CNC Machine Kinematic Model Simulation

[jambrozy]

Hello,

I download some model of DMU machine, I wonder can I set a tool in machine spindle and  create a working motions with A, C axis? Greetings from Poland, thanks! 🙂

Okey, i found some informations in comments below video. It was 8 months ago, i check fusion roadmap but I didn't find any messages when team can implemented this solution.  I'll be very grateful if someone write on what stage of advancement is this. Thanks!

As you probably figured from the video you shared, Machine Simulation is not yet possible in Fusion 360. It IS on the Roadmap, but I don't know where it lands in order of importance. There is a lot of stuff being worked on and pretty awesome things to expect in the years to come

Though you can't do an actual simulation, I still tried to do as much as I can. I included the table and work holding model along with the part that I was trying to machine. I modeled the spindle but used a circumscribed circle for the square section of the spindle so that I had an extra safety buffer area around my spindle and would see if it would collide with my table.  Its not a true simulation but I wanted to try to check as much as I could.

I apply a similar solution when I programming Mazak HCN with rotary table, now I starting with 5 axis and it would be good to have machine components simulation. But I do not want to complain, i love fusion so as  seth.madore wrote:

"There is a lot of stuff being worked on and pretty awesome things to expect in the years to come"  Can't wait to see new options 🙂

Thanks all for quick answer, take care! 🙂

@seth.madore  Still no update on this? 😕

[jambrozy]

Still waiting 😞 but look on this update what fusion team do, anyone know how much vericut cost? ;o

What's New - Post Processors Edit

There has been active development working on bringing actual Machine Simulation into Fusion 360. We are closer now than we were a year ago, but I believe much work remains to be done. I do know that the team responsible for this is committed to getting it right, but I don't know, and couldn't share, when it will be completed and made available to the user base.

If you do 5-axis simultaneous, you pretty much need simulation...  but the Fusion machine simulation, if and when it comes, will most likely be simulating from the internal toolpath stuff, not the posted g-code file that will run on your machine.  This is good, much better than nothing, if you have 100% proven post processors that never do anything weird ever.  But if you want real simulation, you should get a real g-code simulator such as Vericut (as you mentioned) or NCSimul.  These are not cheap, but they save so much time on the floor (depending on the size of your shop).  Not only do they simulate actual g-codes that will run on the machine, but they decode the g-code before simulation to find any syntax errors, over travel, other such issues.  The floor runs so much smoother with a software like that.  I recommend NCSimul, but that is only because this is what we use, and are very happy with it.  I know Vericut does the same.

To answer your question about pricing, you have to get in touch with them, they have various modules (they can remove air cuts, reduce index clearance moves to a minimum acceptable level by you, etc, these are extra).  Just to give you a ball park though, the base software (that is all you need really) is around 10k, but again, they have promos etc, and maybe it depends how many machines you have etc, because machines are extra cost, and the price varies greatly depending on the type of machine.

Yes, we want Fusion machine sim!  but g-code sim is 1 step (actually a few steps) better, if you can afford it.

PS: @seth.madore if you think that machine sim inside Fusion will actually run from the posted g-code, please reply here and let us know!  That would be unbelievable value, but from what I've seen before (with other CAM softwares), it will at best run the CL file, which is not the same as the posted g-code.  Still very nice to have, specially with long time proven post processors!  We'll take that for sure!!

I can't wait to see this option on fusion. the sooner the better. Now I keep fusion as a side cam tool (learn new things and play with it)  but with the new changes to come I hope it will replace my actual work cam software . It will become a huge success. 

[seth.madore]

@DarthBane55 The intent is for the motion control to be driven by the Fusion toolpaths that have run through the post processor. So, not directly from the G-code, but from the post processor. Meaning the post will decide what solutions are chose (rotary values) and will also be able to send any custom moves it does into simulation

So, if you manually change X50 to X70 in the output, it wont change sim. But, if you do that in the post, sim will change.

Now, how that plays out in reality or what it adds to the technical challenges, that's well out of my purview 😉

[DarthBane55]

@seth.madore Thanks for the reply, that is great!  Seems that this will add tremendous value to the software and be extremely useful!!
