【摘要】 提出一种提出了利用平面正交光栅进行几何误差检测的方法。以CINCINNATI750三坐标立式加工中心为对象,建立了包含21项几何误差的数控机床误差分离模型以分离出机床的单向误差。所提出的误差参数分离模型可以推广到多轴数控机床的误差分析上。测量实验表明该误差分离模型是可行的。该方法具有测量精度高,误差参数分离准确的特点。更多还原

【Abstract】 s: A method to measure 21 geometric error of a vertical spindlemachine center is set up by using the cross grid encoder and a model to differentiate 21 error parameters.The model can be used to analyze the error of multiaxis NC machine tools,and is feasible with an experiment.The method has high precision of measurement and differentianting of error parameters.更多还原
