2 spigots The angle between the line connecting the center points and the
reference axis is calculated and displayed.
For "Set WO", the center point of the first spigot now corresponds to
the position setpoint. The calculated rotation is stored in the work
offset.
3 spigots The center point and the diameter of the circle on which the three
spigot center points lie are calculated and displayed. If you selected
entry "Yes" in "Coor. rotation", then angle α is additionally calculated
and displayed.
For "Set WO", the center point of the circle now corresponds to the
position setpoint. The calculated rotation is stored in the work offset.
4 spigots The spigot center points are connected diagonally and the intersection
point of the two connecting lines calculated and displayed. If you
selected entry "Yes" in "Coor. rotation", then angle α is additionally
calculated and displayed.
For "Set WO", the intersection point now corresponds to the position
setpoint. The calculated rotation is stored in the work offset.
2.6.10 Aligning the plane
You can measure an inclined plane of a workpiece in space and determine rotation angles α
and β. By subsequently performing coordinate rotation, you can align the tool axis
perpendicular to the workpiece plane.
In order to determine the position of the plane in space, three different points are measured
along the tool axis. To vertically align the tool axis, the "Swivel" function or the 5 axis
transformation (TRAORI) must be set-up at the machine.
In order to be able to measure the plane, the surface must be flat.
Precondition
You can insert any tool in the spindle for scratching when measuring the workpiece zero
manually.
An electronic workpiece probe is inserted in the spindle and activated when measuring the
workpiece zero automatically.
