Learn how to program multi-spindle mill-turn machines with NX.


(view in My Videos)

Tech Tip presented by Uwe Edlinger, Siemens PLM Software



  • Use of the Generic Motion operation to program mill-turn features such as slots
  • Transfer the workpiece from the main spindle to the sub (secondary) spindle
  • Use of specialized controller commands such as the Sinumerik’s FXS command (Travel to Fixed Stop)

I build OKUMA LT2000EX (main spindle+sub-spindle, lower and upper turret, 2 channels) with NX 9.0.3. For part transfer from main sindle to SUB-SPINDLE I use short subprogramm with one line only:



   transferParts ("MAIN_SETUP","COUNTER_SETUP");



THATS ALL. Working.


But, when I try to repeat a same for NX8.5.3 mp10 - a lot of surprises!

First - "transferParts calling with wrong arguments". Ok, I open samples OOTB projects sim15, I see different lines in subroutine






I have modifyed my CSE-tree, no error messages, but - no part transfer.....


Can you advise me the basic moments for part transfer with NX8.5?


Thank you!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The Part Transfer method in the video shows the use of a UDE.

I think there are new ways of doing motion control in Turning, e.g. Part eject, chuck open and close, part transfer between spindles.


Do you know where I can find this group of operations, I have seen some in a template file but not able to figure out how to create them from scratch.


Thanks in advance

Hi Tony,


have you looked into the available NC Simulation samples shipped with NX CAM?

The Sim15 machine shows the current best practise how to setup NX CAM for doing part transfers, open/clos chucks, etc.


Open the part directly



OR use the new machine pallettes in NX12
