When a three-dimensional shape is machined by NC machine tool, motion errors occur around the motion direction changing points of the translational axis. This has a significant influence on a quality of machined surfaces. Therefore, much research on the influence of motion errors around the motion direction changing points of the feed drive system on a machined surface has been conducted to improve the quality of machined surfaces by NC machine tool. Among the motion errors that occur around the motion direction changing points of the translational axis, quadrant glitches with a stick-slip motion have a particularly large influence on the machined surface, and research on compensation methods continues to be reported. However, the transcriptional characteristics of quadrant glitches of the translational axis for machine tools have not been investigated adequately. In this study, the transcriptional characteristics of quadrant glitches of the translational axis on a machined surface were investigated. In addition, the influences of various factors on the transcriptional characteristics of quadrant glitches on a machined surface were investigated using a proposed equation and actual machining tests.
