3. Trailing zeroes


◉ From the textbook 15.03...
T/F: Each dimension shall have a tolerance. Answer: True.


◉ From the textbook 15.03...
T/F: Dimensioning and tolerancing shall be complete so there is a
full understanding of the characteristics of most features. Answer:
False, there must be full understanding of all features. No ambiguity.

,◉ From the textbook 15.03...
T/F: Each necessary dimension of an end product shall be shown, no
more dimensions than those necessary for complete definition shall
be given. Answer: True.


◉ From the textbook 15.03...
T/F: The drawing should define a part, as well as specifying
manufacturing methods. Answer: False, manufacturing methods are
not to be specified in engineering drawings.


◉ From the textbook 15.03...
T/F: Dimensions should be shown in true profile views, and refer to
visible outlines in an arrangement that provides information for
optimum readability. Answer: True.


◉ From the textbook 15.04...
Define dimension. Answer: A numerical value expressed in
appropriate units of measure and used to define the size, location,
geometric characteristic, or surface texture of a party or part feature.


◉ From the textbook 15.04...
Define arrowhead. Answer: A small triangle at the end of dimension
line and leaders to indicate the direction and extent of a dimension.

,◉ From the textbook 15.04...
Define dimension line. Answer: A thin, dark, solid line that
terminates at each end with arrowheads. The value of a dimension is
typically shown in the center of the dimension line.


◉ From the textbook 15.04...
Define extension line. Answer: A thin, dark, solid line extending from
a point on an object perpendicular to a dimension line. Used to
indicate the extension of a surface or point to a location preferably
outside the part outline.


◉ From the textbook 15.04...
Define leader. Answer: A thin, dark, solid line terminating with an
arrowhead at one end and a dimension, note or symbol at the other.
Used to direct a dimension , note or symbol to the intended place on
the drawing.


◉ From the textbook 15.05...
What is the contour rule? (contour dimensioning) Answer: - Each
dimension should be placed in the view where the contour shape is
best shown.
- Dimension only to solid lines.

, ◉ From the textbook 15.05...
Dimensions that help to define outer boundaries of parts quickly.
Answer: Overall dimensions.


◉ From the textbook 15.05...
Dimensions identified by numbers enclosed within parentheses.
Answer: Reference dimensions.


◉ From the textbook 15.06...
Circles are typically dimensioned as, _____ and arcs are typically
dimensioned as, _______. Answer: Diameters, Radii.


◉ From the textbook 15.06...
What kind of dimensioning?
- All dimensions in a given direction originate from a base or datum.
- Frequently used for CNC machines that work from a rectangular
coordinate system. Answer: Baseline dimensioning.


◉ From the textbook 15.06...
What kind of dimensioning?
- Features are dimensioned relative to one another.
- It can cause problems with tolerance accumulation, normally not
preferred. Answer: Chain dimensioning.
