Thats one of the contentions. The original tool spec was for a surface finish of 2-4Ra, the surfaces to me appear to be as-edm'd to me, which cannot be good. We have other dies that have been coated with TiN, it didn't seem to do much good/bad for us.
I'm currently running a process by which a carbide die is yanked through a 4340 tube (2.5" od, 1.6" id) that is .05 larger than the initial hole. The carbide tools are G30 (tungsten carbide), and the 4340 is tempered to ~Rhc 21+-1, the length of the tube is approx 9". Typicall pull forces...
This seems the best fit, and most diverse group:

I had a similar issue.
When I started SW, I would get some tools and not others. It turned out to be some wierdness with the add-ins and the order they were taking licenses.
Our company has different quantities of licenses for various features. In my case, I had both CosmosWorks Adv. Pro...
Thanks for the tips folks, here's what I did:
Cosmos works, and the data fits with initial hand-calcs (within reason). But its slow to process nonlinear, dynamic models, and my results should still err on the conservative side.
I modelled the two parts at a very small distance apart (just...
Thank you for the explanation. I'm using the non-linear, dynamic, section of 2008 - I've been assured that its fully capable of this type of simulation, but I'm not completely convinced as of yet.
I've gotten the two bodies to impact, but here's another oddity. Depending on the distance...
I setup another simple excersize to try and trouble shoot. 4 hrs to crunch this thing.
Two parts, one slides in the other, the point at which they should impact, they dont. Rather, the moving part that should impact the first, travels FAR clear of the stationary part, and THEN out in the...
the vac bag is going to apply a known static pressure to the laminate, so a uniform pressure applied normal to all 'exposed' surfaces should do.
In reality, the bag will put other stresses/loads onto the part due to a 3d volume being inside of a bag that cannot truly conform to the object, will...
CosmosWorks Advanced Pro 2008.
the ultimate goal of this is to study the interactions of a two body sliding assembly. one part is fixed, the other slides in 'guide rails' and is sent into action by a shock load (think automatic rifle).
In preparation for this, I've been trying to familiarize...
