Glossary
Nominal
The standard or desired dimension or size of a feature.
The print values for the measurement as opposed to the
measured values.
Nominal Coefficient
An estimate of the coefficient of thermal expansion of a
of Thermal
body. The effective coefficient of a scale and its mount-
Expansion
ing to the mcahine as measured in line with the scale.
Nominal Differential
The difference in thermal expansion between a
Expansion
machine’s scales and a test part
Non-Contact Probes
Probes which do not touch the part being measured,
using vision or laser scanning to measure the part.
Non-Seating Probes
A hard probe that requires force applied by the operator
to maintain its position with respect to a measurement
point.
Normal
A surface, plane or axis that forms a 90 degree angle
with a datum plane or axis.
Normal Vector
The vector that is normal to the surface of the part at a
particular point. The negative of the Approach vector.
Numeric Variable
A value which contains only numbers.
Off-line
The condition in which a device, such as a printer, is not
connected to or communicating with the computer
OIT
Operator Interface Terminal
On-line
A method of creating a part program on the CMM. This
allows the programmer to create a program as the
machine takes measurements.
Operating System
The software that controls the computer. It includes user
commands, input and output routines, and normal
computer operations.
Orientation (Part)
The alignment of an object with respect to a known
reference.
Orientation (Probe)
The process of establishing the center of the probe tip
with respect to an object, feature or other reference.
Origin
The zero point or center of the current coordinate system
and alignment. It is a designated reference point for all
measurements taken of the part.
