摘要: 为了提高关节式坐标测量机的精度,提出了一种基于聚类的测量姿态优化方法。在数学模型的基础上,通过对测量机的测量姿态信息进行聚类来形成簇,并对簇进行打分和提取,最后根据提取结果对测量姿态进行优化。实验结果表明,测量机精度受姿态影响较大,优化后精度提高了约1倍,为进一步研究奠定了基础。

Abstract: In order to improve the accuracy of articulated arm coordinate measuring machine,the measuring posture optimization based on clustering analysis was proposed.On the basis of the mathematical model,by using systematic cluster analysis,cluster of posture information was constructed,clusters were extracted by scoring method.Measuring posture optimization was finished by result of extraction.The experimental results show that the accuracy of the machine was greatly influenced by the measuring posture,the measuring accuracy was improved by 1 time after the measuring posture optimization.It provides a basis for further research.

Key words: coordinate measuring machine, clustering analysis, posture optimization, mathematical models
