Reverse engineering of extruded products
Reverse engineering of extruded products
(OP)
Hi All
I had an an interview with a company that extrudes some profiles of aluminum. The company was going to improve its work by doing reverse engineering on the products produced in the past, using a FEM software to redesign some new products . I was wondering if someone could tell me what could the details of such work be? since the die design for aluminum extrusion is done mostly by experience. so how would a FEM software help on this issue? I assume that anyway the finite element mrìethod would not precisely replicate the friction and contact

RE: Reverse engineering of extruded products
Are you proposing to use FEM to improve the product, or to improve the extrusion process?

The relationship between a sentence's Subject, Verb and Object are different in other languages, and this is frequently a source of confusion in the English of non-native speakers.
Another frequent problem is the excessive use of pronouns (he, she, they, it) when the subject of the sentence has not been properly established.
The language forum exists to help with this. Make use of it.
There seems to be a good and interesting question here, but it is not clear.

Greg, so you're saying that a FEM isn't required? Maybe it's a piece that they know how to design its tooling over the time?

You'd likely be amazed by the technology most small shops have today despite what they can do without. Production is driven by cost and quality, and the cost of FEA or other CAE tools is pretty cheap compared to the potential savings when it leads to a few product or production improvements. Sure, most analysis done today via CAE was once done via hand calcs and experience gained through iterative testing, it was also relatively inefficient as to people, time, and material. Not to say many businesses don't get by without modern technology but as the manufacturing world becomes increasingly competitive its getting pretty difficult to do so. I've seen far more shops go under than survive because they failed to modernize.

I do not fully understand the question. But if I assume that the work means analyzing extruded aluminum profiles to study how they perform and investigate possible optimization. That type of work probably means modelling the profiles and analyzing them for different load cases. For that type of work I would consider FEM is an exellent tool. Regarding friction and contact I would say that it can be simulated with the appropriate software and a competent user.
On the other hand, if the question relates to analyzing the extrusion process itself, that is not my area at all. I know that the metal forming of steel plates to different shapes (like car body's) can be modelled but regarding extrusion of aluminum, sorry. But I would not be surprised if it is done.
But I would not call what I described "reverse engineering" so I may have missunderstood completely.

Edit: When I read some later posts my impression is that the work probably relates to the extrusion prosess. So just ignore my comment, sorry.
