• In "Ø spigot", enter the approximate diameter of the spigot.
• Enter the infeed value in "DZ" to determine the measuring depth.
• In "Angle offs.", select entry "Yes" if you want to align using
coordinate rotation or select in "Angle offs." the entry "No".
• Enter the setpoint angle.
• Enter the setpoint positions X0 and Y0 to determine the point of
intersection of the connecting lines between the spigot center
points.
The setpoint angle refers to the 1st axis of the working plane (X/Y
plane). This input field only appears if you specified "Yes" for "Angle
offs."
4. Press the <CYCLE START> key.
This starts the automatic measuring process. The tool automatically
probes 4 points in succession of the rectangular spigot outer wall or
the outer wall of the first spigot if several spigots are to be measured.
After the measurement has been successfully completed, the center
of the spigot is determined and the "P1 stored" softkey becomes
active.
5 If you are measuring several spigots, then move the tool
approximately to the center of the second, third, and fourth spigot and
press the <CYCLE START> key.
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.
6. Press the or "Calculate" or "Set WO"softkey.
The length, width, and center point of the rectangular 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 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
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.
