turning between shoulders

[torubychan]

hi to everyone, I introduce you to me that I am an engineering student who will ask some questions about this forum as I have to develop for an examination a working cycle of an entirely ideal piece. in this case my questions are 2:
1 according to you for pieces to be produced and aterial to be used, I start to work from a billet or do pieces by fusion with overmetals, stripes and soul courses?

2 How do I work the part between the 2 shoulders (flange)? on the sandvik site I have seen for example that you could have a reduction of linear diameter (creation of a conical surface) and then continue to return in a longitudinal way to the vertical face of the other flange, then turn the piece and remove all that had remained (sup. conica).
Is it a feasible thing? I know that my questions may seem stupid but I have no practical knowledge of these things.

I attach the design provided by the...

Hi.

with office 2003 I can't open the file... :frown:
can you put a .pdf? or save it in format that even who like me has office 2003 can see it?

Thank you.
Bye!

Yes, sorry

...to me it seems a simple piece to make cnc turning starting from bar.. .

the quantities indicated I believe do not justify costs of foundry with this material.

1 according to you for pieces to be produced and aterial to be used, I start to work from a billet or do pieces by fusion with overmetals, stripes and soul courses?

2 How do I work the part between the 2 shoulders (flange)?

now I ask you a few questions
1) is the piece round? quoted so it would be square
2) if it is round you have to make it completely lathe?

for what concerns the material you should start from bar if you have to realize it of lathe you can do the throat with a tool to channel then you have to equip yourself to realize the eccentric hole and do the grooves of recovery on a milling.
If you have a lathe with motorized tools you can think of creating the whole including eccentric hole and grooves.

hi and good luck with the exam:finger:

 

[Preparation-H]

Yes, sorry

If I understood the piece to be done well, it's like that. .
In my opinion the best solution is to make everything from bar on a cn lathe with motorized, with 2 squares realize everything.

Hi.
the info has available are too generic
get the piece from full bar involves some facilities
but full weighs around 7 kg
if you opt for a casting we are around 2 kg
with the fuse you can directly extract the four sunbeds
and the inner part of the bushing could remain crude of fusion
with the fuse would remain to make the outcenter hole and rectification of the shoulders
the number of 200 pieces for the construction of model and body case and acceptable
Let's make some accounts
price of wooden model 350€ more or less
24€ cost x 200 pieces 4800€
worked 0.30 minutes x 30€ h cost 15€ x 200 = 3000€
200 pieces should cost more or less 8000 €

If we deal with the "full" maybe we're a bit further away
Thank you very much

I would like to understand one thing, but the drawing was provided to you in that way by the teacher as well as to make the cycle also to fix the obvious graphic errors and quotation that are there. or it's all teacher's flour, I don't want to believe that a university teacher makes similar designs

thanks to all for the answers, unfortunately the design has been provided to me so from the teacher....cmq since the working cycle dv establish all I, I have no constraint, I can also choose what kind of machine to use for the processing. . . the only thing I was interested in knowing more is how to turn between the 2 flanges and it seems to me that I first have to do a throat with throat tool and then longitudinal turning, right? cmq the 3d posted by preparation-h is right (excentriivity of the large hole apart)

If I gave a design similar to a client of mine, it would choke on my face and the workshop (justly) would put me between the tips or bitten to a pallet.
You're gonna distrust him...

 

[Alberto.E]

if the teacher believes this is a correct design... then we are right in the m...

 

[torubychan]

ah, I forgot, since the tesin must also be accompanied by the sheet of workmanship, can someone tell me some simple and intuitive design program that allows me to draw the piece during the various phases of workmanship? (here from me the drawing exam is done with lines, squares and pencils)

Well, it seems to me that's the right thing, when one day you're going to make reliefs on a car and you don't even know how to hold a team and a pencil?
that you believe that there are not those who are still today disintegrated to the tecnigraph or with the teams and the line.

 

[torubychan]

undoubtedly the thing is right, indeed in some ways I prefer the manual design...but does catia okay cm program? or are there more simple?

 

[PierArg]

inventor is just as simple. . .especially for simple pieces.
I recommend inventor for simple solid modeling.

catia is the maximum: the best part is the surface module

 

[PierArg]

Sorry, I forgot.

I also started from the fuse.


but the purpose of the tesina is only to realize the piece or do you have to make sure that it has to possess particular mechanical properties?

Hi.
as simple cad 3d I recommend you alibre, on the site you can download the trial version working.

I allow myself, in response to such a design your tesina in the confrones of your teacher can not be that excellent...:finger:

 

[torubychan]

ahahahah vabbè but we got used to drawings, uses them only to give the idea of what you have to create, does not use them as a true concept, otherwise without the other views...cmq the piece must not have any particular mechanical characteristic, the purpose of the tesina is to produce the piece with costs in the norm performing operations according to a logical thread...I have added the rays of connection to avoid cracks and the slags.

 

[mariom]

I for processing between the two shoulders would use a tool with round inserts of radius 2 so avoid the finish pass.
However I agree with sharin costs less a fusion on the ground.
