MetrologyMetrology is the science of measurementDimensional
metrology is that branch of Metrology which deals with measurement
of dimensionsof a part or workpiece (lengths, angles,
etc.)Dimensional measurements at the required level of accuracy are
the essential link between the designers intent and a delivered
