Measuring 3-D basic rotation
The misalignment of any tilted plane can be measured by probing 3
positions. The
Probe in plane
function enables you to measure this
misalignment and save it as a 3-D basic rotation in the preset table.
Operating and programming notes:
The sequence and position of the touch points
determines how the control calculates the direction
of the plane.
With the first two points you specify the direction
of the reference axis. Define the second point in the
positive direction of the desired reference axis. The
position of the third point determines the direction
of the minor axis and tool axis. Define the third
point in the positive Y axis of the desired workplace
coordinate system.
1st point is on the reference axis
2nd point is on the reference axis, in a positive
direction from the first point
3rd point is on the minor axis, in a positive
direction of the desired workpiece coordinate
system
