Angular misalignment
Parallel and angular misalignment ( gap)
Parallel and angular misalignment can be determined in two rectangular planes. In order to eliminate
parallel and angular misalignment, the position of the moveable machine (M) needs to be adjusted in both
planes.
For horizontally mounted machines, the following needs to be applied:
The position of the moveable machine (M) needs to be aligned in the horizontal and vertical plane.
For vertically mounted machines, the following needs to be applied:
You need to discuss the use of the movement of a moveable machine under perspectives of operation
and efficiency with the machine operator. After that, you need to determine the arrangement of correction
planes.
Stationary machines (S):
The position of the machine is not changed in the course of measurement
and elimination of parallel and angular misalignment
Moveable machines (M):
The position of the machine is adjusted, in order to eliminate parallel and
angular misalignment
The measurement system determines the values for parallel and angular misalignment in the coupling (in
two rectangular planes) and the corrective values which are necessary for the elimination of
misalignments of the machine bases of the moveable machine (M). The following figure shows the
misalignment and corrective values for the vertical plane.
