Question

Which statement best describes what the ASME-Y14.5M-2009 covers? a) Dimensioning and tolerancing standards for drafting and gaging of rigid mechanical parts. b) A symbolic means of dimension^ and tolerancing. c) Dmiensioning and tolerancing standard with respect to how parts are manufactured. d) Establishes uniform practices for stating and interpreting dimensiomci, tolerancing, and related requirements for use on engineering drawings and related documents. 2. Using GD&T;: a) Tighter tolerances can be achieved in manufacturing. b) Creates a means for expressing the true design requirements for a part. c) More tolerance is made available to manufacturing than is possible with only plus/minus tolerancing d) Both b) and c) 3. What is a Basic Dimension? a) An exact dimension with no tolerance associated with it. b) A dimension in a box that must be strictly adhered to by manufacturing c) The nominal size of a feature. d) A numerical value that describes a theoretically exact size, profile, orientation or location of a feature or a datum target. It is the basis from which permissible variations (tolerances) are established. 4. What is a Feature Control Frame? a) A symbolic means of expressing the type of control on a feature, and defining a tolerance zone for that control. b) A box on the drawing that tells the manufacturer how to make the part. c) A box on the drawing that tells the inspector what measurements have to be made for every part. d) A symbol that dictates the tolerance of position for a datum target. 5. What is a "Material Condition Modifier?" a) The maximum dimension possible according to the tolerance specified. b) The minimum dimension possible according to the tolerance specified. c) A symbol placed on a feature of size that states how much tolerance is available for that feature. d) A symbol (or lack thereof) placed in a feature control frame that indicates how much, or if, any extra geometric tolerance is available for the feature as the actual mating size of the feature changes.

Explanation / Answer

The Y14.5 standard is considered the authoritative guideline for the design language of geometric dimensioning and tolerancing (GD&T.) It establishes uniform practices for stating and interpreting GD&T and related requirements for use on engineering drawings and in related documents.

2.Both B and C

3. Basic dimensions are defined as a numerical value used to describe the theoretically exact size, profile, orientation or location of a feature or datum target.

4. a)

5. d)
