Selecting and storing machining positions
8 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.
8 In order to select a machining position, click the
desired element with the left mouse button. The TNC
indicates possible locations for machining positions
on the selected element with stars. Click one of the
stars: The TNC loads the selected position into the
left window (displays a point symbol).
8 If you want to specify the machining position at the
intersection of two elements, click the first element
with the right mouse button: The TNC displays stars
at the selectable machining positions.
8 Click the second element (straight line, complete
circle or circular arc) with the left mouse button. The
TNC loads the intersection of the elements into the
left window (displays a point symbol).
8 To save the selected machining positions in a points
file, enter 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 contains special
characters or spaces, the TNC replace the character
with an underline.
8 Confirm the entry: The TNC saves the contour
program in the directory in which the DXF file is also
saved.
8 If you want to select more machining positions in
order to save them in a different file, press the
CANCEL SELECTED ELEMENTS soft key and select
as described above.
You must use the touchpad on the TNC keyboard or a
mouse attached via the USB port in order to select a
machining position.
If the positions to be selected are very close to one
another, use the zoom function.
