Caution: Danger to the tool and workpiece!
Use FUNCTION MODE TURN to select a kinematic model
prepared by the machine tool builder, which is necessary for
the use of facing slide. With this kinematic model, the controls
executes the programmed X-axis movements of the facing slide
as U-axis movements if the FACING HEAD function is active.
This automatism does not work if the FACING HEAD function
is inactive and in Manual operation mode, which means that
X-movements (programmed or axis key) are executed in the X
axis. In this case, the facing slide has to be moved with the U
axis. There is a danger of collision during retraction or manual
movements!
