Selecting and saving machining positions
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.
If required, configure the basic settings so that the
TNC shows the tool paths.
Further Information: "Basic settings", page 290
Three possibilities are available in the pattern generator for defining
machining positions:
Single selection: You select the desired machining position
through individual mouse clicks.
Further Information: "Single selection", page 299
Rapid selection of hole positions with the mouse area: By
dragging the mouse to define an area, you can select all the
hole positions within this area.
Further Information: "Rapid selection of hole positions with the
mouse area", page 300
Quick selection of hole positions via an icon: Click on the icon
and the TNC then displays all existing hole diameters.

Select the file type
The following file types are available:
Point table (
.PNT
)
Klartext conversational 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.
The point tables (.PNT) of the TNC 640 and iTNC 530
are not compatible. Transferring and processing
on the other control type in each case may lead to
problems and unforeseen performance.
