help quotation in inches

[salvatorev]

Hi, I'm new and I don't know if this is the right section. However I wondered if someone could help me to interpret this quotation (in inches), I don't understand the acronym r and tell what they refer to (think of the radius and the diameter) the problem is that adding is not that 7 (written in the center)
thanks to the help

 

[MassiVonWeizen]

It is not a 7, but a notch (what I have no idea) like the one on the lower right. In addition, the size of the text would be disproportionate to other quotas

are the signs of processing.
look that there are others, on the opposite face, on the three sides of the 3/4 quarry, on the plane from which the two 3/4 pins come out and on the cylindrical surface of the two pins themselves.

Bye.

Hi.
but the signs of processing
for inch drawings
should not be the key to violin
Thank you very much

I don't know.
I know instead that the tip of the working sign must point on the processed surface and in this example it is not so everywhere.

and should also be placed on the side to work, while the two on the bottom right on the pocket are on the opposite side to how it should be. Am I wrong?

 

[SHIREN]

it is very likely that the sign of processing on the half-axis
to indicate that the two sides of the 45° bushing are worked and symmetrical
compared to the axis
as well as 15°
I add
is a collar that is obtained by cast iron fusion (ice)
therefore there are crude areas
Perhaps it would be better if you indicated a tolerance than the axis
and a tolerance of the angle at 90° and 30°
Thank you very much

about the quarry I can't understand if the part between the two curved parts is perpendicular or is radial in the sense that it is directed in the direction of the ''centro'' of the circumference that is used to trace those curved parts

 

[Fulvio Romano]

What are the "working marks"?
Aren't those symbols of roughness?
in this design all "white" surfaces are not melt raw, so they must be worked with that roughness, and are indicated with this symbol.

true, but this design is not normal. seems to be a drawing exercise, whose solution is to produce a table in accordance, so the "text" of the exercise must be as far as possible out of order not to pilot the solution.
I have often found these types of drawing filled with, not really mistakes, more than other inaccuracies, but are made especially so.

Sorry I can't decipher the part between the two sides
You could make an arrow on the drawing
Thank you very much

I'm self-evident
Maybe I understood the question
the part between the two parts should be the quota 1"1/8
the bridge that is located on the outer radius of the semiboccola
in fact the two sides cannot be radial towards the center
and even perpendicular to each other
but quota 1"1/8 goes to aumnentare minimum 3rd per side
because being a piece that is produced by melting so you need a
model for foundry is the need for
add a sform angle to extract everything from a form of sand or resin
see sketch attached
Thank you very much

But that part is worked. could have an overmetal for the deform, and then be eliminated by machine.

I refer to that part between the two curved parts that measure 1 1/8 inch

hi ing..
I don't see the working symbol
But I want
sometimes for a superficial cleaning
you can also give
But maybe the prob of this piece is another
the two pins from dia3/4 to work them or you go with a milling and revenues with contouring
with a big moment tolerance
or join a bare type head of andrea
I think it would be easier and cheaper to make two holes
from 3/4 and insert du pins in acc.
p.s.
It's just a provocation to feed the discussion.
thank you 10000

Hi.
That's what I already indicated on the previous sketch.
Thank you very much

I think it refers to the face highlighted in red.
in the design the enchlinezine of the visible edge is not radial, even if there is that line of the quota to 15° prolonged until the upper broth of the faccai (red) that would presuppose it is a radial face. But you know... I do not know how to read nor write the radial representative.

You could make an arrow on the drawing
Thank you very much

but you claim too much:smile:; so the question would be clear to the first shot and there would no longer be neither guessing nor satisfaction to participate in a thread of potentially infinite length

the sform angle there should certainly be, but el design the two long sides of the bridge, those with the crude aspect of fusion, to be seen are parallel to each other with a fitting on the cylindrical face.
If these drawings have a didactic purpose I think it should be specified that there have been inserted various inaccuracies. of the series "find the error and correct". I think instead that, even in the past, those who asked explanations for similar exercises did not have the slightest notice of this.

View attachment 33320in the design the enchlinezine of the visible edge is not radial, even if there is that line of the quota to 15° prolonged until the upper broth of the faccai (red) that would presuppose it is a radial face.

You know exactly what I meant. I was very indecisive about how to draw it, since from the acenometry the design is not very clear:wink:

Hello marcof
It's always a pleasure to read
then the part in red is 15° compared to the axis
I think we have made a proper interpretation
when it concerns the long sides of the bridge
it is understandable that a designer looks well to put sforms or corners of puff
on a particular of which perhaps you know what it takes
but he does not know his engineering to produce it
back to an old discussion that is located in the forum "industrial press"
"For the sforms, the moldist thinks about it"
I don't think school exercises have all the meanness of having mistakes already defined.
I quote you
ehhhhh.... but you claim too much; so the question would be clear to the first blow and there would be no more or suspance of guessing nor the satisfaction of participating in a thread of potentially infinite length I think it's just a representational sketch to which the ally gives free vent to what he learned.
or do us a search and get busy to find a solution
and then teach me
what do we serve? ? ? ?
Thank you very much
