Free programming of straight lines
To display the soft keys for free contour programming,
press the FK key
To initiate the dialog for free programming of straight
lines, press the FL soft key. The TNC displays additio-
nal soft keys — see table at right.
Enter all known data in the block by using these soft
keys. The FK graphic displays the programmed
contour element in red until sufficient data are
entered. If the entered data describe several
solutions, the graphic will display the contour element
in green. See "Graphics during FK programming. "
See next page for the resulting NC blocks.
Straight line with tangential connection
If the straight line connects tangentially to another contour
element, initiate the dialog with the FLT soft key:
To display the soft keys for free contour programming,
press the FK key
To initiate the dialog, press the FLT soft key.
Use the soft keys (listed in the table at right) to enter
all known data in the block.
Free programming of circular arcs
To display the soft keys for free contour programming,
press the FK key
To initiate the dialog for free programming of circular
arcs, press the FC soft key. The TNC displays soft keys
with which you can enter direct data on the circular arc
or data on the circle center — see table at right.
Enter all known data in the block by using these soft
keys. The FK graphic displays the programmed
contour element in red until sufficient data are
entered. If the entered data describe several
solutions, the graphic will display the contour element
in green (see "Graphics during FK programming").
Circular arc with tangential connection
If the circular arc connects tangentially to another contour element,
initiate the dialog with the FCT soft key:
