Glossary
CMM Coordinate Measuring Machine. A machine that per-
forms physical movements necessary to inspect a part in
three dimensions.
CMS Coordinate Mesuring System. A system for part
inspection that includes a coordinate measuring
machine, controller, system computer and software.
Computer Assist The use of a computer to process raw data into meaning-
ful measurements. Probe movements are directed
manually by the operator.
Concentricity The location of a feature’s axis in relation to another
axis. A measurement routine that computes the TIR
(Total Indicator Reading) between two circle centers.
Cone A three dimensional space formed by a base and angled
sides running from the base to the tip or apex. A mini-
mum of six points are required to define a cone.
Contact Probes Probes which must touch the part in order to make a
measurement. They can be either rigid or electronic.
Contact Velocity The speed of the probe as it actually takes a measure-
ment and touches the part.
Coordinate The X, Y, and Z values that identify the location of a
point in space.
Coordinate System A method of locating a point in space by assigning it a
value according to its distance from a reference. Two
types are Cartesian coordinates and polar coordinates.
Cosine Error The measurement error in the motion direction caused
by angular misalignment between the measuring system
and the part being measured.
CPU Central Processing Unit. The ‘brain’ of the computer.
CRT Cathode Ray Tube. Another name for the computer
screen or video display.
Cursor An underline mark, arrow or rectangle that appears on
the computer screen and marks the position of the next
character to be entered.
Cylinder A circular three dimensional space. A minimum of five
points are required to define a cylinder.
