Measuring 3 circular spigots
The workpiece is in any orientation on the work table and has
three spigots. 4 points are automatically measured at the three
spigots and the spigot centers are calculated from them. A circle
is placed through the three center points and the circle center and
circle diameter are determined.
If an angle offset is selected, base angle of rotation α can also be
found.
•
Measuring 4 circular spigot
The workpiece is in any orientation on the work table and has two
spigots. 4 points are automatically measured at the four spigots
and the spigot centers are calculated from them. Two spigot
center points are each connected diagonally and the intersection
point of the two lines is then determined. If an angle offset is
selected, base angle of rotation α can also be found.
You can only measure 2, 3, and 4 circular spigots automatically.
1. Attach any tool for scratching to the spindle.
2. In "Machine Manual" mode, select the "Meas. workp." softkey.
3. Press the "Spigot" softkey.
4. Press the "Rectangular spigot" softkey.
5. Specify whether you want "Measurement only" or in which work
offset you want to store the zero point (as described under
"Measuring an edge manually", step 5).
6. Specify the position setpoints (X0/Y0) of the spigot center point P0.
7. Traverse the tool to the first measuring point.
8. Press the "Save P1" softkey.
The point is measured and stored.
9. Repeat steps 7 and 8 to measure and store measuring points P2,
P3, and P4.
10. Press the "Set WO" or "Calculate" softkey.
Calculate
The length, width, and center point of the rectangular spigot are
calculated and displayed.
The set position of the center point is stored as a new zero point with
"Set WO". The tool radius is automatically included in the calculation.
