Concentricity

The characteristic of two or more forms sharing a common center, axis, or curve, often critical for mechanical parts that rotate.

Overall Flatness

Overall flatness refers to the degree to which a surface conforms to a perfectly flat plane, often specified in manufacturing to ensure parts meet strict flatness criteria.
