摘要
圆度误差的准确评定对轴和孔类零件的质量评判有很重要的意义。针对目前常用的圆度误差评定方法存在原理误差或模型误差的问题,提出一种完全符合最小包容区域法定义的圆度误差评定方法。该方法将区域搜索算法和圆度误差最小包容区域法评定的几何结构相结合,利用区域搜索算法确定准圆心,再根据准圆心位置和几何结构,对其进行判断和调整,最终找到准确的最小包容区域圆心,并给出最小包容区域圆度误差的精确解。构造多组仿真数据,利用此方法的评定结果与预设值相比较,证明了该方法的有效性和正确性;并利用该方法对其他文献中的数据进行评定与比较,数据处理的结果进一步显示了该方法的评定结果精确可靠,稳定性好,且效率高,可以有效地克服现有圆度误差评定方法难以找到准确最小包容区域圆心的缺陷。
It is very important for the quality evaluation of shaft and hole parts to evaluate the roundness error accurately.Aiming at the problems of principle error or model error in the commonly used roundness error evaluation methods,a roundness error evaluation method which fully meets the definition of the minimum zone method is proposed.This method is an evaluation method that combines the area searching algorithm with the geometrical structure evaluated by the minimum zone method of roundness error.The quasi-central center are determined by the area searching algorithm.Then it is judged and adjusted according to the quasi-central center and geometrical structure.Finally,it can accurately find the center of the minimum zone circle.So the exact roundness error of the minimum zone method can be obtained.Several sets of simulation data are constructed.And the validity and correctness of this method are proved by comparing the evaluation results of this method with the preset values.After evaluating other literatures’data and comparing,the results further show that the evaluation results of this method are accurate,reliable,stable and efficient.It can effectively overcome the shortcomings of current roundness error evaluation methods.
