What are the three categories of dimensioning mentioned in the text?
- Geometric dimensioning, general dimensioning, and surface texture (correct)
- General dimensioning, tolerancing dimensioning, and surface roughness dimensioning
- General dimensioning, specific dimensioning, and surface dimensioning
- Dimensioning by function, geometric dimensioning, and surface roughness dimensioning
What is the purpose of Geometric Dimensioning & Tolerancing (GD&T)?
What is the purpose of Geometric Dimensioning & Tolerancing (GD&T)?
- To define features more accurately without increasing tolerances (correct)
- To simplify the drawing process by reducing the number of dimensions required
- To increase tolerances without affecting the accuracy of features
- To provide a more generalized approach to dimensioning and tolerancing
Why has GD&T increased in practice in the last 15 years according to the text?
Why has GD&T increased in practice in the last 15 years according to the text?
- Due to the introduction of ISO 9000 standards (correct)
- To simplify the process of dimensioning and tolerancing
- To reduce the cost of manufacturing
- Because of the introduction of advanced measurement tools

Geometric Dimensioning and Tolerancing (GD&T) is a means of dimensioning and tolerancing that considers the function of the part and its function with related parts.

ISO 9000 requires not only the requirement of something, but also how it is to be controlled, leading to an increase in the practice of GD&T in the last 15 years.

The Envelope Principle in GD&T allows a variation in form between the least material condition (LMC) and the maximum material condition (MMC) of mating parts.
The Envelope Principle in GD&T allows a variation in form between the least material condition (LMC) and the maximum material condition (MMC) of mating parts.
The Maximum Material Condition (MMC) refers to the condition where a size feature contains the maximum amount of material within the stated limits of size.
