Function
TOFRAME
orientation. This means that the user can retract the tool in the Z direction without risk of
collision (e.g. after a tool break in a 5-axis program).
The position of the X and Y axes is determined by the setting in machine data MD21110
$MC_X_AXES_IN_OLD_X_Z_PLANE (coordinate system with automatic frame definition).
The new coordinate system is either left as generated from the machine kinematics or is
turned around the new Z axis additionally so that the new X axis lies in the old Z/X plane
(see machine manufacturer's specifications).
The resulting frame describing the orientation is written in the system variable for the
programmable frame ($P_PFRAME).

These frames are programmed with the
