Function
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 three 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, or
„
no program is selected.
The graphic simulation is not possible for program
sections or programs in which rotary axis movements are
defined. In this case, the TNC will display an error
message.
