tabelle varies

[tmp_fra]

Good morning to all, indeed now good evening.

I open this tread because I didn't seem to have seen anything like this around.. but I confess I looked very quickly.

If so it could be useful to collect here the various tables that are not always included on all manuals.

I have a nice question to ask you:
today a worker of a manual lathe, asked me if I give him a table to calculate the gradients of conical pieces according to the starting and arrival diameters; I'm sure some of you can have an idea of what you're talking about, can you give me a link or tell me where I can find the table you're talking about?
hoping it's not a book legacy 30 years ago.... I look forward to your help.

Good evening to all!

praiseworthy initiative bad example

I don't think it's changed in the last 30 years.
However, in the first pages of the designer's manual that I don't have in my hand, I think there's something.

 

[tmp_fra]

I know it's simple trigonometry, but as it told me about a table I've never seen wondering!
I can't tell him to put himself there every time with the calculator if he doesn't even know what breast and stuffy tangents are... .

ok then check on the manual!thanks for the straight!

 

[Marcogeo]

Tell him to go buy a good manual... maybe learn something.

@ marcogeo : avoid responding I prefer!

Well, you give her a table, don't you?

 

[Preparation-H]

Well, you give her a table, don't you?

Yes, but I think it comes a mastodontic work, calculates that in addition to the two different diameters you have to take into account also the distance.
If I have a diameter 10 and a diameter 20 with a height of 10 I will have a corner, if this will be 20 another angle and so on... all for every millimeter... Be mad.
at this point better the calculator... :wink:

Bye!
p-h

 

[sampom]

... all for every millimeter. . .
p-h

..eh,
Just every millimeter. solutions are "infinite".
if the lather had on the banquet an open pc on an excel sheet would be very easy and immediate.. smaller there are also programmable calculators.
but to think of having a "carton" to hang on the wall is unrealizable.

But excuse me, would it not be better that the designer (as should) noted on the table also the angular quota? ?

first rule: avoid in the most absolute way that the operator should make calculations, even simple.. We don't just think about cn.

in the ideal world would be beautiful but apparently not all that is provided to him has all the data that should have!

and let's not forget that not everyone is so updated to have necessarily a cnc, someone still has to do things in their hands.

However the problem was that you have to do either hand accounts or that you have to know how to do them, the question was if you know the existence of a table with something similar. I don't know exactly how it was that I'm in trouble describing it... but he told me that he had correlations between angle diameters and lengths, and according to this table he made the necessary to make the conicality to the lathe.

Maybe I should ask other operators.

Thanks for the advice.

cut...the existence of a table with something similar. I don't know exactly how it was that I'm in trouble describing it... but he told me that he had correlations between angle diameters and lengths, and according to this table he made the necessary to make the conicality to the lathe.

manual of the designer - r.rossi - ediz. hoepli.
my, third edition of the 90, brings your tables to page 219 onwards.

I have the 13 if I don't remember badly, but today I've never seen it. I'll try to deal with it! Thank you so much!

I said that right away. .
I am old and when it comes to turning I immediately think of flyers and graduated drums:smile:

....but he told me that he had correlations between diameters angles and lengths and according to this table he obtained the necessary to get the conicacy to the lathe. .

Of course there is a correlation, but always mathematics:conical is the relationship between the difference of diameters and the distance between them.. and you have the tangent of the corner. So you have to get the cotangent. . always calculations to do. it is not obligatory to know trigonometry but at least have sufficient experience to use a scientific calculator (or consult the old tables).
This is what I mean, drawing up an immediate reading table is impossible; you can graphically represent a cone trunk that highlights the values to be inserted, but then there is to be accounted for.
I repeat, we put in the odds even the corners.. However smile.. how much these corners can serve to a "traditional" turning machine; the angle rotation of the turret is very aleatory, you know precision.. but the unified norms of design have always responded to everything; the classic and unique indication of condom 1:tot It solves perfectly. when you know that dead length the variation of diameter is of a six millimeter, and ideal for the "traditional" that tari and controls with the comparator.
but these things should teach her the lathes to us, not vice versa.

I know what you refer to, but those tables indicate series of "standard" conicals for general mechanical uses, beyond that there is the infinite precisely. then they are all degrees, minutes, seconds.. and turn the tower on.. Fortunately they are coupled to the relative value 1:a above, then recur to the comparator as just mentioned.

It's all true, but I thought, because he's talking about "already seen but I don't remember where" he was referring to those.

edition 13?
I'm not talking about baldassini.

Hello everyone
I think that perhaps the request for a table that carries for each degree and for each mm the difference in mm of the deviations
has been interpreted a moment beyond the real intentions of the operator
that from how it is understood is a tradizonal machine tool operator
from which I deduce that he is also one who knows his profession

who knows about turning and turning well that the gradations marked at the bottom of the turret have a tolerance of more or less 0.50°(0°30')
common thing on every type of machine traditional tool or on any
tool carrying a graduated scale

then the operator does not ask for a specific table
but only a lot of values for the main corners and standard lengths used in the workshop
from which it can or could deduce dimensional deviation in error
and consequently increase or decrease the angle placement error
which then goes has corrected with suitable tools (a comparison)
All is called
deductive numerical reasoning
if we add
that if the center of the carbide cutter is not exactly with the axis of the counterpoint you can have degrees values that in some cases bring you out tolerance even quite

I wish you a good weekend
thanksmille:smile

I think you hit the mark... you know where I can track a table that is inherent to his demands?

I am definitely confused!!! Forgive me! !
