摘　　要：本文提出了多轴机床空间误差的一般模型，该模型把刀具相对工件的误差表达为机床各相连组件之间误差的线性组合。适用于任意结构的机床以及坐标测量机和测量仪器。利用这个模型进行软件误差补偿，在不提高成本的情况下。A general volumetric error model is presented. It can be applied to multi axis machine, coordinate measuring machine and measuring instrument of arbitrary serial configuration.The errors of the tool with respect to the workpiece are expressed as a linear combination of the errors in the location of coordinate frames attached to succeeding components of the machine. Using this model, the error of machine can be compensated by software method.The accuracy of machine can be improved without great expenses.
