The position and orientation of the turning tool can be changed by rotatingswivel axis B (around Y) and the tool spindle.In contrast to "Swivel plane", no rotation is operative in the active work offsets in theworkpiece coordinate system in the case of "Align tool".The maximum angular range for "Align milling tool" is limited by the traversing range of theparticipating rotary axes. Technological limits are also placed on the angular rangedepending on the tool used.When aligning the tool, using the CUTMOD NC command, the tool data are calculated onlinebased on the tool orientation (positions of the B axis and the tool spindle). For a turning tool,this involves the cutting edge position, the holder angle and the cut direction.Name of swivel data setSelecting the swivel data set or deselecting the swivel data set.The selection can be hidden by the machine data.For "Swivel plane" and "Swivel tool" / "Set tool", only the swivel data sets are available forselection where no B axis kinematics, turning technology has been set."Swivel tool" / "Align tool", only the swivel data sets are available for selection where B axiskinematics, turning technology has been set.Machine manufacturerPlease refer to the machine manufacturer's specifications.Approaching a machining operationWhen approaching the programmed machining operation in the swiveled plane, under worstcase conditions, the software limit switches could be violated. In this case, the system travelsalong the software limit switches above the retraction plane. In the event of violation belowthe retraction plane, for safety reasons, the program is interrupted with an alarm. To avoidthis, before swiveling, e.g. move the tool in the X/Y plane and position it as close as possibleto the starting point of the machining operation or define the retraction plane closer to theworkpiece.
