particular quotation, do you think it's okay?

[Er Presidente]

... how can I say how much I want them aligned? ?

It seems to me that everything has been thoroughly discussed and solved, only to punctuate:

the node is all in this question, the rigorous answer is a "positioning" of the holes with indication of their location.
but the problem does not move a millimeter, before starting to "position" the holes with its symbols, you must declare a reference plan, whatever it is will always be a reference face worked in tolerance and with a precision greater than that of the maximum error you want to have in the positioning of the holes.

The initial piece could be an extrusion of no one would have anything to say, but if you wanted them aligned?? How can I say how much I want them aligned? ?




Hello everyone

otherwise how should I do it? I am interested that the quota refers to between the 2 holes and not to the walls of the piece, that I can also be rather unprecise.

thanks and hello

Hi.
in the two posts there are two questions
who knows about workshop and must make such a plate
It's Palese
is silent
is taken for granted
that holes pass through the central axles
if processing on a cn the plate should be grasped in a clamp that in the machine and placed according to axes x or y
and normally it is grasped on the long side
the operator detects the resets according to this placement
I do not believe that specific tolerances must be specified
also because it seems that the platelet is made from extruded smooth
with saw cut
Thank you very much

I tell you and I add that when you make particulars of the genus you always align the clamp in milled, are mounted straight jaws adjusted to ensure the perfect alignment of the holes!
(obvious that these mountains only to realize the holes and not to cut all sides of the parallelepiped... )
consider also that in order to achieve what you have indicated the two faces must be parallel and therefore minimum braking smooth (indication ra1.6 on the drawing) or better still lapidellate (indication ra 0.8 always on the drawing).
with the support face on the team with the above mentioned two. and at this point the detail realizes it entirely of fresa.. .

you always try to start well with the job since you never know where you end up... but if you start already badly... :bekle:

Bye!

hi "mendic"
ohhhhh prob lies in the fact that who draws should give indications to the operator
But there are situations where increasing info only creates perplexity and time loss
If the plate is drawn from lisking in h11
370
the sides are already suitable to be grasped by the clamp
different would be the speech if the platelet is obtained from oxytaglio
It is obvious that those who draw know exactly where to get and how to make a platelet
and you should adapt in giving info to the operator
The speech is always relative is generic
you have to understand what this platelet is for.
I wish you a good night:wink:

you said well "ohhhh prob lies in the fact that who draws must give indications to the operator", and here of indications we had very few... :wink:

Good night to you too! :smile:

I'm sorry for the oct, but we're talking about quotas and I wanted to bring back the last experience.
there comes a design of a particle to cut laser with a serrated profile and this indication: 56 1/3 x 14 steps = 788 2/3
with the 788 2/3 which is the size in length of the particular.
What do you say? a remarkable act of fantasy or some norm that has escaped me...:smile:

Inches?
Inch measurements also break 1/16 1/8 3/4 inch......
Is that it?

20 mt and 32.1 mm for laser cutting :biggrin:

no are not inches.. .
Of course, 56 1/3 wanted to be 56.333333333333333333333333333333333
simple no?:wink:
explain to a cad that value not as well. . .
then obviously everything is resolved, but it is the way to approach the design that leaves basic.. .

I do not see why not put the 56.33 quota at just two decimals on the table, I believe that then there is no problem having also a tolerance +/- 0.05 (e.g.
more than the cad is to explain to the operator or who has to make the piece the type of quota put.. .

It's a very strange thing for us, but it's not for the Americans, it depends on what piece it is if it goes into use, etc.
I was wrong, better for michele nò?:smile:

 

[luigi.paiano]

oh my enjoy!!!do not present such a thing otherwise they will lincite you!!!put a geometrical tolerance of position of the two holes!!

 

[luigi.paiano]

if it is important that the two holes are aligned, make a hole reference and insert geometric tolerance on the other

 

[Mario SJPD]

I say mine because I don't think I read it

I tell you and I add that when you make particulars of the genus you always align the clamp in milled, are mounted straight jaws adjusted to ensure the perfect alignment of the holes!

two holes and I say two holes not three will always be and anyway aligned to perfection error 0 and say zero,zerozerozero periodic if the 20 does not have any type of tolerance or geometric or even numerical where is the problem?
Maybe I read bad now I'm going to reread.
However the quotation as well as being in my opinion wrong and definitely superfluous and for this useless and harmful.
as regards the 40h7 as an interasse and even ridiculous.
Good night

 

[Mario SJPD]

in fact it was already said albeit differently

I'm so sorry, but then that 0/+0.01 over what plan do you mean? If the reference supericie is rough (and therefore it will not be flat) how do you say that the two holes must be at the same distance with tolerance 0.01 mm?
I think if you don't spy on the surface that tolerance you indicate doesn't make any sense.
when you send the piece to test, you have to put the operator can make the measure: The first hole is at a certain distance from a plan that you do not know well what it is, the second hole must be at a distance equal to less than the tolerance indicated, but always with reference to a plan that surely so much plan will not be because it is a rough... You know, things aren't going.

much more professional, without reference plan your tolerance is useless if there is a plan you do courtesy to use geometric tolerances thanks.
Good night

ps: in my opinion there is no normative reference that prevents using letters to indicate the quotas any quota it is, it is only a more compact notation.

Hey, coast it,
I suggest you trust colleagues: they have already put you on the good road, on the need for a reference and finishing of the same.
I only intervene to make you notice that on all existing tables that report deviations relating to positions and quality of tolerances you find specific indication of their application: "values of holes scaffolding" or "values of tree scaffolding". How do you think of using letters to indicate an interasses tolerance?? the sense of tolerance positions is to define a shaft/hole coupling tolerance. for all other dimensional tolerances, of course, only deviations are used.
At this point I get the curiosity (that is woman, you know) to ask for the value of tolerance on the wholesse according to what criterion are you choosing it? How/where is the plate mounted?
and I repeat my suggestion to trust colleagues.
Good lav!
