cam software for milling 5 axes 3d scans

[Roberto85]

Good morning to all,

this morning doing some online research I came across this cnc forum and maybe you can help me out.
I work on a company that shapes the polystyrene for the creation of molds.
for more complex work we use a 5-axis mill for production using proe4.0 cad /cam
it happens very often of requests for the milling of scanned models then cloud of points /stl/mesh that obviously cannot be used except reverse engineering.
Can someone tell me some software specific to reverse, and a good cam that handles milling on models of this type?

everything is in correctly recreating the surface starting from the cloud of points, which however is a technique I would dare say "traumatic" because it belongs to that category of works in which there is not easy-way-out. (Get your hand remember the song of a rocky movie)

so you need a good nurbs modeler first of all... and I think of rhinoceros, one of the many.

for the cam.. you said you use the cam proe 4.0... I think I hope it's up to the task. otherwise I can recommend a good mainstream and multi purpose cad/cam such as alphacam... I have been working for years in the nautical furniture industry and, while recognizing its structural limitations, of the then version 7.0 (now we are at the 12th revision if not mistaken) I do not remember having ever said "ok with alphacam I can not do it".

thank you for the answer...the comparison to that song already makes me realize that it is not a simple thing to do.
we say proe has a good cam but has limitations in the milling of complex surfaces, i.e. it manages them but only through very small windows and for the calculation of the path puts us a life (and x life I mean even more than an hour) finishing also the memory available sometimes.
are there cads that manage to work mesh without making conversion to nurbs?

 

[c3kkos]

Surely yes; in my small surface modeling experience though I always preferred to avoid mesh. Also the cams I had to deal with had no problem with the nurbs, while with the mesh they were doing a bit of a bang... .

I think the use of mesh is more suitable for the realm of polygonal modeling, and less suitable for the production chain (i.e. cad-cam)

Hi.
If you just have to fresare stl models that pass you just have a cam that can work them.
powermill for example can also do it in 5 continuous axes without problems and also on complex models, also for large modelling machine tools, like cms and belotti.
there is also a module to fresare with robots like kuka, abb, etc. with more than 5 axes.

I use powermill that fresa without problimi stl files
