Machine simulation does not currently check for machine collisions

[mads4ever]

Hi,

I'm using machine simulation, and everything works fine, except that machine-machine collisions are not detected.

I get the following message in the simulation dialog:

"Machine simulation does not currently check for machine collisions"

My machine model has "air" between all moving parts.

Is this feature missing? Or do I need to upgrade to machining extension?

I've looked here https://help.autodesk.com/view/fusion360/ENU/?guid=Fusion_CAM_how_to_generate_multi_axis_machining_5... but it doesnøt say anything about machine-machine collision.

That is correct, we do not yet check for Machine Collision. However, we do have it working and have it released to a select group of users, and it (collision detection) will find its way to the general public before too long

Hi,
Is the previous message still relevant 1 year later? because the message "Machine simulation does not currently check for machine collisions" still appears. 
Are there still plans to open this feature to the public?

Yes, we are still working on machine collision checking. In fact, if you're a member of the Insider Program, you can test this out now:

I'm having this exact issue. The simulation is showing my spindle head like two feet above the tool during simulation. Any updates on this?

@JaykReed83 

Our next update is going to have some really nice Machine Sim updates

Would you be able to share a sample file and your machine config that shows this issue? I'd like to try it out in our internal build and see if your problem remains.

[JaykReed83]

I'm not sure if this is the right way to do this. Let me know if it doesn't work.

Hi,

It's not a problem with machine simulation, you just have your machine setup incorrectly.

You can see here the Tool Attachment point is on the Table rather than the spindle face

Spindle attach should be here:

You also had the part attachment point incorrect but that is less important, it should probably be here:

If you fix that is simulates correctly.

[JaykReed83]

Thanks! I made the adjustments you suggested. It definitely fixed the issue with the spindle head being way above the tool during simulation. 

The part attachment adjustment helped too. Ive been having to manually move the part location every time i update anything. So, that helped too.

However, I'm still getting the "Machine Simulation does not currently check for machine collisions" warning. I'd really like that to work since this 5ax trunnion is brand new and i really dont want to lose my job for crashing it. lol

This is correct for the time being. Sit tight though, I think you'll be quite pleased with an upcoming update 😉
