Circularity roundness 違い

WebIn GD&T, Circularity describes how close an object should be to a true circle. It is also sometimes called Roundness. Examples of features that might have Circularity controls would be cylinders, spheres, and cones. For moving parts, circularity is often used to help ensure the parts move smoothly and wear evenly. Webdimension is expressed in terms of roundness or circularity. Roundness or circularity can be determined using various instruments such as roundness testing machine, dial gauges, Coordinate Measuring Machines (CMM), gap detectors etc. Among these methods, CMM is widely used in industries due to versatility and ease of operation.

Roundness applies in two dimensions, such as the cross sectional circles along a cylindrical object such as a shaft or a cylindrical roller for a bearing. In geometric dimensioning and tolerancing, control of a cylinder can also include its fidelity to the longitudinal axis, yielding cylindricity.

When a part needs to be both round and straight along its axis, such as a sliding shaft, or a dynamic locating pin, cylindricity is usually called out.
