scanning 3d e reverse engineering

[ceza]

Good morning.
I have a small workshop that builds (now very little) and repairs footwear machines.
Our machines require equipment we usually do. for now the process is as follows:
1)Customers send us plastic form
2)We make a hand model by cutting, stuccoing, adding buckets etc... (starting with plastic shape)
3)We send the model in foundry
4)Return aluminum casting
5)is processed on radial milling and drill (traditional)

I would like to understand if it could be worth it by automating the whole thing:
1)scannerreincrease shape
2)reverse engineering and modeling (to obtain the equivalent of model)
3)pass on the cam
4)Recover everything from a full aluminum block. .
all in low budget. Can you help me? I do not use any 3d cads and I would start from scratch....

interesting the question, but I see an insurmountable fear problem.

you are saying:

1] rent a tac-type laser scanner of hospitals

2] scan the customer's plastic positive, thus obtaining a cloud of points representing the enclosure of the machine

3] I add points from a software that creates triangles between contiguous points

Now, what turns out is an empty surface inside, but in the foundry they want the negative of the original form (to fill it with aluminum), so the question is: how to get a mold from a surface hollow object?

I have no answer to this dilemma, so I pass word.. .

No problem, it's something you normally do.
I just scanned a piece and treated it "with my inventor, who with the surfaces cannot be considered the maximum.

Bye.

for a single piece I don't know how worth it, scan it and redesign it all takes a lot of time.
consider that to go into a cam you have to draw with criterion, cure the surfaces for not having problems in the machine or in the generation of paths with a cam

We can talk about it, we do this job (reverse).
if you want some insight or advice contact me with a private message.

be kind, you could attach here in the forum an example couple, maybe in dxf:

- external surface (i.e. cable object)
- solid full derived from the above surface

thanks in advance

 

[ceza]

you are almost always single pieces. . .

Hi.
I attach you a couple of pictures of some work I've done

there are scans with relative mathematics; mechanical parts are more laborious to rematize while for sculpted surfaces (sometimes but not always) things are a little easier

I'm sorry, sir. What are you trying to prove with this?

The desperate ceza asked you to help him, not show him how good you are...

always waiting for the attachments of stefanobruno (sperando che non bluffi) and taking into account that the good ceza does not possess inventor, I place distinct greetings.

[ceza]

@ cadlandiano: I confirm that I have no inventor.
@ giorgio: but are all special facts in reverse? What kind of program did you do?

Here you are what you ask with such grace.

Thank you, stop.

 

[AntonioV]

Here you are what you ask with such grace.

really yesterday 3 November at 9:01 t'ho kindly asked for another thing: the triangular surface after scanning, as well as the resulting mold, both in vector format.

instead you gave me two 'things' in raster format, from which nothing concrete is visible.

I'm ignorant of this because I do another job, but I'd like to know more, so I wanted an aid. Fact by an expert like you, and not cryptics pdf...

I do other things.
I send the step & sat of the scanner and a version " mold " made on purpose for this discussion.
It's not the object I made, I'm not a moldist.

Bye.

(cont'd)

 

[stefanobruno]

( segue sat )

ecco il sat

 

[AntonioV]

thanks stefano, now the fog begins to thin: It's a world I didn't know, but it's worth approaching.

not being easy to find a free viewer of .stp files (This is does not work, at least under my windows xp_sp3), then I imported the .sat in autocad map2006 without problems.

double with version interactive of your model (to be seen with adobe reader 9 or higher).

He thinks I was just trying yesterday to generate something like this to go to the client without pc.
What did you do with it?
I downloaded the demo 30gg acrobat 7 but I couldn't get any results.

Bye.

 

[AntonioV]

I expected this perceptive question, at the bottom we speak the same dialect Bookianen: I used acrobat 8.0 pro of the company.

However I am leaving pdf_3d technology in favor of this here..

not to go out of the case, with which software did you triangulate the nearly 150000 points of the laser scanning cloud?

In the morning I try alone with map2006, let's see that monster comes out.

Unfortunately, I don't know, a person who builds the pieces that I draw (in addition, in turn, it has served someone who does the job, I think here in a torino )
I'll try to hear it later and let you know.

Bye.

 

[stefanobruno]

The name of the sw doesn't know it, it just seems that it's German.
What he told me is that the value of the complete scanning system is a few hundred thousand heur (3/500.000 heur).
level designer of body shop.
He tells me they also do third-party scans.

Bye.
