is Geometric Dimensioning and Tolerancing?

Geometric Dimensioning and Tolerancing, abbreviated as GD&T, is a system for defining and communicating design intent and engineering tolerances in manufacturing. GD&T is a language of symbols and standards that describes any part dimensions and its allowable variation in size, form, orientation, and location.

Why Use GD&T in Complex CNC Machining?

There are 3 benefits of using GD&T in complex CNC machining.

1. Enhanced Communication: 

GD&T allows you to convey substantial information about your part’s design using a relatively small amount of letters, numbers, and symbols. The use of a single and standardized GD&T language ensures engineering, design, production, and quality teams are able to communicate clearly and accurately with each other, saving time and increasing efficiency.

2. Accurate Production:

Since GD&T is such a precisely articulated system of language, it minimizes ambiguity in the description of a part’s design. Part production becomes more repeatable and consistent – simplifying inspection, reducing the part rejection rate, and improving quality. 

3. Increased Flexibility: 

GD&T specifies the design intent instead of the specific geometry, providing the appropriate tolerances that maximize production. It results in more manufacturing flexibility and larger tolerances, especially for intricate or complex designs!
