Hi Teo,

For such complex simulation every constrain of your assembly needs to be perfect.

Anyway here is a link to the basic tutorial on how to do a simulation (Kinematics_simulator).

In this tutorial you´ll learn how to make a simulation with 4 parts, so its just so you have an idea how simulations work in catia. After you read the tutorial you will be able to do it with more parts, just like that video!

Hi Sebastian,

I do know how to simulate in catia, and I think I know it pretty good, but this problem is tricky. Yes the assembly has to be perfectly constrained but the simulation is extremly complex that constraints are not the problem, problem is in the visual representation of metal presing and gradually changing it's shape to the face plate of the mold. As I stated I'm courious and clueless, so are my mentors and it's the reason why I'm asking the community for help. Thanks for the reply, and if anyone know how to aproach the problem pleas do comment.

Strip layout change its form instantly, so I think that in this simulation he use 2 models of strip layout and control its visibility. Just watch carefully on 0:38. At first both shapes are visible (stock and formed part). When upper die reach bottom point then he hide stock model.

Also, it is possible that this guy simulate this via API automation, not via DMU Kinematics. He is top class API programmer according to his other videos. Also, DMU Kinematics require invest more money into licences, but it is not needed for stamping die design. It is overkill to buy DMU Kinematics license when you can inspect collision in every position of tool parts using scenes in assembly.

Hi Slavisa,

Thank you for the looking in to the problem and replying, I appreciate it. After looking again closely where you said, I would have to agree that he uses 2 "metal sheets", even now I think I could not succeed in simulating just the die compression on such a complex metal die. I'm not familiar with API automation, so I'll have to look in to it.

I was doing something like this for my assignmet (much simpler) and wanted to simulate it, but my mentors and I were confused, even how to aproach it. Thank you once again, and I'm shure I'll look in to the "API automation" and try somehow to realize this (mybe not so complex...).

Sincerely,

Teo Colovic.

Hello Teo,

API automation is not complex if you are familiar with object-oriented programming. I think this topic on my blog may be good introduction for API to you: https://cadslavisa85.blogspot.com/2018/03/mali-uvod-u-catia-v5-api-automatizaciju.html

Look for API, but be careful and try to not go into dead and and lose time.

If you do simulation for faculty/school project then I recommend to do tool kinematics via DMU. Education/Student license price is not problem. For strip layout, I think that you can control visibility using Knowledge Advisor Rules.

Hi Slavisa,

Thank you advice, I'm shure to look in to API cause of my curiosity :). I'll try not get lost in all that knowleg. And offcours I plan to visit your blog.

Sincerely,
