AE421 Quizzes Part 2

Maximum material condition

which of the following is not a type of fit:

False

(T/F) When creating an assembly, the individual part files do NOT need to be saved and stored in the same folder

hole fit

With respect to tolerances, which of the following is NOT a type of fit?

Fit

What is the term for the range of tightness or looseness between parts?

the total amount a specific dimension can vary

Which of the following is the definition of tolerance?

through curves

which tool in NX allows you to create sheet body between two or more curves?

allowance

the minimum clearance space or maximum interference is called what?

dimensions are referenced to each other rather than a common baseline, thus their tolerances are additive

what is tolerance stacking?

whether the specified tolerance will allow mating parts to fit together, the manufacturing technique, the resulting cost of the part

which of the following items are things that should be considered when specifying a tolerance

extrude, revolve, & thicken

you can rename individual part files after they have been added to an assembly without it affecting the assembly

revolve

tolerance

when designing and dimensioning a part that will be manufactured, the definition of _____ is “the total amount a specific dimension can vary”

power basis form

which of the following parametric curves is normally NOT used in CAD software?
