ALREADY GRADED A+ (BRAND NEW)
1. What is the primary purpose of Geometric
Dimensioning and Tolerancing (GD&T)?
A. To specify only the size of a part
B. To define the allowable variation in form,
orientation, location, and runout of features
C. To replace all linear dimensions on a drawing
D. To specify the manufacturing process
B
GD&T defines the engineering intent of parts
and assemblies by specifying the allowable
variation for geometry, which includes form,
, orientation, location, and runout, in addition
to size.
2. Which ASME standard is the authoritative
document for GD&T?
A. ASME Y14.1
B. ASME Y14.5
C. ASME B4.1
D. ISO 9001
B
ASME Y14.5 is the standard that establishes
the symbols, rules, definitions, requirements,
defaults, and recommended practices for
stating and interpreting GD&T.
3. What does a basic dimension represent?
A. A dimension with a general tolerance
B. A theoretically exact dimension
C. A dimension that is not critical
D. A reference dimension
B
A basic dimension is a theoretically exact value
that establishes the true profile, position, or
, orientation from which geometric tolerances
are applied. It has no direct tolerance of its
own.
4. How is a basic dimension typically indicated on
a drawing?
A. With a +/- tolerance
B. Enclosed in a rectangular box
C. Underlined
D. With an asterisk
B
The standard specifies that a basic dimension
is drawn enclosed in a rectangular frame.
5. Which of the following is a datum?
A. Any surface of a part
B. A theoretically exact point, axis, line, plane,
or combination thereof derived from a datum
feature
C. A tolerance zone
D. A basic dimension
B
A datum is a theoretically exact entity used as
, a reference for establishing the location or
orientation of a tolerance zone. It is derived
from a physical datum feature.
6. What is the primary function of a datum
reference frame?
A. To define the size of the part
B. To establish a coordinate system for
inspection and manufacturing
C. To specify surface roughness
D. To determine the material type
B
A datum reference frame is a system of three
mutually perpendicular planes that provide a
coordinate system for locating and orienting
part features.
7. A feature control frame is composed of which
of the following elements?
A. A geometric characteristic symbol, a
tolerance value, and datum references
B. Only a tolerance value
C. A basic dimension and a tolerance
