然而，到目前为止圆度和圆柱度的评定仍然没有既符合标准定义又具有快速简洁特性的计算方法。

In this paper, based on the fundamental principle of the three-point method roundness error separation technique, the separation of cylindricity error factors and the reconstruction of the measured cylinder profile was intensively studied, and the methods of evaluating the cylindricity form error were discussed. Furthermore, the separation and reconstruction methods of the cylindricity error proposed in this paper were examined by the experiment.

本文采用三点法圆度误差分离技术的基本原理，重点研究圆柱度误差要素的分离和被测圆柱体形貌重构问题，探讨圆柱度形状误差的评定方法，并对本文所提的圆柱度误差分离及重构方法进行实验验证。

Taking a example for verilying the feasibility and computation precision of the approach,the computation results show that the PSO-based approach is a useful tool for solving such nonlinear optimization problems as cylindricity evaluation with complicated goal function and more parameters. It is superior to that given by the Least Square Method and a little better than or equal to those given by GA-based method and another Minimum Zone Method.

计算结果表明，该方法对于圆柱度误差评定这类具有复杂目标函数和较多参数的非线性优化问题有很好的计算性能，优于最小二乘法；与遗传算法和其它满足最小区域条件计算方法相比，计算精度略优于前者或者与前者相当，能够获得精度较高的结果，而突出优点是简单，易于实现而且计算效率较高。

The evaluation method and algorithm of shape error (roundness, plane straightness, space straightness, cylindricity) were discussed. A new kind of algorithm, namely mesh searching method, which can be used to evaluate the roundness error, plane straightness error, space straightness error and cylindricity error, were put forward. With this algorithm, the shape error can be obtained by transferring the distance formula repeatedly and simple judgment without linearzing the distance formula (from point to point or point to line) and choosing optimal direction and step length.

对形状误差(圆度、平面直线度、空间直线度、圆柱度)的评定方法及算法进行了讨论，提出了一种评价圆度误差、平面直线度误差、空间直线度误差及圆柱度误差的新算法——网格搜索法，该算法不需要对距离公式线性化，也不需要选定优化方向和优化步长，只需重复调用距离公式和简单的判断即可得到符合定义的形状误差。
