FK programming graphics

If you wish to use graphic support during FK
programming, select the PROGRAM + GRAPHICS
screen layout.
Further Information:
Incomplete coordinate data often is not sufficient to fully define
a workpiece contour. In this case, the TNC indicates the possible
solutions in the FK graphic. You can then select the contour that
matches the drawing.
The control uses various colors in the FK graphics:
blue: uniquely specified contour element
The last FK element is only shown in blue after the departure
movement.
violet: not yet uniquely specified contour element
ocher: tool midpoint path
red: rapid traverse
green: more than one solution is possible
If the data permit several possible solutions and the contour
element is displayed in green, select the correct contour element
as follows:
Press the SHOW SOLUTION soft key repeatedly
until the correct contour element is displayed.
Use the zoom function if you cannot distinguish
possible solutions in the standard setting
If the displayed contour element matches the
drawing, select the contour element with SELECT
SOLUTION
If you do not yet wish to select a green contour element, press the
START SINGLE soft key to continue the FK dialog.
Select the green contour elements as soon as
possible with the SELECT SOLUTION soft key. This
way you can reduce the ambiguity of subsequent
elements.
Showing block numbers in the graphic window
To show a block number in the graphic window:
Set the SHOW OMIT BLOCK NR. soft key to SHOW
stellen (soft-key row 3)
