摘要
探讨一种在统计意义下控制功能等效的变换算法，将生产图样中标注的尺寸公差变换成以参数方程形式描述的形位公差。为应用坐标值电测技术和微机数据处理技术测量与评定滚型轮辋的形位误差提供必要的数学基础。
The paper introduces a transformation method to control statistically equipollent function, which can transform dimen- sional tolerance noted in drawings into form position tolerance in form of parametric equation. Mathematical basis is provided to measure form and position tolerance of roller rim using coordinate value electrometry and microcomputer data processing.
