connecting things to things
tolerance
used to give a range for error
why
It is too hard to get the exact measurements consistently without error
types
Bilateral Tolerance
one side has its margin for error
the other side has its own margin for error
Bi: two
Unilateral Tolerance
uni: one
only one side is allowed to have an error
Limit Tolerance
both sides share a margin for error
tolerance=upper limit-lower limit
how to add tolerance into drawings
create the model
create the drawings
double click the dimension
save work
assemble model
joints that we used today
revolute joint
spin in one point
rigid joint
connected pieces cant move
explode the model
animation manual explosion
dont overlap too much
Draw using animation
place the image
save draft
add bubbles
add table
2 more items...
use manual transform
remember the lines
Clearance Fit
allows parts to move
maximum shaft is smaller than minimum hole
Interference Fit
hard to move parts
maximum hole is smaller than minimum shaft
dimensioning
parallel
most of the dimensions are taken from one side
superimposed running
simplified parallel
chain
like parallel but everything is side by side
combined
parallel and chain together
small features
arrows on the outside
multiple features
N*Dimension
radius
R(number)
