摘要
对于圆柱体的直径尺寸,除了两点尺寸、实际尺寸以及局部实际尺寸外,国家标准还将规定计算尺寸(包括面积直径、周长直径和体积直径)与全局尺寸(包括最小二乘直径、最大内接直径和最小外接直径)。根据这些直径的特点,依据圆柱度截面测量法建立了相应的评定模型。
For cylinder diameters, besides two point size, actual size and local actual size, the National Standard of China also specified computing sizes, which included area diameter, perimeter diameter and volume diameter, and global sizes, which included least square diameter, maximum inscribed diameter and minimum circumscribed diameter. According to the characteristics of these diameters and new GPS regulations, some corresponding evaluation models of these diameters were built using section measuring method of the cylindricity.
