A measuring arm is a tool used in metrology to perform precise measurements of objects and surfaces. The arm consists of multiple joints that are interconnected, allowing the arm to move in all directions.
Most measuring arms use a combination of optical and tactile sensors to perform measurements. Optical sensors capture the surface of the object being measured through optical scanning, creating a point cloud. Tactile sensors, on the other hand, are capable of touching the surface of the object and measuring its shape and size through touch.
The data captured by the sensors is typically sent to a computer, which then evaluates the measurements and creates an accurate representation of the object in the form of a polygon model. The software that comes with the measuring arm allows the user to monitor the measurements in real-time and verify that the measurements are correct.
Measuring arms are commonly used in manufacturing, quality control, and inspection. They are used, for example, to verify the dimensions of parts and components and ensure that they conform to specified tolerances. They are also used in the creation of 3D models and reverse engineering.
One advantage of measuring arms is their high mobility. By using portable measuring arms, the user can easily bring the device to the location where it is needed, without being tied to a specific location or system. Measuring arms also offer high accuracy and are capable of performing measurements in real-time, allowing for quick and effective measurement.
