Concentricity
Degree of deviation of the center position in a circular geometry from
the datum circle center (for a planar geometry)
Coaxiality
Degree of deviation of an axis
from the datum axis,
with which it is to be aligned
Squareness
Degree of deviation of a linear or planar geometry from the geometric line or plane perpendicular to the datum line or the datum plane
Circular Runout
Degree of displacement of the object surface from the specified position or to the direction specified at a given position, if an object that should have a surface rotating on the datum axis or an object that should be a circular
plane perpendicular to the datum axis is rotated on the datum axis
Specified direction: Radial direction
Direction that intersects the datum axis and is perpendicular to the datum axis
Specified direction: Radial direction
Direction that intersects the datum axis and is perpendicular to the datum axis
Specified direction: Axial direction Direction parallel to the datum axis
Specified direction: Axial direction Direction parallel to the datum axis
Total Runout
Degree of displacement of the object surface to the specified direction, if an object that should have a cylindrical surface rotating on the datum axis
or an object that should be a circular plane perpendicular
to the datum axis is rotated on the datum axis
Adjustment prior to Measurement
centering
Centering
To prevent measurement errors due to eccentricity, centering must be
performed so that the center of a geometric workpiece is sufficiently aligned with the rotation axis of the measuring instrument.
Leveling
The inclination of a geometric workpiece axis with respect to the rotation axis may cause an elliptic error . Leveling must be performed so that the workpiece axis is sufficiently parallel to the rotation axis.
