*A coordinate measuring machine (CMM) is a device for measuring the physical geometrical characteristics of an object.

*This machine may be manually controlled by an operator (or) it may be computer controlled. *Measurements are defined by a probe attached to the third moving axis of this machine.

*Coordinate measuring machines (CMMs) are mechanical systems designed to move a measuring probe to determine coordinates of points on a workpiece surface. They provide precise measurements of objects for design, testing, assessment, profiling, and reverse engineering of parts.

*Machines are available in a wide range of sizes and designs. They use a variety of different interfaces and modeling software.
