Swiveling aligning tool - only for G code program (CYCLE800)

Function
The purpose of the "Align milling tool" or "Align turning tool" function is to support combined
milling machines - lathes with a B axis that can be swiveled.
This functionality is specifically addressing certain configurations of milling machines, which
have been expanded by turning functionality. Tool orientation in the turning mode is realized
using a swivel axis B (swiveling around Y) with an associated milling spindle (e.g. C1). It is
designed to be compatible with both turning and milling tools.
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, this
involves the cutting edge position, the holder angle and the cut direction.
The use of the "Align milling tool" function is restricted to milling operations in parallel with
the axis (face, peripheral machining) at a machine with a B axis that can be swiveled. If
milling is to be possible on any swiveled machining plane, then the "swivel plane" function
must be used.
