PART A – TRUE / FALSE
1. One purpose of dimensions and tolerances is to define the manufacturing
setup.
Answer: False
2. Relationships between part surfaces should be defined based on their
function in the product.
Answer: True
3. The nominal size of a dimension is always the mean of the tolerance values.
Answer: False
4. Under ASME Y14.5, all dimensional limits are absolute.
Answer: True
5. A single feature control frame is required to have five or more compartments.
Answer: False
6. Basic dimensions are usually specified by enclosing the dimension in a
rectangle.
Answer: True
7. The sequence of listing notes indicates the importance of notes (1 is more
important than 4).
Answer: False
8. Using CAD models rather than an engineering drawing will eliminate most
sources of variation.
Answer: False
9. Dimensions are used to define size, location, orientation, and filtering of a part
feature or feature of size.
Answer: False
10. The two common linear units of measure are the decimal inch and the meter.
Answer: False
11. Coordinate tolerancing refers to tolerances verified with a coordinate
measuring machine (CMM).
Answer: False
12. There are four major shortcomings of using coordinate tolerancing.
Answer: True
13. An undefined measurement setup is one of the major shortcomings of
coordinate tolerancing.
Answer: True
14. Part acceptance disputes are one consequence of coordinate tolerancing.
Answer: True
15. The design philosophy of GD&T is to assign tolerances so that manufacturing
is economical.
Answer: True
16. One benefit of GD&T is that it improves communication.
Answer: True
17. GD&T eliminates the problem of tolerance accumulation through the use of
basic dimensions.
Answer: True
18. There are three major components of GD&T.
Answer: True
19. Geometric tolerances should be used whenever you want to increase
manufacturing costs.
Answer: False
