Reference plane for defining the traversing direction for LFTXT

At the point of application of the tool to the programmed contour, the tool is clamped at a

plane which is used as a reference for specifying the liftoff movement with the corresponding

code number.

The reference plane is derived from the longitudinal tool axis (infeed direction) and a vector

positioned perpendicular to this axis and perpendicular to the tangent at the point of

application of the tool.
