摘　　要：为了大幅提升数控机床回转轴的运动精度,从而满足当代数控系统对其高精度的要求,针对机床回转轴的空间几何误差开展了深入研究,提出了可以有效辨识平动轴空间几何误差的便捷方法,并建立了回转轴空间几何误差的辨识模型;针对机床回转轴定位误差的特性,提出了可以实现有效补偿的增量式误差补偿原理,并建立了相应的误差补偿模型。经验证,所提出的回转轴误差辨识法和增量式误差补偿原理不仅理论正确,而且可以大幅地提高机床回转轴的定位精度。In order to promote the movement precision of CNC revolution axis, thereby meet the requirements of modern CNC system for its high precision, the paper develops n - depth study that contraposes space geometric error of CNC revolution axis, proposes a convenient method that can effectively identify the space geometric error of revolution axis, and establishes the translational axis space geometric error identification model; according to the characteristics of CNC revolution axis positioning error, proposes the incremental principle of error compensation to effectively compensate, and establishes the corresponding error compensation model. Verified, the proposed revolution axis error identification method and incremental error compensation principle is correct, and can significantly improve the positioning precision of the machine translation.
