Geometric Demensioned and tolerances are used because of ___________________.
Universal mass production of parts
_____________ _____________ limites are given both + and - limits.
Bilateral Tolerance
___________ ___________ limits are given only one way, either upper or lower limit will have a value.
Unilateral Tolerance
What is clearance fit?
When there's always space between mating parts.
What is interference fit?
No space between mating parts. Also called a press fit.
What is transition fit?
Mating parts have both clearance and interference fits.
Which centerlines are the primary centerlines?
The centerlines that are in the center of the view.
Which type of hole needs a depth dimension?
Blind hole
What is block dimensioning?
A page tolerance that is used as a general note not covered by some other tolerancing type.
What are continued/chained dimensions?
Multiple dimensions placed end-to-end
What are baseline dimensions?
Multiple dimensions with offset dimension lines measured from the same location.
What are factors to consider when planning dimensions of mating parts?
The length of time they are to be engaged, speed at which they move, load they support, type of lubricant used, average tempurature they will operate in, humidity level, type of material, lifespan, capabilities of machinists operating the tool, and cost. (Length, speed, load, type, tempurature, humidity, material, lifespan, machinist, and cost)
