坐标轴
This finding is verified by the experiment.5. A method of measuring and identifying the lathe motion error is proposed, where the coordinate system is related with processing system and machining state, the identification of geometrical errors and motion errors of the machine tool is accomplished by calibrating the error distribution in the corresponding coordinate axes.
5．探讨了机床运动误差的测量与辨识方法，通过标定工艺系统坐标系相关坐标轴上的误差分布实现了对机床几何误差与运动误差的辨识，简化了对众多误差源的处理，较好地解决了加工空间法标定难和综合法数学表达相对复杂的问题，为具体机床加工精度的预测奠定了基础。
