7.6 Path contours – FK free contour
programming (option 19)
Fundamentals
Workpiece drawings that are not dimensioned for NC often contain
unconventional coordinate data that cannot be entered with the
gray dialog keys.
You can enter such dimensional data directly by using the free
contour programming function FK, e.g.
If there are known coordinates on or in the proximity of the
contour element
If coordinate data refers to another contour element
If directional data and data regarding the course of the contour
are known
The control derives the contour from the known coordinate
data and supports the programming dialog with the interactive
FK programming graphics. The figure at upper right shows
a workpiece drawing for which FK programming is the most
convenient programming method.
