摘　　要：根据空间几何理论建立了双转台五轴数控加工空间孔的中心坐标偏置算法模型,利用该模型可以计算出要加工的空间孔随着工作台旋转和摆动后孔口中心在参考坐标系下的坐标,然后利用数控系统的基准偏置功能将参考坐标系的原点偏置到该点,从而可以建立易于空间孔编程的、新的参考坐标系。According to the spatial geometry theory, the modeling of coordinate shift algorithm of spatial hole machined on the five-axis NC machine of dual turntable was established. In the reference coordinate system, the coordinate of the orifice center of the spatial hole rotating and swinging with the turntable can be accurately and rapidly calculated with the aid of the mathematical model, and then the origin of the reference coordinate system can be translated to this point by virtue of the function of datum shift of the numerical control system, the reference coordinate system to be easily programmed can be obtained at last.
