FK programming graphics
If you wish to use graphic support during FK
programming, select the PROGRAM + GRAPHICS
screen layout, See "Programming", page 71
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 FK graphic displays the elements of the
workpiece contour in different colors:
Blue : The contour element is fully defined
Green : The entered data describe a limited number of
possible solutions: select the correct one
Red : The entered data are not sufficient to determine the
contour element: enter further data
If the entered data permit a limited number of 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 (2nd soft-key row) if you cannot
distinguish possible solutions in the standard
setting
If the displayed contour element matches
the drawing, select the contour element with
FSELECT.
