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

Function
The purpose of the "Aligning milling tool" or "Aligning turning tool" function is to support
lathes with a B axis that can be swiveled. This functionality is designed for use with a specific
configuration of lathes or milling machines on which the tool orientation is implemented by a
swivel axis B (around Y) with associated milling spindle (C1). It is designed to be compatible
with both turning and milling tools.
In contrast to "Swivel plane", no rotation is effective in the active frame chain (WCS) in the
case of "Swivel tool" or "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.
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.
