Twin turret lathe configuration

Hi,

it is possible to set up a dual turret lathe for linuxcnc?
They should both move independently, with their own tools and zero points.
I read somewhere that it needs to involve two separate machines, and need to sync the moves somehow.

there is a link herehere in case studies, but the link is broken:

Should I use XZ UW axes for the two turrets? is it possible? so G1 X10Z10 U10W10 would work ?

Anyone knows how to do it, or got some tips how should I begin developing it ?

Thanks

Ok, I understand that.
But how can program two different tools? They both would have different compensation.
Can I program somehow the use of two tools for different axes?
Or I need to set up the tool table, single tool number, but compensation on four columns, xzuw?
Or what would be the best approach?

Industrial machines have two CNC controllers because they use two independent G codes.
With just one controller, you have a G code for two independent turrets. In that case, you have to write two programs and then split and convine the G codes, which can be a nightmare and the result may not be optimal.

So G43.2 can be used If Im not mistaken.

Actually this machine will do the very same movement in a mirrored fashion on the Z W axes. But will use two tools so need to set up two compensation points.

So im thinking on writing a wrapper, which will simply negate the W axis, but it might not be hard to copy the XZ Params and turn them into X->U -- Z->(-W)

The tool offset table in Linuxcnc has separate columns for each axis. So if you are always using the same pairs of tools together then you can simply have the Z offset in the Z column and the W offset in the W column. (If tool 3 in the Z is always used with tool 3 in the W.) If the pairs of tools are not always the same then you will need to use a separate tool position for each, one tool with the Z offset in the Z column (and no W) and the other tool with the W (in the W column but no Z), then add the two tool offsets using G43.2. The same for X and U if needed.

Yes, it is a railway wheel lathe. Just didn't know how it is called, and approached the problem on a more generic way.

Thanks for the link, I will read it out.
