"grain scale" in developing sheet

[reggio]

hi, I press to have read the previous "sweep solid" "extrusion spiral" "helicoidal spring" etc. etc. without having found answer.

allego pdf with the test made (which only increased the questions. . )
In good substance I must obtain 2 separate sheets, calandrate to 90° that create a descent, then I must perform an equally distributed drilling not by step in "mm" but by step at angle and downhill, finally develop everything to cut to laser.

my test is made on a single part, but I will go to make it in 2 separate parts, possibly "delete" between them by excel's external calculation sheet (so that in the future, changing the ø and the corners will update the total that I will return), basically the problems I have encountered are 3:
1) What do I use to then develop?
2) how to repeat drilling based on an angle (type circular repetition but following a profile)
3) how to correctly align the holes (they must always look towards the central axis).

I thank you in advance for your help

to develop snail plates you can try using sheet metal (calandered type) or loft plates. I made it with the loft sheet, but it's a little crazy. try with the calandrates, if you can post the native file I see to give you a hand.

I am not convinced that I fully understand your request :biggrin:. .
However take a look at this model of "chip" from sheet metal tape:
the natives: View attachment CHIOCCIOLA.rarand some images: I did it on the fly, "to feeling", also this system is a bit slender but the result eventually gets it.
definitely there is a more rapid and direct method.. Maybe we hear the most experienced.

greetings and good work

... then... (excuse the break but here if you do not pass from one project to another continuously you may not miss. . )

the example of sampom is "almost" perfect, you understood very well what I meant:
Question 1 and 3 are fully answered: I can develop and the holes are correct :d
missing the 2, i.e. I have the need to repeat the drilling pointing a step in corners (I could calculate the step and insert that, and I will do it if there is no other way) and not a step in mm ... among other things the known angle is "in plant" while we descend with the drilling, then.... eh So how can you act? ? ?

now I would also like to add 2 sheets (up and under to get the profile to "c" as here:http://www.cad3d.it/forum1/showthread.php?t=13458) only that in the old example it was all + easy as on a single plane, here instead it is not where to lean... and then: do you manage to achieve the development in plan also of these profiles?

ps I also wanted to ask if and what are needed "elica/spirale2 and 3 and surface-filled1 and 2", I "explained" immediately and cut with a line: Do you need it for qlc that I didn't understand or it's just because you made it feel?

In fact you are right, I had never had the opportunity to try before and in the rush I came to the result following a very difficult road. Those two propellers served me to build the filled surface that I used as a cutting limit. in fact the cut I made it stupidly from the edge of the sheet to those surfaces.
much better (and fast) cut "diagonally" directly on the face of the sheet "explained" (and the nice is that I told you that the processing on the development is done in that way :biggrin, as I seem to have understood you; good!

I'm thinking about the holes with angular pitch. I can't think of anything. You could also do them with a repeat led by a curve, but I should try to see how to assign the corner. the fact is that they are not arranged radially on a plane, but "up" of a tot at each fraction of turn. Perhaps with an equation or table excel..
But sure you can't help it? You don't make them do it directly to the laser or even machine, but on the "planned" sheet? In this case I find it more convenient to give a linear step that is however the result of the angular division on the circumference tract included in your sheet strip (even here I used an equation, without having to approximate with decimals).
Tell us how you were going to make those holes.

the other question to build a sort of "c" along a propeller I fear that it is difficult to achieve. in the sense that with swx you can do it, with the surfaces or even with a helical sweep (apart from the development of which I am not sure), but in the workshop the speech changes; the sheet should be "svergolata" and "advitata", the inner edge shortens and the outside stretches. .
But wait, at the end of the day it would be a cochlea and how they do that, too.
I remember now that some time ago had posted a file with the solution of the development in the plane of the coclees/eliche. I see if I can repeat it and tell you.

then, I made some using the surfaces + the sheet loft is however rather "macchinoso" but you get it. using the loft does not change what the sense of thickness is, just reverse the surfaces. the beautiful is, that unlike this example, you can do + turn in with a single dish.
Now I can't post an example because I don't have the license available. As soon as I have a moment, I'll look at you and put something on.

for the repetition of the holes I recommend the repetition guided by the curve, I think the most suitable among those available. But I exhort all users in subscriptions to ask for some improvement on repeats (which I have done + times but on this have not yet satisfied me).

In proe, for example, you can combine linear and circular repetitions and you can do it from the night of time. possible that solidworks corp does not want to add this simple function? Break all the boxes. for what I will ask to open an ad hoc discussion, who has time, want and is in subscription read and send request through the dealer, the more we are and the better it is.

Bye.

keep burning:View attachment Nuova cartella.rarI did it with the suggestion of re_solidworks (which I thank for the tip:smile: Does it look like the waterpark slides, maybe that's why you had to freeze? :biggrin with a sweep surface (long a helix) and the sheet loft.
It works! you can also develop in the plan for laser cutting the profiles "top and bottom".
I had to give some adjustments to make everything concentric/tangent for coupling together, but all in all is not even too laborious.
However, I recommend that you also make the "rampes" in several sections such as vertical "costes" (this is always thinking of construction/mounting).

for the holes instead do not arrive to the solution "angular" you want . I'm sorry.

I do not post my example, you did exactly what I had done.:finger:

already, it no longer allows me to download it.. I don't understand why

I'm sorry, but I'm on vacation with my laptop, and that file is on the fixed.

Who knows if re_solidworks saved him and can put him back?

Thank you re_, perfect!
but how will the original link not work anymore?
uploaded attachments are "expiration"?

Of course not. I'm here doing my deck and you ran away (handbook):tongue:

joke (obviously). attachments do not expire, I do not know if something happened during server transfer, try to report it to the admin.

 

[reggio]

Here's the sampom file.

very kind (as always).

is not the first time I happen to find broken links, since they updated the forum qlc day ago...

*then the admin and moderator(s) therefore are not the same person*

good holidays, good rest or good continuation, say good fresh :d
