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 blank form with a large tool. The TNC
interrupts the graphics and displays the text ERROR in the
graphics window. The machining process is continued,
however.
