Model for Surface Topography Prediction in Cylinder Turning

In turning process, the volumetric errors of lathe are incarnated as the displacement between tool and workpiece, and finally mapped to the turning surface. It leads to the ups and downs of the workpiece surface topography. Therefore, the volumetric errors of lathe attach great importance to the turning surface quality. In this paper, a model for surface topography prediction in cylinder turning considering volumetric errors is proposed. It allows the topography and the roughness values of turning cylinder to be predicted. Some simulation experiments are also carried out to analyze the effect of volumetric errors on the quality of turning cylinder in this paper.
