3239 A Developmental Study on Two Dimensional Laser Scale System for High Precision Machine Tool System

Abstract

A system for measurement and error compensation of high precision machine tools is being developed. This system involves a sub-nanometer precision, holographic, two-dimensional laser scale, as well as custom developed software. Currently the software allows for measurements to be taken and recorded, with that data being used to develop error maps and compensated NC code. The software will also include the ability to dynamically update the error map. Experiments have been carried out to verify the usefulness of this system, and results show significant error reductions.
