摘要
本文建立了用最小二乘法评定复杂曲面面轮廓度误差的通用数学模型。运用该模型可对任意曲面面轮廓度进行评定,从而将平面度、圆柱度、球度以及任何面轮廓度误差的评定归结在统一的模式中。由于所建立的模型直观、明了,很容易在计算机上实现,因而可在生产实际中普遍推广应用。并对轮廓度误差进行了定性和定量分析,将其分离成形状误差、参数误差和位姿误差,给出了分离公式和误差补偿原则。
In this paper, a general mathematic model of profile error of complex surfaces is proposed with the least squares evaluation. The profile errors of all kinds of surfaces can be evaluated on the basis of this model. This model is very convenient for computer processing ,it can be directly applied in the productive procession. Finally, we deal with error separation and control strategies for quality assurance.
