ABSTRACT:
A laser alignment control system comprises a method and apparatus wherein a rotating member such as a spindle can be properly aligned with a workpiece for manufacturing operations thereon. The system comprises a laser whose beam impinges on a target with the laser and target being interchangeably mounted on a spindle and a "master part". Information from the target is fed through interface circuitry to a computer which calculates an "effective target" relative to the shim feet under the movable master part or spindle. This "effective target" gives the system capability for aligning the operating member both as to coincidence of location and appropriate incident angle with points within the workpiece which are physically inaccessible. The computer outputs information onto a multiplicity of display screens wherein an operator can align the spindle with the "master part" axis by a series of shimming movements. The major steps of spindle alignment comprise making the ways of the wingbase supports for the spindle straight, adjusting the wingbase ways such that they are parallel to the "master part" axis, making the spindle axis parallel to the "master part" axis, and centering the spindle to the "master part" axis.
