摘要
圆柱度是回转体零件的最典型技术指标,如何实现圆柱度误差的快速、准确评定对回转体零件至关重要。这里基于“小偏差”假设建立了最小区域圆柱度误差评定模型,提出采用原始对偶内点法对所建立的圆柱度误差模型进行求解。为了验证该算法的有效性,使用文献中的测量数据和海克斯康坐标测量机的实测数据分别对算法进行实验,实验结果表明原始对偶内点法在评定精度、评定效率和评定结果重复性等方面均优于现行的一些算法,为实现圆柱度误差的数字化计量提供了一种稳定可靠的方法。
Cylindricity is the most typical technical index of slewing body parts.It is important for slewing body parts to achieve accurate evaluation of cylindricity error rapidly.A mathematical model of the minimum zone cylindricity error evaluation was established based on the assumption of“small deflection”.The primal-dual interior point method was proposed to solve the established model.In order to verify the proposed method,the cylindricity error of the measurement data from the references and Hexagon coordinate measuring machine were computed and were compared with the results by the other methods.The experiment results shown that the evaluation accuracy,evaluation efficiency and evaluation results repeatability by using the primaldual interior point method were superior to other algorithms,which provided a stable and reliable method for digital measurement of cylindricality error.
