Abstract

Numerical error compensation is a cost-effective way to further improve the accuracy of high precision CNC machine tools. This paper discusses the major techniques for numerical error compensation on high precision machine tools. First, the high accuracy 2D holographic scale system and the dedicated measurement software are introduced. Then, the mathematical modeling of repeatable machine tool errors and the synthesis of volumetric error model are presented, followed by a description on the procedure of NC code modification. Error compensation experiments have been performed on a ballscrew driven machine tool and a linear driven machine tool. The experimental results show that numerical error compensation is generally effective on machine tools with both drive systems, while the linear driver system provides better dynamic performance for further improvement when the control precision is increased.
