4.6 Measuring the workpiece zero

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.

After the measurement has been successfully completed, P2, P3 and P4

are stored and the softkeys "P2 stored", "P3 stored", and "P4 stored"

become active.

Press the "Calculate" or "Set WO" softkey.

The length, width, and center point of the rectangular spigot are calcula‐

ted and displayed.

For "Set WO", the setpoint position of the center point is stored as new

zero point. The tool radius is automatically included in the calculation.

The diameter and center point of the spigot are calculated and displayed.

For "Set WO", the setpoint position of the center point is stored as new

zero point. The tool radius is automatically included in the calculation.

The angle between the line connecting the center points and the refer‐

ence 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.

The center point and the diameter of the circle on which the three spigot

center points lie are calculated and displayed. If you have selected "Yes"

in "Coor. rot.", angle α is additionally calculated and displayed.

For "Set WO", the center point of the circle now corresponds to the posi‐

tion setpoint. The calculated rotation is stored in the work offset.

The spigot center points are connected diagonally and the intersection

point of the two connecting lines calculated and displayed. If you have

selected "Yes" in "Coor. rot.", angle α is additionally calculated and dis‐

For "Set WO", the intersection point now corresponds to the position set‐

point. The calculated rotation is stored in the work offset.
