Glossary
Level
A part feature specified as a reference that is used during
an alignment.
Length
A measurement routine that determines a measured
perpendicular distance between a point and a line.
Lift
The thickness of the air film in an air bearing.
Limit Tolerancing
A method of tolerancing that specifies the maximum and
minimum size of a feature.
Line
A geometric element that consists of two points and has
direction from one point to the other point.
Linear Coordinates
A method of locating a point by its distance from zero
point along any of the three axes (X,Y,Z). Also called
Cartesian Coordinates.
Linear Accuracy
A non-specific term sometimes used in reference to
positional accuracy or to axial length accuracy.
Linear Displacement
The difference between the true displacement of the
Acuracy
probe along a straight line and that indicated by the
machine measuring system.
List
To display a part program on the CRT.
LLF
The learned list file or the part program.
Lobing
A systematic error in the measuring accuracy of probing
systems such that a measured value depends on the
displacement direction of the probe tip.
Login
The procedure performed to boot a computer. It usually
involves typing a password.
Machine Axes
The X, Y, and Z axes built into the CMM. Each type of
machine (vertical, horizontal, etc.) has different axes
arrangements.
Machine
X, Y, and Z values that have not been altered by part
Coordinates
alignment compensation.
Machine Hysteresis
The hysteresis of the machine system when subjected to
loads.
Machine Named
The two axes of the machine’s working plane. In the XY
Axes
working plane, X is the first-named axis and Y is the
second-named axis. The Unnamed Axis is the axis not
named in the working plane, in this case Z.
