Geometric Dimensioning and Tolerancing Quiz ASME Y14.5 – 2009

So you think you know Geometric Dimensioning and Tolerancing (GD&T)?

Take our real-time interactive quiz. You’ll receive your score immediately after completing the quiz.

This test is for the evaluation of knowledge and skills in Geometric Dimensioning & Tolerancing per the ASME Y14.5 -2009 standard.

Welcome to your GDT Quiz - Advanced

Which statement best describes what the ASME-Y14.5 - 2009 covers?

Refer to Figure 1 for the following questions:

Using GD&T:
How can properly implemented GD&T save money in the manufacturing process?
What is a Basic Dimension?
What is a Feature Control Frame?

Select the description for each Geometric Characteristic Symbol:

With the same actual datum feature sizes and considered hole size defined in the previous question, how much extra tolerance does the 4-hole pattern have relative to the "center of the part?" (Datum features "B" and "C" define the "Center" of the part.)

The use of zero positional tolerance at MMC:
The use of the term, “BOUNDARY” under a position feature control frame:
A projected tolerance zone:

Refer to Figure 4 for the following questions:

Using Figure 4, how flat must the considered surfaces be (worst case) to meet the print requirements?
In Figure 4, if the actual of the overall height (when measuring the part against the 50mm specification) was 50.15, would that part be within the print specifications?
