Graphics - HEIDENHAIN TNC 426 B User Manual

11.1 Graphics

In the program run modes of operation as well as in the Test Run
mode, the TNC provides the following three display modes: Using
soft keys, select whether you desire:
Plan view
Projection in 3 planes
3-D view
The TNC graphic depicts the workpiece as if it were being
machined with a cylindrical end mill. If a tool table is active, you can
also simulate the machining operation with a spherical cutter. For
this purpose, enter R2 = R in the tool table.
The TNC will not show a graphic if
the current program has no valid blank form definition
no program is selected
With machine parameters 7315 to 7317 you can have the TNC
display a graphic even if no tool axis is defined or moved.
A graphic simulation is not possible for program sections
or programs in which rotary axis movements or a tilted
working plane are defined. In this case, the TNC will
display an error message.
The TNC graphic does not show a radius oversize (DR)
that has been programmed in the TOOL CALL block.
