Creating setup with machine where WCS is not oriented same as machine

[MarkusQ5465]

I want to create a setup where the WCS i not oriented the same way in A and C as the machine. But as far I can tell you can only move the fixtur and part in XYZ in relation to the machine, not being able to rotate around any axis?

In other words i have a fixture where the part attches to an angled surface in relation to the machine table. I want the WCS to be placed perpendicular to that angled surface of the fixture. The machine handles this fine with tilted work planes(G68.2) but fusion seems to lack the option to freely place a part in the setup in relation to the machine when it's rotated in any way?

If you connect your Fixture in the DESIGN with a Joint with the Origin, you have all the options to twist or move your device.

It is important to set the "Orientation" to "Model orientation" in the Setup.

This previous thread may also be of use https://forums.autodesk.com/t5/fusion-manufacture-forum/umc-400/m-p/13693975 It describes a situation where the programmer is using a pyramid fixture and wants to have per-part WCS that are normal to the pyramid faces.  In this case, the WCS is not aligned with the machine's C axis.

Thanks for response, I think that you might missunderstand what I'm looking for. In the machine my fixture offset (ex. G56) is not "0" in A and C axis therefor I cannot utilize machine simulation in Fusion because it seems that the WCS has to be aligned with the machine?

This thread here, will most likely answer your question, and, most likely, you wont like the answer: Haas UMC create work offset with B axis tilt 

In short, the MCS Z must align with the Z of the machine sim, or you have got to hack your post and possibly sacrifice 5 axis simultaneous toolpaths. Its a Fusion shortcoming.

I cannot see any restrictions when placing a part in Fusion.

Thanks

The restriction comes when you try to post out the actual parts.

What restrictions do you mean?

I have this 5th axis part we wanted to setup as it would be milled, but it has to be on the machine like this at g53 a0 c0.

Fusion will let me program it like this (the way it actually should sit in the machine to be setup) but WHEN you post it, then the limitation comes into play because it knows that part setup is not when the machine is at A0 C0. What we have to do is set the part up like shown below, then manually shift A by 90

If you go way back in my post history, youll see my thread about this.

Thank you very much for your support.

Why can't you programm this part with this Setup if it is clamped correctly in the machine?
