Free contour programming

Functionality
Free contour programming enables you to create simple and complex contours.
A contour editor (FKE) calculates any missing parameters for you as soon as they can be obtained from other parameters.
You can link together contour elements and transfer to the edited part program.
Technology
The contour calculator for turning technology provides the following functions for this purpose:
● Toggling between radius/diameter programming (DIAMON, DIAMOF, DIAM90)
● Chamfer/rounding at the start and end of the contour
● Undercuts as transition elements between two axially parallel straight lines, where one runs horizontally and the other
vertically (Form E, Form F, thread undercut according to DIN, general undercut)
Contour editor
Proceed through the following steps to open the contour editor window:

3. Select the desired program file, and press this key to open it in the program editor.
4. Press this softkey to open the contour editor window.
5. Initially, you define a contour starting point (see Section "Defining a start point (Page 271)").
6. The contour is then programmed step by step (see Section "Programming example for turn-
ing application (Page 281)").
