Detailed Rationales
, Blueprint Reading & GD&T; (Geometric Dimensioning and
Tolerancing)
Question 1.
On a print, a dimension shown as Ø0.500 ±.002 with a feature control frame containing a position
symbol and a value of Ø.010 at MMC is calling out:
A. A size tolerance only, with no location control
B. A positional tolerance that may grow when the feature departs from MMC (bonus tolerance)
C. A profile tolerance applied to the whole part
D. A runout tolerance relative to a datum axis
Question 2.
In GD&T;, what is the primary purpose of a datum reference frame (DRF)?
A. To specify surface finish requirements
B. To establish an immovable, mutually perpendicular 3-plane coordinate system for locating and
orienting features
C. To define the material condition of a feature
D. To indicate the direction of a chamfer
Question 3.
A section view on a die component print is used primarily to:
A. Show the part rotated 45 degrees for aesthetics
B. Reveal interior detail and features that are hidden in a standard orthographic view
C. Replace the need for a title block
D. Indicate the heat treatment specification
Question 4.
Which line type on a mechanical print represents a centerline?
A. A thick continuous line
B. A series of long dashes
C. Alternating long and short dashes
D. A thin line with arrowheads at both ends
Question 5.
A flatness callout of 0.001 applied to a die shoe's mounting surface controls:
A. The size of the die shoe
B. How parallel the top and bottom surfaces are to each other
C. The amount the surface may deviate from a perfect plane, independent of size or location
D. The angular orientation to a datum
, Question 6.
What does the symbol ■ (a circle with a diagonal slash) represent in a feature control frame?
A. Maximum material condition
B. Diameter
C. Least material condition
D. Free state
Question 7.
On a stamping die detail print, a note reading "BREAK ALL SHARP EDGES .005-.010" instructs the
tool maker to:
A. Grind a full radius on every edge equal to .010
B. Apply a light deburr/chamfer within the stated range on edges not otherwise dimensioned
C. Leave all edges as machined with no deburring
D. Heat treat the edges to reduce sharpness
Question 8.
True position tolerancing compared to coordinate (plus/minus) tolerancing for hole location generally
results in:
A. A smaller, more restrictive tolerance zone
B. A cylindrical tolerance zone that is often larger and functionally more accurate than a square zone
from coordinate tolerancing
C. No difference in the tolerance zone shape
D. Elimination of the need for datums
Question 9.
A datum feature symbol on a print is typically shown as:
A. A hexagon with an X inside
B. A capital letter enclosed in a square or a rectangle attached to a leader with a filled or unfilled
triangle
C. A wavy line under the dimension
D. A double arrow pointing to the surface
Question 10.
When a print specifies a tolerance of ±.0005 in. on a punch diameter, which measuring instrument is
most appropriate to verify it?
A. A steel rule
B. A dial caliper reading to .001
C. A micrometer or comparator capable of resolving to .0001 in., properly calibrated and
temperature-stabilized
D. A tape measure
