Aligning turning tools - only for G code program (CYCLE800)

Function
The "Align turning tool" and "Align milling tool" functions support combined turning-milling
machines with a B axis that can be swiveled.
In contrast to "Swivel plane", no rotation is operative in the active work offsets in the workpiece
coordinate system in the case of "Align tool". Only the offsets calculated by the NC and the
corresponding tool orientation are effective.
The maximum angular range for "Align tool" is +/- 360 degrees or it is limited by the traversing
range of the participating rotary axes. Technological limits are also placed on the angular range
depending on the tool used. When aligning the tool, the data of the tool is calculated based on
the tool orientation using the CUTMOD NC command. For a turning tool, the calculation
involves the cutting edge position, the holder angle and the cut direction.
Definition of the β and γ angles
The beta and gamma angles orientate the turning tools. They refer to the WCS. If the WCS
corresponds to the MCS, the tool data remains unchanged for β=0° / γ=0° (cutter position,
holder angle, ...).
The definition of angles beta and gamma depends on the particular machine. In the initial state
of the machine kinematics for turning, a turning tool can be orientated according to Z or X.
Initial state of the machine kinematics
The tool axis is aligned in the Z direction.

Tracking
The position of the tool tip is maintained during swiv‐
eling.
No tracking
The position of the tool tip changes during swiveling.
