A graphical representation of a running program is not
possible if the microprocessor of the TNC is already
occupied with complicated machining tasks or if large
areas are being machined. Example: Multipass milling
over the entire workpiece blank with a large tool. The TNC
interrupts the graphics and displays the text ERROR in the
graphics window. The machining process is continued,
however.
In the test run graphics, the TNC does not depict multi-axis
operations during machining. The error message Axis
cannot be shown
appears in the graphics window in such
cases.
If your machine has a mouse, the status bar shows the
depth of any location on the workpiece when you move
the mouse pointer over it.
