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.
