3D-coordinate measuring instruments
3D coordinate measuring machine is based on the principle of coordinate measuring technology and includes a measuring system suitable for measuring spatial coordinates. It consists of a measuring head system (switching or measuring sensor) whose measuring range is extended by a traversing or positioning system with incremental displacement or angle sensors.

3D coordinate measuring machines are high-precision instruments that are used in various fields such as industry, medicine and research. They enable the precise determination of three-dimensional coordinates and therefore the exact measurement and inspection of objects. A 3D coordinate measuring machine usually consists of a stable base plate on which a movable measuring arm or a measuring bridge is located. A measuring probe is attached to this arm or bridge, which can determine the position of a point in space with high accuracy. This measuring probe can use different technologies, such as optical sensors, lasers or styli. The functionality of a 3D coordinate measuring machine is based on the principle of triangulation. The position of the measuring point is determined by measuring the transit time of light pulses. The measuring probe emits a pulse which is then reflected by a reflector or a surface of the object to be measured. The distance between the probe and the object can be calculated based on the transit time of the pulse. The rotation and movement options of the measuring arm or bridge can then be used to determine the coordinates of the measuring point in space. The main advantages of 3D coordinate measuring machines are their high precision and accuracy. They enable measurements in the micrometer range and are therefore particularly suitable for applications where absolute precision is required, such as in the quality control of components or the measurement of workpieces. In addition, 3D coordinate measuring machines also offer a high degree of flexibility. They can be used for measuring both small objects and large components. They also enable the measurement of complex geometric shapes, such as free-form surfaces or threads. 3D coordinate measuring machines can be used for a wide range of applications. They are used in the automotive industry to check components, in medicine to measure implants or prostheses and in the aerospace industry for quality assurance of aircraft components. Overall, 3D coordinate measuring machines help to improve the quality and precision of products. They enable the precise inspection of components and thus ensure greater product safety and reliability. They also support research and development by providing precise measurements that contribute to the further development of products and technologies.
What are 3D coordinate measuring machines and how do they work?
3D coordinate measuring machines are advanced measuring instruments that are used to capture the exact three-dimensional coordinates of objects. They are often used in manufacturing, quality assurance, engineering and other areas where precise measurements are required.
The functionality of a 3D coordinate measuring machine is usually based on a combination of technologies such as optical metrology, laser scanning, tactile metrology or a combination of both. Here are some common types of 3D coordinate measuring machines:
1. Tactile measuring devices: These devices use mechanical probes or probes that come into contact with the object to be measured. They use precise measuring techniques to record the coordinates of each point and create a three-dimensional model.
2. Optical measuring devices: These use optical sensors to scan the surface of the object and record the coordinates. They use techniques such as white light interferometry, fringe projection or stereo image processing to carry out highly accurate measurements.
3. Laser scanner: These devices project a laser beam onto the surface of the object and measure the reflection of the beam to determine the coordinates. They can detect large objects or complex geometries quickly and precisely.
The captured data is usually transferred to software that converts the point clouds into a digital 3D model. This model can then be analyzed, measured and compared with other models in order to detect deviations or check quality standards.
Overall, 3D coordinate measuring machines enable precise and efficient acquisition of geometric information from objects, which is of great importance in many industries.
