3-D view
The workpiece is displayed in three dimensions. If you have the
appropriate hardware, then with its high-resolution 3-D graphics the
TNC can also display machining operations in the tilted working plane
as well as multi-sided machining operations.
You can rotate the 3-D display about the vertical and horizontal axes.
If there is a mouse attached to your TNC, you can also perform this
function by holding down the right mouse button and dragging the
mouse.
The shape of the workpiece blank can be depicted by a frame overlay
at the beginning of the graphic simulation.
In the Test Run mode of operation you can isolate details for
magnification, see “Magnifying details,” page 579.
 Press the soft key for 3-D view. Press the soft key
twice to switch to the high-resolution 3-D graphics.
This switch is only possible once the simulation has
finished. The high-resolution graphics show more
surface details of the workpiece being machined.
The speed of the 3-D graphics depends on the tooth
length (LCUTS column in the tool table). If LCUTS is defined
as 0 (basic setting), the simulation calculates an infinitely
long tooth length, which leads to a long processing time.
If you do not want to define LCUTS, then set MP7312 to a
value between 5 and 10. This way the TNC internally limits
the tooth length to a value which is calculated from
MP7312 times the tool diameter.
