Term
In stacks that go left and right, which direction is positive? 

Definition


Term
In stacks that go up and down (radial stacks), which direction is positive? 

Definition


Term
What is another term for stacks that go up and down? 

Definition


Term
What are the basic steps that make up the process of tolerance analysis? 

Definition
 Identify what requirement is under test
 Identify all dimensions that contribute to the gap
 Assign each dimension a positive or negative value
 Decide which routes will be factors in the analysis
 Decide which tolerances will be the biggest factors
 Add all positive and negative dimensions to calculate mean gap
 Add the sum of the equal bilateral tolerances to the mean gap to determine maximum gap
 Subtract the sum of the equal bilateral tolerances from the mean gap to determine minimum gap



Term
True or false: Correct routes give the largest min gap and the smallest max gap. 

Definition


Term
True or false: never take the shortest route 

Definition
False, always take the shortest route 


Term
True or false: tolerance analysis methods change depending on the type of tolerance on a dimension (equal, unequal, unilateral) 

Definition
False, the methods are the same 


Term
What is the meaning of a virtual condition? 

Definition
An inner or outer tolerance boundary that remains constant. 


Term
What is the meaning of a resultant condition? 

Definition
The "worst case" of a nonconstant inner or outer tolerance boundary 


Term
What is the virtual condition of the shaft?

Definition


Term
What is the resultant condition of the shaft?
[image] 

Definition


Term
True or false: resultant conditions are generated on the opposite side of virtual conditions 

Definition


Term
Why are resultant and virtual conditions important in tolerance analysis? 

Definition
They are used to create equal bilateral tolerances from feature control frames that use MMC and LMC. 


Term
What is a factor that can ruin virtual or resultant condition calculations? 

Definition
If the derived median line of the feature is not straight 


Term
What are the steps to convert an unequal tolerance to a equal tolerance? 

Definition
 Find the upper tolerance limit
 Find the lower tolerance limit
 Add the two values and divide by two to get the mean
 Subtract the lower tolerance limit from the upper tolerance limit
 Divide by to to get the ± tolerance



Term
What tolerance is placed on basic dimensions? 

Definition
Zero. Instead, tolerances affect the features themselves by calculating the virtual and resultant conditions.
