Graphics during FK programming

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:

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

The contour element shown corresponds to the

drawing: With the SELECT SOLUTION soft key the

TNC inserts the desired solution with the NC block
FSELECT

n, where n designates the internal solution

number. You should not change the solution number

n by direct editing, but by restarting the programming

graphics and pressing the SHOW SOLUTION soft key

If you do not yet wish to select a green contour element, press the

END SELECT soft key to continue the FK dialog.

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

(soft-key row 3)

If you wish to use graphic support during FK

programming, select the PROGRAM + GRAPHICS screen

layout (see "Programming and Editing" on page 83).

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

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.
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.
