Coordinate-measuring Machines

Coordinate-measuring Machines

Coordinate-measuring machines (CMMs) are precision measurement devices that are used to measure the physical geometrical characteristics of an object. These machines use a probe that is moved along three axes to measure the X, Y, and Z coordinates of a point on the surface of the object being measured. The probe is typically a touch-trigger probe that makes contact with the surface of the object at a predetermined point, and then sends a signal to the machine's computer, which records the coordinates of the point. CMMs are used in a wide range of industries, including aerospace, automotive, medical, and manufacturing. They are particularly useful in industries where precision is critical, such as in the production of aircraft parts, where even the slightest deviation from specifications can have catastrophic consequences. There are several different types of CMMs, including bridge-type, cantilever-type, and gantry-type machines. Bridge-type machines are the most common and are typically used for measuring small to medium-sized objects. Cantilever-type machines are used for larger objects, while gantry-type machines are used for the largest objects. One of the key advantages of CMMs is their ability to measure complex shapes and contours with a high degree of accuracy. They are also able to measure multiple points simultaneously, which makes them much faster than traditional measurement methods. Additionally, CMMs can be programmed to automatically perform measurements, which reduces the risk of human error. Overall, coordinate-measuring machines are an essential tool for industries that require precise measurements of physical objects. They are able to measure complex shapes and contours with a high degree of accuracy, and can be programmed to perform measurements automatically. As technology continues to advance, it is likely that CMMs will become even more precise and efficient in the years to come.
