axioms with measured measures

[genesis1975]

Good morning to all,
It is my second discussion, I wanted to say that I have been working for about a year and a half in a company that produces mechanisms for sofa beds and there was still no technical office; I started by taking the measurements of the levers that make the cinematism that opens and closes the sofa that becomes read, and I started with team and line to take the measurements of the interassis between the levers, measuring the rubbings of the same, the fittings to go then to make the assemblies of the skeleton of the couch putting the washers and the thicknesses that use in production to have the distinct base with the used components.
the result is that in the drawing the thicknesses are not the right ones, sometimes intersect with the levers, sometimes there remains empty space, sometimes the levers are intersected...from the outside the overall is good, but if you go to see near you notice these things, but if I want to make the distinction with the details really used in the assembly I have to do so... but then my manager complains about these traits... but how can I do

I would put the models in place so that there are no problems and I would remake the designs. listed. As the stocks of the old details are exhausted (I think they have a warehouse) , I send in production the new ones, so maybe the climbers can or do their job without having to leave for each piece.. :

should also young the final product. .

depends a lot on what you've been doing.
looking from outside would be to say that the best thing would be to have the drawings in place and on these build the pieces.
Consider however that when you mix a piece you have measurement errors but especially if you melt a single piece the share you collect could be in the entire range of tolerance (or even out but this is a further speech). We assume that a certain amount has a nominal value of 20+1/+0 if you take any piece and read 20,65 does not mean that you should shape it with that value.
but today the pieces that are produced do not have their constructive design? also only 2d, made also by hand by some good soul in recent decades?

no previous design, the overalls currently on the market I have to do them, starting from the parts always made by me based on the surveys of each piece made with row caliber and team

I have to do them by relying on my measurements

a cad serves just that, design an efficient and working system.
with 3d you can also display object movements, analyze interference and study solutions more easily
models all according to the measurements detected and then suitable and correct the project until it becomes working

but will never coincide with reality in my case

 

[MassiVonWeizen]

So you want to rebuild the reality even if this proves to be projectually wrong and the operation is due to solutions echoed at the moment with imaginative remedies and of which no trace is taken?

 

[genesis1975]

What do I do to make you fools, too? with what angle? with someone that better approach reality?

 

[MassiVonWeizen]

Why are they foolish?

 

[genesis1975]

some are levers made with a crushed and perforated tube at the ends of which the only thing a little safe is interassesed to realize the cinematism, they are full of folds and twists... but also the others do not work straight, maybe when they are tricked they are forced to work a little foolish... I guess the tolerances are not well defined. I need to see... I don't match the straight levers because they obviously don't work straight... and even measure them with the ruler. . .

 

[MassiVonWeizen]

I would do the project from scratch. but from scratch.

 

[Stefano_GS]

Sorry to insist.
but today the purchases of components and processes like you do?
even imagining to buy a commercial tube any this will have its characteristics (diameters, straightness, ovation, thickness etc.). if the holes do you, even with the simplest of the column drills somewhere (in a notebook closed in the closet near the machine) some operator will be marked the interests, that in some way it will control (on the famous notebook it will be written that up to a certain quota will go well, quota that maybe the editor yelled behind that time that just the pipe could not be mounted).
remake the project from scratch would be my suggestion, but if you can't investigate a bit with who is on the field and on the piece and you will see that a lot of information albeit empirical, albeit handed down by mouth as the legends will come out. even to avoid all times the mental fatigue of having to understand how to make people tend to give themselves rules, especially if no one is concerned to do so

 

[genesis1975]

we are the company providing mechanisms for sofa bed of a famous brand, so what we do is considered to the height but the tolerances of the presses folds, the tranchers and of the molding sheet are not really granche by nature...in addition in the installation a beautiful tricky and maybe the levers go in tension and bending, you also see to eye that they are not working perfectly straight also because of the limits of a connection with the jugs...

 

[MassiVonWeizen]

But then what is your question?

 

[genesis1975]

even if a lever is inclined to a single degree multiplied by a length of 30 cm, you get some mm of difference in thickness...or not?

 

[genesis1975]

I'm afraid you can't do differently, but as there are those who complain if a washer goes into internetration in the drawing I wanted to ask more experienced people. .

 

[MassiVonWeizen]

ask a nice clear and understandable question, if you need to add a sketch or image. because for auctions saying that everything is okay, things have to be like they are not okay.
people can be as expert as you want, but if we stay on the theoretical image in which for me the washer has infinite positions in space and an infinite lever forms I can describe infinite solutions.
Maybe you're the one who modeled badly and you're not able to move the washer that in reality is tangent to the tube/lift.

 

[Stefano_GS]

I really struggle to understand what you want to get or what opinion.
Of course I would complain if even only a washer goes into interconnection, because you will agree with me that that configuration is not a representation of reality and that it is not usable for any purpose.
I try to hypothesize:
1. you need to have the drawings of the individual parts more or less adhere to reality, then model them as best you can and don't do any together
2. you want a model of the axieme to get a distinct base, then model the parts so that in the virtual environment everything is coupled properly even if then in reality the pieces are not so
3. You need a full project, then you have to do everything right. heavy carpenters also model in 3d and it is not that we talk about tolerances from cnc machine.

but can the client not share with you the project?

 

[MassiVonWeizen]

if in the 3d something goes into interference and in reality it is not so you can quietly talk about modeling error.
