Cylindricity tolerance zone

WebJul 23, 2024 · Cylindricity is usually measured as circularity measurements in several sections along the workpiece length. The axis of two coaxial cylinders enclosing the cylindricity tolerance zone may be found by taking a point each from first and last measured sections by search methods, typically centered on least square solution. WebMar 26, 2024 · Roundness tolerance zone refers to the tolerance zone between two concentric circles of the same section. As shown in the figure, the extracted circumference should be limited within the tolerance zone between two coplanar concentric circles with a radius difference of t. Why does roundness and cylindricity tolerance occur?
