metric correct answers which unit uses a zero before decimals?
english correct answers which metric must match decimals
feature correct answers the general term applied to describe a physical portion of a part or object,
such as a surface, slot, tab, pin, keyseat or hole.
tolerance correct answers total amount that a specific dimension is permitted to vary
limits correct answers largest and smallest numerical values that the feature can be.
Maximum Material Condition correct answers where a feature of a size contains the maximum
amount of material within the stated limits.
Least Material Condition correct answers where a feature of a size contains the least amount of
material within the stated limits
allowance correct answers intentional difference between the maximum material limits of mating
parts.
dimension correct answers numerical value indicated on a drawing or in documents to define the
size location or orientation of a feature.
-limit tolerance values displayed as stacked
-a zero does not precede a decimal inch that is less than one
-a specified inch dimension is expressed to the same number of decimal places as its tolerance
-fractional inches can be used, but generally indicate a larger tolerance correct answers basic
rules for displaying inch limit tolerance values correctly
Actual Mating Size correct answers The smallest distance between two parallel planes within
which the actual surface features are contained.
feature of size correct answers refers to any surface or set of parallel surfaces associated with a
size dimension.
controlled radius correct answers when the limits of the radius tolerance zone must be tangent to
the adjacent surface
CR 25.5 correct answers give an example of how a controlled radius dimension is shown on the
drawing
limits of size correct answers the amount of variation in size and geometric form of a feature
control.
, Systeme Internationale or International System correct answers What does SI mean?
parenthesis is used for a reference dimension. correct answers what kind of dimension is placed
in parenthesis?
datum correct answers perfect surfaces, planes, points, axes
I O and Q correct answers which letters should you never use
datum feature symbol correct answers In geometric dimensioning and tolerancing, the datums
are identified with a
datum targets correct answers specify points lines or areas of contact on a part that establish
datums when it is not possible to use a surface.
datum target symbol correct answers a circle with a horizontal line through the center.
feature control frame correct answers divided into compartments containing the geometric
characteristic symbol in the first compartment followed by geometric tolerance.
