Glad you got things figured to get a part working.

 

Your latest question is all based on whats supported on the control.

 

In my shop at http://www.rmbproducts.com/ I have a CMS Router that fully supports setups exactly as @Steinwerks suggests.

http://www.cmsindustries.us/en/products/composite-material-aluminium-and-advanced-material-working-systems.c12350/high-speed-5-axis-cnc-machining-centres.12351/ares.12362

BTW SpaceX has 15+ CMS Routers in a much larger scale used in this exact same scenario to build many of their rocket parts.

We are able to use standard Fanuc Fixture offsets G54-G59 or G54.1-G54.99

We have multiple parts in different locations all managed through a unique fixture offset.

We probe only when we have to. Our parts are rotation molded plastics and we do 5 Axis simultaneous trimming.  If the parts have variance AND we have to control relative locations we probe. ALL Compensation is managed through TCP via G43.3 on our machine in conjunction with the previously mentioned Fixture Offsets.

 

Hopefully your situation is similar. If not you may be forced to use the static method I previously mentioned.

You part or multiple parts can still be anywhere in the working travel envelope. The trick here is the WCS Origin must be modeled with respect to your center of rotation. And the shift of where the part and its origin must also be determined. Then on the machine each part must be setup with the same shift replicating the offset.

My hobby 5 Axis machine works this way at home. My machine supports 3 Axis Fixture offsets but it does not do 5 Axis compensation other than with the G54 Fixture Offset.

 

I hope this helps!
