形状和位置误差简称形位误差。
形位误差评定 Geometric Error Evaluation
The author proposed a new rotating coordinates convex hull algorithm, and using it in assessing roundness to reduce the computation.3. A system for evaluating form and position error is established, which including part measurement, error separation and data evaluation.
3.构建了形位误差评定系统结构,将其分为测量、误差分离和数据评定三个部分,并详细构建了数据评定部分的功能模块。
