摘要

摘要: 以试切工件的方式研究大型数控机床导轨的直线度误差。用安捷伦激光干涉仪分别测量机床和工件的导轨直线度误差，提出一种混合建模方法。并针对FANUC CNC系统的外部坐标原点偏移功能研制了一种直线度误差实时补偿器。结果表明：通过补偿，直线度误差减少60％以上。不过为保证补偿方案的有效性，机床后续的补偿加工行程需要与误差建模行程一致。

Abstract: Herein, the straightness errors of large CNC machine tool guideways are investigated in the machining of workpieces. Based on the straightness errors of a CNC machine tool and a workpiece measured by an Agilent laser interferometer, a hybrid modeling method is proposed, and a real-time straightness error compensator is developed to aim at the offsetting external coordinate origin function of the FANUC CNC system. An experiment of real-time compensation and machining was conducted on a large gantry CNC machine. The results showed more than 60% of straightness errors were eliminated after compensation. However, the compensation efficiency of this method is guaranteed by the consistence of the subsequent compensation-machining travel and the error modeling travel.
