4.6 3-D Line Graphics
(FCL 2 Function)
Function
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.
In order to find the error location quickly, the TNC shows the currently
active block of the 3-D line graphics in a different color in the left
window.
To switch the screen layout to displaying program blocks to the left
and 3-D line graphics to the right, press the SPLIT SCREEN key and
PROGRAM + 3D LINES soft key.
