Learn about how to interpret the variety of things you get from customers.
- [Instructor] Several simple steps will help you gain…an understanding of the meaning…of Geometric Dimensioning and Tolerancing notation.…A good place to start is by reviewing…the geometric control symbols…and understanding the geometry they control.…Next, understanding the use of datum as reference points…will help with fixturing parts from manufacturing…and verification.…Finally, it is important to understand how to read…feature control frames and interpret modifier symbols.…There are many websites and reference guides…that can serve as useful in-depth resources…for this information.…
When learning how to read…Geometric Dimensioning and Tolerancing symbols,…it can be useful to understand how they differ…from traditional plus/minus tolerancing.…In the simple example shown here,…a 75 millimeter hole is positioned in a plate.…The diameter of the hole can vary between 74 millimeters…and 76 millimeters.…The position of the hole can vary…between 99.5 and 100.5 millimeters in one direction…and 109.5 and 110.5 millimeters in the other direction.…
