(Activation and definition of the direction of the lift motion for reorientation during an active ORIPATH)
Note
A programmed retraction/lift motion is only executed, for:
● Once digit == 1 AND
● Length of the lift vector ≠ 0.0
x0xx No lift motion is executed.
x1xx Lift motion is executed in the direction of the programmed lift vector in the toolcoordinate system.
x2xx Lift motion is executed in the direction of the programmed lift vector in the workpiececoordinate

The lift vector refers to the coordinate system defined by the actual tool direction (z coordinate)
and the orientation change (x coordinate).
system. The lift vector refers to the coordinate system that is defined by the active plane (z
coordinate is the surface normal vector of the active plane) and the orientation change (x coor‐
dinate).
