复合平面曲线形状公差、方向公差变换算法

Transformation algorithm between the size tolerances and the form tolerances or orientation tolerances on the plane compound contour

根据公差原则的基本思想,以误差控制功能的等效性和公差带边界曲线的连续性为准则,建立了尺寸公差与形状公差及方向公差的变换算法.探讨了线段非圆弧、非直线奇异偏差在算法中的补偿办法,从而为复合平面曲线坐标值测量数据的处理奠定了理论基础.

According to the tolerance principle, by means of the equivalent criterion of the controlling function and the continuity of the tolerance margin, the transformation algorithm between the size tolerances and the form tolerances or orientation tolerances on the contour is advanced. And the modification method is provided for the algorithm in order to compensate the shape deviation from an arc or a straight line Therefore the mathematical basis is established for data processing of the coordinate values measured of the plane compound contour.
