FK programming graphics

To use graphical support during FK programming, select
the PROGRAM + GRAPHICS screen layout.
Further information: "Programming", Page 74
Program all of the contours before combining them
(e.g., with the SL cycles). You thereby ensure that the
contours are correctly defined and avoid unnecessary
error messages.
Incomplete coordinate data often is not sufficient to fully define a
workpiece contour. In this case, the control 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
between possible solutions in the standard view
If the displayed contour element matches the
drawing, then select this contour element with the
SELECT SOLUTION soft key
If you do not yet wish to define a green contour element, then press
the START SINGLE soft key to continue the FK dialog.
You should define the green contour elements as soon
as possible with SELECT SOLUTION to limit ambiguity for
the subsequent contour elements.
Showing block numbers in the graphic window
To show a block number in the graphic window:
Set the SHOW BLOCK NO. soft key to ON
