Total runout (runout tolerance)[two arrows] - ANSWER3D control for rotating parts
relative to a datum axis. (cylindrical surface = controls circularity, straightness, taper,
concentricity, and surface profile; flat surface = controls wobble, perpendicularity,
and flatness)
Basic dimensions (those with a box around them)... - ANSWERare theoretically exact
and locate the perfect position of features from clearly identified datums
The feature control frame - ANSWERcontains the geometric characteristic symbol,
the geometric tolerance, and the relative datums
Free running fit - ANSWERnot for use where accuracy is essential, but are good for
large temperature variations, high running speeds, and heavy journal pressures
A dimension is expressed to the same number of inches of decimal places as its
________. Zeros are added to the _____ of the decimal point where necessary -
ANSWERtolerance; right
ASME stands for - ANSWERAmerican Society of Mechanical Engineers
Most drawings conform to the ______ system or they conform to the ____ system -
ANSWERSI; U.S. Customary
Where the dimension is less than one millimeter... - ANSWERa zero precedes the
decimal point
Where the dimension is a whole millimeter... - ANSWERneither the decimal point nor
the zero is shown
Where the dimension exceeds a whole number by a decimal fraction of one
millimeter... - ANSWERthe last digit to the right of the decimal point is not followed
by a zero
T/F commas and spaces shall be used to separate digits into groups in specifying
millimeter dimensions on drawings - ANSWERfalse
T/F A zero is not used before the decimal point for values less than one inch -
ANSWERtrue
contour rule or contour dimensioning - ANSWEReach dimension should be placed in
the view where the contour shape is best shown
, T/F Dimensions should appear multiple times in different views on a drawing -
ANSWERfalse, they should only apper once
Dimensioning and tolerancing shall be complete so that... - ANSWERthere is full
understanding of the characteristic of each feature
circles are typically dimensioned as - ANSWERdiameters
arcs are dimensioned as - ANSWERradii
T/F you should give dimensions between holes vs dimensioning the holes from the
end of the part - ANSWERTrue
Baseline Dimensioning - ANSWERall of the dimensions in a given direction originate
from a base or datum (frequently used for CNC machines)
Chain Dimensioning - ANSWERfeatures are dimensioned relative to one another
(used when a part function requires that features be related to one another)
T/F chain dimensioning is often preferred over baseline - ANSWERFalse, Baseline
dimensioning is prefrred
Chain dimensioning usually yields the _______ accumulation of tolerance between
features,where the maximum distance between features is... - ANSWERlargest;
equal to the sum of the intermediate distances
dimension only to _______ or _______ lines - ANSWERvisible; solid
Dimension lines also should be at least _____ ___ from any view, helping to avoid
clutter. - ANSWER10 mm
When dimensions are placed outside other dimensions, there should be at least ___
___ between dimension lines - ANSWER6 mm
When dimensioning a visible gap of at least ___ ___ should be between extension
lines and object geometry - ANSWER1 mm
when dimensioning, extension lines should extend ___-___ ___ past their
corresponding dimension line - ANSWER2-3 mm
Chamfersy are dimensioned by - ANSWERgiving a length from the end of the part
and an angle or by specifying two distances
|___| represents what on a drawing? - ANSWERcounterbore
\/ represents what on a drawing? - ANSWERcountersink
