A laser-based measuring system that allows precise measurement of large components for the tensioning and alignment of workpieces in a machine tool, and measurement of component vibrations. A signal generator emits two rotating laser beams which form a plane each. One beam is a measuring beam the other is a equipment zero signal. The intersection of the two beams on the workpiece is used to effect alignment. When properly aligned the two beams are superimposed and display no flickering. If not properly aligned as indicated by a coordinate monitor, the adjustment plate and fixture together with the micrometers are to adjust the plane's position.
