摘　　要：刀具偏置的校正是超精密车削的首要任务,对提高超精密车削效率及精度具有非常重要的意义。传统的刀具偏置校正方法由于缺乏理论指导,存在校正效率低、精度低的缺点,即使利用国外进口软件进行辅助校正,也存在一些问题。对超精密车削中金刚石刀具偏置造成的车削误差展开理论分析,在理论分析的基础上,给出提高刀具偏置校正精度及效率的原则,提出一种新的刀具偏置校正方法——泰曼格林干涉仪在线检测法,并用实验证明其准确性。Correction of tool decentraton is the key task and making important significance for the precision and efficiency of ultra precision cutting. For lacking of theoretical instruction, efficiency and accuracy of the traditional method of tool position correction are not high, even using imported software to help correction, some problems still exist. The cutting errors caused by the position of dia- mond tool were analyzed theoretically. Based on the theoretical analysis, the principle for enhancing the accuracy and efficiency of cor- rection was given. A new tool position correction method, Twyman-Green interferometer online test method, was put forward. Its veracity is verified verified by a practical experiment.
