sketches and tolerances Flashcards
what is the tolerance on 1.5 inches giver or take .003 thou?
.006
this type of fit for a shaft if the shaft is 1.875 and the hub diameter is 1.870
interference fit because the shaft is bigger then the hub
Calculate the maximum limits for a size of 1.875 to .010 thou.
1.875=.010=1.885
a center line is shown as
long and short dashes
engineering orthographic projections
first and third angle
this lines indicted visible lines of the
object lines/ IP
Lines that show the surfaces of features in chosen views are
hidden lines
lines that are used to shorten the views of intersections are
break lines
parrell diagonal lines with hatch marks are identifed in a drawing as
sectional lines
lines that move object lines out to convienance space
extension lines
lines that indicated the distance between extension lines and arrow heads are
dimension lines
a line in uni directional refer to methods of ?
dimensioning and object
two types of dimensions used in technical drawings over all dimension and detail dimensions
True
Bores on techincal drawings are
shown with leader lines
a view which shows aspect of n object of top and side views
sectional
the view that shows the viewer section of the shape and material
removed sectional view
a view which separates a common axis and shows exactly how a group of parts fits together
exploded view
tolerance measurement that indicated rotating shaft that deviates from center is called
run out
tolerance in surface texture is measures in
micro meters
the part of a technical drawing that contains information such as title scale and number
title block
the purpose of a revision block is to what
show what’s been revised (revision)
a list on the drawing that indicates the size and number of parts required is
Item or materials list
given the scale 1-10 what is the actual length, of the part be 25mm
250 mm
on a scale of 1-20 what is the bore radius is 25 so diameter 50x20
1000
a drawing that does electrical drawings shit
schematic drawing
top view of orthpathic drawing
plan view
