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.
