The average coordinate measuring machine, also called a CMM, has three axes. The X,Y and Z are arranged in an orthogonal pattern, which is common in three-dimensional machines. The probe, which can be run by a computer program or an operator, moves along these axes to give an accurate measurement of the item that is being scanned.

A coordinate measuring machine (CMM) is a device that measures the geometry of physical objects by sensing discrete points on the surface of the object with a probe. Various types of probes are used in CMMs, including mechanical, optical, laser, and white light.

What Is A Coordinate Measuring Machine? ... How Does The Probe Work? The exact size and position of the tip must be precisely known in advance to establish the “zero” point for all subsequent measurements. That is one of the reasons for using a ruby sphere, since it is a hard substance that does not fluctuate in size due to temperature or ...

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.

A coordinate measuring machine (CMM) works in much the same way as your finger when it traces map coordinates; its three axes form the machine's coordinate system. Instead of a finger, the CMM uses a probe to measure points on a workpiece. Each point on the workpiece is unique to the machine's coordinate system.

byKennedy Smith. It's a bit inaccurate to call new developments in coordinate measuring machine technology "trends."Unlike your favorite suit or dress from 1985--which you'd likely never consider wearing again and have probably given to Goodwill by now--a CMM is not something you just toss out and replace as times (and fashions) change.

Sean -- One important aspect of this sort of measurement is to understand how the CMM is actually going to interpret the instruction, or how the software essentially calculates what you THINK you are asking the machine to do. looking at an average centerline deviation among (6) circles is a different task than creating 2 cylinders and looking ...

The accuracy level of this machine can only be beaten by laser measuring equipment. Another term used for a coordinate measuring machine is coordinate measuring equipment. How does a coordinate measuring machine work? A coordinate measuring machine consists of a probe, upon which either a robot arm with several axles or a multi-axel kinematics ...
