   C axis rotation 
You can turn the C axis through a specific angle to enable 
subsequent machining operations to be performed at a particular 
position on the end face or peripheral surface.  
The direction of rotation is set in a machine data code. 
  Please also refer to the machine manufacturer's instructions.

  Scaling 
You can specify a scale factor for the active machining plane as 
well as for the tool axis. The programmed coordinates are then 
multiplied by this factor.
