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 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 MPs 7315 to 7317 you can have the TNC display a graphic even
if no tool axis is defined or moved.
Using the new 3-D graphics you can now also graphically
display machining operations in the tilted working plane as
well as multi-sided machining operations, provided that
you have already simulated the program in another view.
The MC 422 B hardware is required to be able to use this
function. In order to increase the speed of the test
graphics on older hardware versions, bit 5 of MP7310
should be set to 1. This deactivates functions which were
implemented specifically for the 3-D graphics.
The TNC graphic does not show a radius oversize DR that
has been programmed in the TOOL CALL block.
