moving members.
Buffer A storage (holding) area in a computer for measurement
data.

Calibrate To adjust a measuring instrument or inspect it for
accuracy.
Calibration Sphere An accessory used in qualifying the probe. A master

Cartesian Feature output expressed as X, Y, and Z.
Cartesian A system used to describe points in space in terms of X,
Coordinates Y, and Z axes. The axes are perpendicular to each other.
The points are expressed in relation to some fixed origin
(zero point).
Cartesian Coordinate A measuring system that uses three independent,
Measuring System mutually perpendicular, axes to form a grid. The
coordinates of a point are measured as distances from
each of these axes.
Centroid The weighted center of all points that make up an
element.

Circle A geometric element defined by a minimum of three
points equidistant from a centerpoint. A measurement
routine used to compute the diameter and location of a
bored hole or a cylinder.
Circle-Circle A measurement routine which computes the shortest
Distance two-dimensional distance (working plane) between 2
circle center points.
Circularity The condition of a circle as it lies in a tolerance zone
formed by two concentric circles. Also called roundness.
