– The TNC 640 understands DXF fi les (option)
Why program complex contours when
your drawing is already in DXF format
anyway? You can open DXF fi les directly on
the TNC 640 in order to extract contours or
machining positions from it. Not only does
this save time otherwise spent on
programming and testing, but you can also
be sure that the fi nished contour is exactly
according to the designer’s specifi cations.
The DXF format—particularly the DXF
format supported by the TNC 640—is very
widespread, and is supported by all
common CAD and graphics programs.
After the DXF fi le has been loaded onto the
TNC from the network or a USB stick, you
can open the fi le in the fi le manager of the
TNC, just like an NC program.
As a rule, DXF fi les contain multiple layers,
with which the designer organizes the
drawing. So that as little unnecessary
information as possible appears on the
screen during selection of the contours,
you can hide via mouse click all excessive
layers contained in the DXF fi le. This
requires a keyboard with touchpad or an
external pointing device. The TNC can
select a contour train even if it has been
saved in different layers.
The TNC also supports you when defi ning
the workpiece preset. The datum of the
drawing for a DXF fi le is not always located
where you can use it directly as the
workpiece preset, especially when the
drawing contains multiple views. For this
reason, the TNC has a function with which
you can shift the drawing datum to a
suitable location simply by clicking an
element.
