6.6 Path Contours—FK Free Contour Programming
Graphics during FK programming
Incomplete coordinate data often are 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:
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:
U Press the SHOW soft key repeatedly until the correct
contour element is displayed.
U If the displayed contour element matches the
drawing, select the contour element with FSELECT.
Select the green contour elements as soon as possible with the
FSELECT soft key. In this way, you can reduce the ambiguity of
subsequent elements.
If you do not yet wish to select a green contour element, press the
EDIT soft key to continue the FK dialog.
If you wish to use graphic support during FK
programming, select the PGM + GRAPHICS screen layout
(see “Program Run, Full Sequence and Program Run,
Single Block,” page 8).
White 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.
The machine tool builder may use other colors for the FK
graphics.
NC blocks from a program that you called with PGM CALL
are displayed in another color.
