Application
In the program run modes of operation as well as in the Test Run
mode, the TNC graphically simulates the machining of the workpiece.
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 workpiece blank definition
„ no program is selected
The TNC graphic does not show a radius oversize DR that
has been programmed in the TOOL CALL block.
A graphic simulation is only possible under certain
conditions for program sections or programs in which
rotary axis movements are defined. The graphic may not
be displayed correctly by the TNC.
