Abstract

The purpose of this study is to estimate the thermal deformations of a CNC lathe based on the temperature rise measured at several lathe parts. In this study, the temperature rise at several points of the lathe and the variation in the distance between the tool and the workpiece obtained by workpiece diameter measurements were determined through turning tests. Based on the obtained results, the thermal deformation between the workpiece and the tool during the turning cycle was estimated using a linear polynomial function that included the coefficients and measured temperature rise. It was confirmed that the proposed method could successfully estimate the thermal deformation of the lathe during the turning operation.
