摘　　要：提出一种基于混沌和蚁群算法计算圆度误差的方法,它将混沌搜索与蚁群算法相结合,在蚁群搜索完成后,利用混沌进行搜索,以提高搜索精度.简要地介绍了混沌和蚁群算法的基本原理,详细地描述了蚁群算法和混沌解决圆度误差评价问题的步骤.最后给出实验结果.仿真实验结果表明,这种方法可以有效、正确地评价圆度误差,克服了利用最小二乘法评价圆度误差的局部收敛问题.A new method for calculating the roundness error based on chaos and ant colony algorithm has been proposed. In this method, the chaotic search algorithm and the ant colony algorithm are used together. After the ant search, the chaotic search is used to improve the precision. The basic principle of chaos and ant colony algorithm is concisely introduced in this paper; a detailed step for calculating the roundness error based on chaos and ant colony algorithm is described. Finally experiment results are given. These results show that this method in this paper can correctly and effectively evaluate roundness error. The method overcomes the local convergence in evaluation of roundness error based on least square method （LSM）.
