Glossary
Machine Setup The routine operations performed on a CMM, such as
calibrating probes and selecting measurement units.
Major Radius The greatest possible distance between the outermost
edge of an ellipse and its center.
Manual CMM A Coordinate machine without motor drives on the axes.
Manual Control The user controls the movements of the X, Y, and Z axes
as well as the setup parameters.
Master Sphere Same as Calibration Sphere. An accessory used in
qualifying the probe.
Maximum Traverse The maximum speed along any given machine axis.
Speed
Mean Ambient The mean temperature of the ambient environment
Temperature surrounding a machine. It should be computed from at
least two readings taken at the center of the machine’s
work zone during the interval of the test.
Mean Gage The mean temperature of a gage used for machine
Temperature testing. It should be computed from at least two readings
taken on the gage during the interval of the test.
Mean Scale The mean temperature of a machine scale computed
Temperature from at least two temperature readings taken on the scale
during the test interval.
Mean Temperature The average temperature computed from a number of
temperature measurements at a specified location at
equally spaced time intervals.
Measure A mode where the operator uses the measurement
capabilities and creates a part program saving all the
steps into a learn list file.
Measurement Machine inputs taken on the surface of the work piece
where the location, diameter, etc. are computed.
Measurement Line A line in the machine’s work zone along which measure-
ments are taken.
Measurement Point A point in the machine’s work zone at which machine
coordinates are recorded as part of a measurement.
Measurement The instruction program that tells the computer how to
Software calculate the measurement data.
