New error correction algorithms minimizing residual positional error for a computer integrated error calibration/correction system in computer numerically controlled machine tools

Abstract

Linear displacement accuracy is one of the most important factors determining machine tool performance. Software error correction has been generally used for improving the positional accuracy in computer numerically controlled (CNC) machine tools. In this paper, a set of new correction algorithms has been presented for minimizing residual positional errors in CNC machine tools after correction.
