1 Introduction
407
1.4 Graphics and Status Displays
In the program run operating modes (except on TNC 407) and test run
operating modes, the TNC provides the following three display modes:
• Plan view
• Projection in three planes
• 3D view
The display mode is selected with the soft keys.
On the TNC 415 B, TNC 425 and TNC 426, workpiece machining can also
be graphically simulated in real time.
The TNC graphic depicts the workpiece as if it were being machined by a
cylindrical end mill. If tool tables are used, a spherical cutter can also be
depicted (see page 4-10).
The graphics window will not show the workpiece if
• the current program has no valid blank form definition
• no program is selected
With machine parameters MP7315 to MP7317 a graphic is generated
even if no tool axis is defined or moved.
The graphics cannot show rotary axis movements (error message).
Graphics during program run
A graphical representation of a running program is not possible if the
microprocessor of the TNC is already occupied with complicated machin-
ing tasks or if large areas are being machined.
Example:
Stepover milling of 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.
