Laser correction of geometric errors of multi-axis programmed-controlled systems

A method of laser correction of the geometric errors of multi-axis programmed control equipment, such as machine tools and plate measuring engines, as well as a traditional standardized method of correction of geometric errors with respect to individual coordinate axes and a method of correction of the total three-dimensional error are considered. It is shown that the new method is effective, in that it enables a 10-fold or greater reduction in the geometric errors of these types of machines, including machines equipped with long-path coordinate axes (greater than 18 m). Optimal control of the distribution of errors assuring their minimal values in the maximal zone of the workspace is proposed.
