ANSWERS BRAND NEW EXAM ALREADY GRADED A+ PASS
Total runout (runout tolerance)[two arrows] Ans✓✓✓3D 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)... Ans✓✓✓are
theoretically exact and locate the perfect position of features from
clearly identified datums
The feature control frame Ans✓✓✓contains the geometric
characteristic symbol, the geometric tolerance, and the relative datums
Free running fit Ans✓✓✓not 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 Ans✓✓✓tolerance; right
ASME stands for Ans✓✓✓American Society of Mechanical Engineers
,Most drawings conform to the ______ system or they conform to the
____ system Ans✓✓✓SI; U.S. Customary
Where the dimension is less than one millimeter... Ans✓✓✓a zero
precedes the decimal point
Where the dimension is a whole millimeter... Ans✓✓✓neither the
decimal point nor the zero is shown
Where the dimension exceeds a whole number by a decimal fraction of
one millimeter... Ans✓✓✓the 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 Ans✓✓✓false
T/F A zero is not used before the decimal point for values less than one
inch Ans✓✓✓true
contour rule or contour dimensioning Ans✓✓✓each 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 Ans✓✓✓false, they should only apper once
, Dimensioning and tolerancing shall be complete so that...
Ans✓✓✓there is full understanding of the characteristic of each feature
circles are typically dimensioned as Ans✓✓✓diameters
arcs are dimensioned as Ans✓✓✓radii
T/F you should give dimensions between holes vs dimensioning the
holes from the end of the part Ans✓✓✓True
Baseline Dimensioning Ans✓✓✓all of the dimensions in a given
direction originate from a base or datum (frequently used for CNC
machines)
Chain Dimensioning Ans✓✓✓features 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 Ans✓✓✓False,
Baseline dimensioning is prefrred
Chain dimensioning usually yields the _______ accumulation of
tolerance between features,where the maximum distance between
features is... Ans✓✓✓largest; equal to the sum of the intermediate
distances
