3-D line graphics
Application
Use the 3-D line graphics to have the TNC show the programmed
traverse paths in three dimensions. A powerful zoom function is
available for recognizing details quickly.
You should especially use the 3-D line graphics to inspect programs
created externally for irregularities before machining, in order
to avoid undesirable traces of the machining process on the
workpiece. Such traces of machining can occur when points are
output incorrectly by the postprocessor.
The TNC displays traverse movements with
FMAX in blue in the 3-D
line graphics.
You can use the 3-D line graphics in Split-Screen mode or in Full-
Screen mode:
To show program blocks to the left and 3-D line graphics to
the right, press the SPLIT SCREEN key and PROGRAM +
GRAPHICS soft key
To show the 3-D line graphics on the entire screen, press the
SPLIT SCREEN key and GRAPHICS soft key.
