Glossary
Abort To stop (cancel) an impending action or command.
Absolute Value A value which disregards the plus or minus signs of
numbers and adds their values together.
Acceleration The rate of change of velocity.

known standard. The quantitative measure of the degree
of comformance to recognized standards of measure-
ment.
Active Plane The plane in which you are currently working.
Actual Probe The true size of the probe diameter.
Diameter
Actual Value The measured value of a feature.
Air Bearings An accurate form of support for the moving axis ele-
ments of the machine. Air is forced by pressure through
the space between the bearing pad and the axis way
surface creating a film of air which permits movement of
the machine’s members with almost no friction.
Alignment The procedure of relating the XYZ coordinates of a part
to the coordinates of the machine, compensating for the
fact that the part is not perfectly square to the machine’s
table. It shows the CMM where the workpiece lies.
Angle The degree of difference between two features eventu-
ally meeting in a point.
Angle of Lines A measurement routine that computes an angular
distance between 2 line elements.
Angle of Planes A measurement routine which computes an angular
distance between 2 plane elements.
Angularity The measured angle between two features.
A.N.S.I. Y14.5 An American National Standards Institute standard for
dimensioning of drawings.
Append To add to an existing part program.
Applications Software that provides the computer with instructions
Software for a specific task, such as inspecting a part.
