“Problems” – aligning and centering – links
Centering is where the axes of two round workpieces or tools are moved so that both lie in the same plane.
Aligning is where a line is moved so it is parallel to plane or where two planes are moved so they are parallel to each other. In these cases the angle between the identities is zero. But it is also possible for alignment to involve any other angle.
