球形零件坐标测量的数据处理

Data processing method of a spherical workpiece measured in 3-D coordinate

提出一种用坐标法测量球形零件的数据处理方法。该方法消除了在用坐标测量机进行测量时由于被测球心位置与原点距离的不同而引起的评定结果的误差。同时,该方法具有通用性,不但适用于等间隔采点的数据处理,也适用于不等间隔采点的数据处理。

A new data processing method of a spherical workpiece measured in 3-D coordinate is put forward. It eliminates the error caused by the variation of the center coordinate of the spherical workpiece. And not only can this algorithm be applied to the data processing of equal space sampling, but also can be applied to the data processing of unequal space sampling.
