2-74
You can measure rectangular pockets and one or more holes and
then align the workpiece.
•
Measuring a rectangular pocket
The rectangular pocket must be aligned at right-angles to the
coordinate system. By measuring four points inside the pocket
you can determine the length, width, and center point of the
pocket.
•
Measuring 1 hole
The workpiece is in any orientation on the work table and has one
hole. You can determine the diameter and center point of the hole
with four measuring points.
•
Measuring 2 holes
The workpiece is in any orientation on the work table and has two
holes. 4 points are automatically measured in both holes and the
hole 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 1st hole is determined.
•
Measuring 3 holes
The workpiece is in any orientation on the work table and has
three holes. 4 points are automatically measured in the three
holes and the hole centers are calculated from them. A circle is
placed through the three center points. The circle center point and
diameter are determined from it. If an angle offset is selected,
base angle of rotation α can also be found.
•
Measuring 4 holes
The workpiece is in any orientation on the work table and has four
holes. 4 points are automatically measured in the four holes and
the hole centers are calculated from them. Two hole center points
are diagonally connected in each case. The point of intersection
between the two lines is determined from this. If an angle offset is
selected, base angle of rotation α can also be found.
You can only measure 2, 3, and 4 holes automatically.
