9. Specify setpoint positions X0 and Y0.
These determine the point of intersection of the lines connecting
the hole center points.
10. Press the "Cycle Start" key.
The tool automatically contacts 4 points in succession around the first
inside wall of the hole. When measurement has been successfully
completed, the "P1 stored" softkey becomes active.
11. Then move the tool approximately to the center of the second,
third, and fourth hole and press the "Cycle Start" key.
The tool automatically contacts 4 points in succession around the
inside walls of the holes. When measurement of P2, P3, and P4 has
been successfully completed, the "P2 stored", "P3 stored", and "P4
stored" softkeys become active.
12. Press the "Set WO" or "Calculate" softkey.
Calculate
The hole center points are connected diagonally and the intersection
point of the two connecting lines calculated and displayed If you
selected entry "Yes" for "Angle offs.", angle α is additionally calculated
and displayed.
With "Set WO", the intersection point now corresponds to the position
setpoint. The calculated rotation is stored in the work offset.
You can measure and align rectangular spigots, and one or more
circular spigots.
•
Measuring a rectangular spigot
The rectangular spigot must be aligned at right-angles to the
coordinate system. By measuring four points inside the spigot you
can determine the length, width, and center point of the spigot.
•
Measuring 1 circular spigot
The workpiece is in any orientation on the work table and has one
spigot. You can determine the diameter and center point of the
spigot with four measuring points.
•
Measuring 2 circular spigot
The workpiece is in any orientation on the work table and has two
spigots. 4 points are automatically measured at the two spigots
and the spigot centers are calculated from them. Angle α is
calculated from the connecting line between both center points
and the reference axis, and the new zero point that corresponds
to the center point of the first spigot is determined.
