from the chirone-torncasa we read from table that says that for a piece of our size the foundry in coarse land has tolerances ranging from +/- 0.5 to 7.2 mm; how is it possible that changing only the material of the model would have a tolerance almost close to the worst of the range of the foundry on earth?



since ours is only a pure theoretical exercise we say that it is not expected that fusion is mistaken

we have stopped to the grappa flavored with straw:smile:; the bug is to try!

Hi.
a polystyrene model with only one accidental contact is "feel"
shaping him in a bracket is a delicate operation
It can happen that the superficial coats of the cedin model or are inflated
Then there's the prob of his extinguishing without any sforms.
or remain in the bracket and burn it with gases that in addition to being harmful can damage the fusion
(and a great discussion that in this period involves all the operators of the sector)
this type of blades are made with models of excellent invoice
p.s.
for the grappa???? ? ? ? ? ? ?
it would be appropriate to try a walnut wood essence
you would make a big walnut

this 3ad has already exceeded the quota of 1100 visitors
congratulations were aroused a great interest
Thank you very much

if instead you used the wood (which moreover has an extraordinary perfume...) with that quantity of waste hypothesized by shiren you would aromatize us so much of that grappa to satisfy the body of the Aplini delgi for four generations

Maybe it's the second one. putting limits on the thirst of mountaineers is like asking them to tell you when they are drunk.

Well, if a friulano tells me I have to consider it gospel! :smile:

:
Tell me what it costs to draw a mathematical model in 3d
what gives you the customer must be done to adapt it to the needs of foundry
and then make an executive track 1/1 with all the sez
with relative construction technology?????? ? ? ? ? ? ? ? ? ? ? ? ? ?

Hello marcof
Hello Masses... .

But you should respond to this situation
if you have any employee
n° 2 drawings 3d drawing one of the finished piece and two of the melted piece with construction technology
put into the table with all the seeds
how much you want me

It's always a pleasure to read you
Thank you very much

 

[SHIREN]

We are talking about this
Thank you very much

Bye to all,
It's so much that you don't feel it, but we were busy with the exams. the fruit of today's work is the definition of all the specifications of the foundry: straightness, casting channels, etc. that we train you. What do you think? do you notice anything wrong or do you have any suggestions to give us?
Thank you very much

Hi.
I am displaying the attached sheet
weight shed 3.72 kg????????? ? ? ? ?
dimensions in mm or inches
the same thing for collar
channels????? ? ? ? ? ? ? ?
Thank you very much

 

[Reynolds vs. Grashof]

We hope that there will be all the measures now:

Hi.
How does a blade like that
weighing 3kg and 700 (3,700 kg)
40 mm x h 125
He doesn't even fill up.
but the important thing where are the points of application of the bats
the measurements of the bracket
you have to have from 50 to 60 mm of land between the perimeter of the model casting channels and out-of-model bats and the size brackets
I attach you an example of matarozze even if I know more suitable for spheroidal cast irons
Thank you very much

Hi.
How does a blade like that
weighing 3kg and 700 (3,700 kg)

the volume of the jet we calculated with the netfabb and there is 462,22 cm^3; we considered a density for the steel of 8 g/cm^3 and therefore the weight is 3721 g

but the important thing where are the points of application of the bats

for the application points we have placed them where the major module comes from the directional solidification accounts (i.e. zone 3 of the excel file); we still took a picture of the jet with the materozzes and raced it, along with a simulation made with the solidcast of the temperature trend, to the file below

thanks to all

Bye to all,

we are compiling an estimate of the production costs of foundry. The only voice we miss is the one about the brackets. Would you tell us how much a 315x250x125 mm bracket would cost?

Thank you very much

Thank you very much

as not all of us are experts or have congnition of foundry, could you be more precise? by trade? worked or raw? in disgusting steel, good, cleansing, anything? aluminum? ....

 

[Reynolds vs. Grashof]

we mean the trade brackets to make us the model and the foundry land

the costs of brackets on standard measures are difficult to define
because they depend on "numbers"
but never enter the costs to be prevented by mergers
are part of the "dote" of a foundry
different would be the speech if faced with a particular equipment or modeling
specific brackets should be built that would be borne by the customer and in exclusive use of the foundry
that you would build(from own suppliers) the brackets according to own needs
height width and interassesment of coupling
and consequently hooks for handling and locking/setting brackets
seems to be what every foundry
has its own wagon its own "mulets" their own chain ropes and their systems
and 99% are not good for other foundries
Thank you very much

 

[Reynolds vs. Grashof]

thanks for the answer,

Finally we also thought the same thing and for this we did not include the costs of the brackets in the estimate of costs (even because we couldn't find anything). We are now finishing off the particle removal part. we have liquidated quite easily milling and drilling, of which we have easily identified the parameters thanks to the catalogs of the various companies, while the question remains suspended regarding the flex. since in sacred texts the emery passes in the second floor, we would like to have advice on the following things:
-what type is most suitable for working conche (dates the reduced size of 85*100 mm): flex straight, angled, bench...
- what parameters should be taken into account? to us come in mind only the times (which we estimated in a half hour) and the various types of abrasives

Thank you very much

Hi.
for this operation the operator must equip the operator with a series of templates
possible metal even non-ferrous
whose perimeter geometry is derived from mathematical models
transformed into dwg and consequently obtain the templates with laser cutting or other
the final result depends on the number of transverse and longitudinal silhouettes
to keep in mind that the foundry has certainly required a few more mm of overmetal
in the conche area if not even some jobs - pottery - rmetal wholesale
to ensure fusion
need to use attached photo tools
with widia cutters (made in italy) that exist of various types and diameters
in the specific case round cutter (ball) diameter 12-14 maybe 16
in 1/2 hour????? ? ? ? ? ? ?
is realistically too little
the operator not and a cnc also has perhaps some physiological need
calculates that you have to mount and disassemble a series of cutters and diskettes in the market
to look at the various silhouettes and to evaluate the
the chip removed very small metal scales from prob and also bothers the operator
it must always be eliminated with air blow or with dry brushes
The infusion is still worse.
I say that if you give something more than two hours maybe it's better
Thank you very much
Good weekend
