Defining contour descriptions
With the DECLARE CONTOUR function you enter in a program the path for
programs from which the TNC draws the contour descriptions. In
addition, you can select a separate depth for this contour description
(FCL 2 function):
 Show the soft-key row with special functions

Select the menu for functions for contour and point
machining
 Select the COMPLEX CONTOUR FORMULA menu.
 Press the DECLARE CONTOUR soft key.
 Enter the number for the contour designator QC, and
confirm with the ENT key.
 Press the WINDOW SELECTION soft key: The TNC
superimposes a window where you can select the
program to be called.
 Select the program with the contour description with
the arrow keys or by mouse click and confirm by
pressing ENT: The TNC enters the complete path
name in the SEL CONTOUR block.

Define a separate depth for the selected contour.
 Conclude this function with the END key.
Alternatively you can also enter the name of the program with the
contour description or the complete path name of the program directly
via the keyboard.
With the entered contour designators QC you can include
the various contours in the contour formula.
If you program separate depths for contours, then you
must assign a depth to all subcontours (assign the depth 0
if necessary).
