Path contours – FK free contour
programming

Fundamentals

Workpiece drawings that are not dimensioned for NC often contain

unconventional coordinate data that cannot be entered with the

gray path function keys. For example:

Known coordinates on the contour element or in its proximity
Coordinate data can be referenced to another contour element
Directional data and data regarding the course of the contour

You can enter such dimensional data directly by using the FK free

contour programming function. The TNC derives the contour from

the known coordinate data and supports the programming dialog

with the interactive programming graphics. The figure at upper

right shows a workpiece drawing for which FK programming is the

most convenient programming method.
