Computer-assisted metrology and measurement (CMM) systems have been around for more than three decades now. With advances in technology and miniaturization, these systems have found their way into manufacturing and production processes. A CMM is similar to a coordinate-measuring machine (CMM) but differs in that a CMM can both measure and analyze a given object. It can be equipped with a variety of sensors and has the capability of measuring objects that range from a few microns to several feet in size. In this article, we will take a look at the application field and working principle of CMM.

CMM systems are valuable in many industries and application fields. They are used in quality control, where large quantities of parts must be accurately measured and analyzed for quality assurance purposes. CMM systems can also be used for reverse engineering, medical device prototyping, 3D modeling, drilling and manufacturing processes, and metrology analysis. In addition, CMM systems are used for assembling aircrafts and automobiles, wherein both measurements and inspections are standard procedures.

The working principle of CMM systems is relatively simple. A CMM system consists of a bed in which a 3-dimensional object is placed. Sensors and probes attached to the bed measure the object’s dimensions using a variety of techniques such as touch-triggering (where a probe interacts with the object to measure its features), scanning (where a laser or other type of light is used for scanning the object), and vision systems (where cameras are used to measure object features).

The probes are usually calibrated to measure a specific feature such as a hole, slot, or edge, and the data collected by the probes is then sent to a computer for further processing. The computer takes the data and converts it into a coordinate system which can then be used to calculate the size and position of the object. Once the data is collected and processed, the user can check for accuracy or errors. If any errors are found, the system can be adjusted to obtain a more accurate result.

CMM systems are suitable for measuring a wide variety of objects and they can be used in a variety of industries. They are widely used for reverse engineering and 3D modeling, where precise measurements are required. In manufacturing, CMM systems are used to measure objects for processes such as machining, drilling, and assembly. CMM systems can also be used for metrology analysis and quality control to ensure that parts meet the required specifications.

In conclusion, CMM systems are invaluable tools in many industries. They are used for a variety of applications such as reverse engineering, 3D modeling, manufacturing, metrology analysis, and quality control. These systems use a variety of sensors and probes to measure and analyze an object in a 3-dimensional space. The data collected by the probes is then sent to a computer for further processing and the user can check for accuracy and errors.
