    An analysis of compensation for radial thermal errors of a turning center with a three axis feed system by Zhao Haitao, Guo Jingfeng, Tang Yongbo, Zhang Shuixiang, Yi Xiaoxi

    Published 2025-07-01
    “…Abstract Under normal cutting conditions, the cutting tool tip passes through the spindle axis when it moves along X axis during the whole turning session, however, which is difficult to realize for the turning centers with the conventional two feed axes due to the spindle axis movement caused by the thermal deformation of machine tool structures. Addressing this problem, a novel three-axis feed system is proposed in this paper. …”
