为节约制造成本，故在设计阶段根据机床结构，合理分配机床产生的几何误差，从而减小相邻部件间误差累积。以TX1600 G镗铣加工中心镗削系统为研究对象，首先结合多体系统理论建立镗削系统空间误差模型并通过该模型推导出误差累积公式；其次在其基础上导入各部件几何误差，通过数值计算与理论分析得到相关部件的误差灵敏度系数，基于此系数提出一种误差分配原则；最终应用遗传算法验证其准确性，该方法也同样适用其它多轴机床误差分配研究。

In order to save the cost of machinery, in the design stage the geometric errors generated by the machine are distributed reasonably in accordance with the machine structure, thus the accumulation of errors between adjacent parts is reduced. Based on the boring systemof TX1600G boring-milling machining center, combining multi-body system theory, model of volumetric errors for the boring system is established and ac-cordingly formulas of cumulative errors are calculated in the first place. Secondly import geometric errors of components onto which you build formulas . With calculating and analyzing to get error sensitivity coefficient of related components , based on this kind of error distribution coefficients are proposed principle. With ap-plication of genetic algorithms to verify the accuracy of the method and this way is applicable to what analy-zes other multi-axis machine error of error distribution in the final.
