1 Introduction
1.4 Graphics and Status Displays
In the PROGRAMMING AND EDITING mode of operation the pro-
grammed macro is displayed as a two-dimensional graphic. During free
contour programming (FK) the programming graphic is interactive.
In the program run (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 selectable via soft key.
On the TNC 415 B and TNC 425, workpiece machining can also be
graphically simulated in real time.
The TNC graphic depicts the workpiece as if it is 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 does not show the workpiece if
• the current program has no valid blank form definition
• no program is selected
With the 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.
