Visualization tool for simulation a cutting process

Anonymous's picture

For my NC-Programmingsystem i am looking for a simulation tool, wich can simulate a cutting process. The "Library" does not need to read g-code. I give the stockinformation and the path the tool should go. Then the Library should simulate this. Does anybody know about such a library, or is there somebody who would devolop it with (for) me (of cource not for nothing).

Hi, Christian

about the topic you can search it in the forum with keyword „simulation“. I think, the kernel of simulation tool has to be developed by yourself. Roughly speaking, there exist two different approaches to implement the NC simulation. One is the discrete methode, e.g. dexel, G-Buffer, etc. The another method is swept-volume method. The corresponding papers you can find it on the “”.

As I know, there is no simulation package in OCC, which can give you a direct access to do your work. I am working at this topic, maybe in half year, I will release some code about the swept-volume method.

I have actually developed one before I got cascade but that only displayed the tool trail during the animation but I wanted to simulate the solid cutting action. I tried using cascade boolean operations after computing the swept volume of the tool between two points and the performing a cut with the part solid. But as the tool advances the boolean operations get more complex and time consuming. Then I searched the web with the key words solid, similation,milling etc. I have come to know that this method of boolean operation is not effective and the commonly used methods are the z buffer and the stencil buffer methods using OpenGL. Now I am trying to find out exactly how. Please let me know too if anyone gets some info. Best Luck!

i am also doing the same thing at the moment and have also the same problems as you!
Did one of you find more efficient?
Please let me know.

Now,I'm will do the cutting simulation.I want to use the OCC,but I find it is very slowly.Can you give me some ideas??

If you could read Japanese, you may look at, it is a commerical level free NC simulation/verification software(Free SDK for third party also). The software has English version, though the homepage is written in Japanese only.
