Here is the first file which is the main sheet (flattened) with 2 musical notes stamped via forming tools: DemiCoqueHauteNotees.SLDPRT (564.2 Kb)
and here is the second forming tool to train the instrument: FT-DemiCoqueHaute.zip (163.7 KB).
Solidworks refuses to create this part for me and here is the error message that is returned to me:
" This function will create disjoint bodies. Multiple sheet metal bodies are not supported "
The big musical note on top is easily doable because on a flat surface but the other notes, I can't form them on the sheet metal once stamped with the big forming tool. On the other hand, with the flat sheet metal, it's easy to stamp the notes but it's impossible to form the instrument with the second forming tool.
Could you please help me, guide me to succeed in forming this sheet metal part?
I don't see the point of using the SolidWorks sheet metal module to model this instrument. This module is not very efficient for stamping, even if it offers some shape functions.
From what we can imagine of your part, a volume definition makes it possible to obtain a very similar geometry in a few functions. Sufficient?
I'm amazed!! Indeed, it would look a lot like this!!
In fact I went for sheet metal because it will be made from sheet metal quite simply and I tried to design it as if I had the sheet metal in my hands.
What is the point of doing 2 surface shifts? Is it to make the 2 pitches of notes and make a boss-extrusion up to these offsets?
The 3D sketch allows you to draw straight lines that will be perpendicular to the sketch planes?
In my idea I will have to send the notes in the other direction, that is to say inside the shell and not outside, for this I should probably do an extruded material removal and then a shell, as you have you, it should work.
It's a great job, thank you very much, I already see a lot more clearly to "try" to make my piece!! Thank you very much because I was struggling with my sheet metal part.
I'm back here to publish my final result and get your expert opinion.
The two staggered surfaces serve as limits for extrusions to " follow " the overall shape of the shell. Aesthetically, it seems preferable to a flat background. It's a matter of taste...
3D sketching makes it easy to generate sketch plans for notes.
The solution is similar for intaglio notes, by shifting the boundary surfaces inwards, and placing the sketch planes outside the base shape (inversion of the dimension by 10 mm in the sketch5).
Ok I'll do as you tell me, I've already redone the lower part because it's less complex. I was clearly inspired by your file that I redid entirely in order to understand what I was doing, I prefer.
Aesthetically, I prefer that it follows the offset surface, it's closer to the real design reality.
Thank you so much for your help and for the two files, it's really cool to you, especially on a Sunday
Have a good day and I'll get back to you here once I've made good progress in the project, if it might interest anyone else.
I am looking to improve the creation of notes on this instrument. What you proposed to me @m.blt was really very good and in order for it to stick even more to the reality of what I would like to achieve, I will have to take each note created to make them more in line with the reality of the device.
Could you help me because I've been trying for 2 days and I admit I can't make the notes please?
Attached is a screen with 2 notes, one that you had made and one that I am desperately trying to do, circled in blue.
As an attachment, my previous proposal completed by two " notes " (Note3 and Note4 folders) which resemble those of the photo of the instrument: central spherical part, flat perimeter or offset from the general shape.
Really thank you very much for the speed of your work.
The two constructions of the peripheral notes as well as the one of the central note above are interesting because I had not thought of making them like you.
However, there is a small detail that does not fit 100%, which is that they are systematically oval notes and not round (well, just one note in the whole range is round to be exact). I should have said it but I didn't think about it before.
And I think that's why I'm struggling so hard to achieve this removal of material, I tried to draw an elliptical profile to make a swept boss, starting from the cuts previously made, but I find myself with surfaces that intersect and that prevent me from finishing the function.
I will try to take your steps and adapt them to the dimension and shape of the notes by doing a swept material removal with the help of a " construction " ellipse.
I'll get back to you to show you what I've managed to do (well tomorrow the day is busy and work is fast approaching so if I'm not active quickly I'm sorry).
Thank you very much once again for the work. It's great, really!!
(I edited my post 10 times sorry, we'll blame it on fatigue)
3D drawing is one thing, making it is quite another. This type of instrument is always made by hammering for reasons of cost first but especially of sound because the voicing is also done with a flame.
The information always arrives in the end: the shapes of the notes are based on ellipses... The attached model proposes a solution (Note3) based on a smoothing removal of material. All that remains is to adjust the depth of the various removals, as well as the position, orientation and dimensions of the ellipse axes.
Hi @m.blt , thank you very much I'll look at this in the evening or tomorrow and I'll tell you. Really it's great thank you thank you !! it looks great like that at first glance!!
And good evening, I'm closely analyzing what you have done and I think that this solution will be the right one in order to have as true a rendering as possible.
I didn't know about the "SMOOTHED MATERIAL REMOVAL" feature and it's pretty interesting. I didn't think I'd achieve this hollow in this way, thank you very much for the help and discoveries I was able to make thanks to you.
I'm going to take my few "notes" by doing so.
Really thank you to this forum and thank you to you @m.blt !!
