ABSTRACT:
A work locating system having temperature and other compensation capabilities wherein the work member is mounted for controlled movement with respect to the work tool. Two sets of two laser interferometers are utilized to generate distance measuring light beams such that the beams of each set are coaxial and the beams of the respective sets are orthogonal and intersect at the work tool reference axis to thereby instantaneously and continuously determine the location of four reference points on the work member and compensate for all expansions or contractions of the work member or changes in the laser measuring system during the programmed work operation.
