摘要

误差补偿是进一步提高机床精度的重要途径，真实准确的误差模型对最终的误差补偿的效果起着决定性的作用。采用基于多体系统理论的建模方法，对机床拓扑结构、机床的误差元素和坐标系之间的变换矩阵进行充分分析，建立了特定数控机床的综合误差模型，为后期实施对特定机床的实时误差补偿提供了误差计算依据。

Abstract

Error compensation is an important approach to further improve the accuracy of machine tools

the real and accurate error model play a decisive role on the end result of error compensati on.In this paper

Topology structure of machine tool

error elements of machine tool and coordinate transformation matrix are fully analyze dusing the modeling method based on multi-body system theory

and synthesiserror model of a specific machine tool is established.Synthesiserror model provide the error calculation basis for the later real-time error compensation of the specific machine tool.
