Rapid selection of hole positions by entering a diameter
Select the mode for choosing a machining
position. The TNC hides the layers shown in the
left window, and the right window becomes active
for position selection
Open the dialog for diameter input: enter any
diameter in the pop-up window displayed by the
TNC
Enter the desired diameter and confirm it with
the
ENT key: the TNC searches the DXF file for
the entered diameter and then shows a pop-
up window with the diameter selected that is
closest to the diameter you entered. Also, you can
retroactively filter the holes according to size
If required, configure the filter settings see "" and
confirm with the
USE soft key: The TNC loads
the selected positions into the left window (and
displays a point symbol)
If necessary you can also deselect elements that
you already selected, by dragging an area open
again, but this time while pressing the
CTRL key
Save the selected machining positions to the
clipboard of the TNC so that you can then insert
them as a positioning block with cycle call in a
plain-language program, or
To save the selected machining positions to a point
file, enter the target directory and any file name in
the pop-up window displayed by the TNC. Default
setting: Name of the DXF file. If the name of the
DXF file contains special characters or spaces, the
TNC replaces the characters with underscores.
Alternately, you can also select the file type: Point
table (
.PNT), pattern generator table (.HP) or plain
language program ( .H). If you save the machining
positions to a plain-language program, the TNC
creates a separate linear block with cycle call for
every machining position (
L X... Y... M99). You can
also transfer this program to old TNC controls and
run it there.
Confirm the entry. The TNC saves the contour
program in the directory in which the DXF file is
also saved
If you want to select more machining positions
in order to save them to a different file, press
the Cancel selected elements icon and select as
described above
