Faro Laser Tracker CMM is a portable, high precision coordinate measurement system. The Laser Tracker CMM is a combination of interferometer based laser optics with state-of-the-art servo control technology to measure the position of a target relative to the tracker. Tracker also contains unique “Absolute ADM” system for enhanced flexibility.
With the polyworks software provided, the real-time positioning information can be used to measure relative distances between points, set up virtual axis, monitor the movement of a part with an accuracy of 8 microns per meter and measurable up to 30 meters with 3d cad model comparison.
Ever heard this term? If not then get reading as we tell you what this instrument is all about and how it assists in the industrial needs. The laser tracker is nothing but an instrument which is used to very accurately measure objects that are large in size and beyond the normal optical range. The optical position of these large objects needs to be determined and Laser trackers do exactly the same. They measure their position against the optical trackers. The normal accuracy of laser trackers is usually 0.025 m.
Laser trackers are most extensively used in automation and aerospace industry. These laser trackers comprise of very complex components, namely angular encoders and interferometers. Laser trackers are nothing but robots that are used as measuring devices. As any other robot, they are also subject to certain sensitivity from the environment. Laser trackers are known to be very sensitive to thermal power effects. Once the laser tracker is initialized it needs to reach a certain temperature level to get activated, therefore initial warm-up time is crucial in initializing tracker.
There are many industries, namely the automotive industry and the aerospace Industry as mentioned earlier, that make use of huge multidimensional objects and therefore they need a device that can help them measure these magnanimous components. This very feature helps these devices to measure in the most accurate way. The laser tracker device was invented back in 1980 and as its name suggests, it makes use of a laser beam to measure the target that is held in contact with an object.
The measuring capacity of the laser tracker depends from device to device it is generally seen that the tracker can measure objects up to the range of 60.
Trackers are known to have a single measuring capability of up to 0.0025 meters. The trackers make use of just one operator and can collect data at very high speed. This intern can make manufacturing methods offer a very high level of performance which is possible due to this very feature of the laser trackers.
While there are many instruments available that can be used for such measurement purposes, each one of these instruments is specifically designed for only certain types of applications. The CMM that also stands for coordinate measuring machines, can carry out multiple measurements at a very high speed and with complete accuracy. But the flipside to this measuring device is that they are immovable and they have a very limited range of measurement. They are also a bit on the higher side as far as cost is concerned.
These devices are more popularly used for inspection of small to medium-sized mechanical components, where there is more emphasis on high speed and accurate performance.This is the reason why laser trackers are more in demand when it comes to large size components and has taken over these earlier systems of measurement.
While it is not such a complicated process one needs to understand that all laser tracker takes into consideration two angles and the distance between itself and the object to be measured. There is something called a retroreflective target which is held against the object that is to be measured. A laser beam is sent to this retroreflective target and the light that is reflected away from the target reenters the tracker at the very position from where it had left. The most common of these is SMR which stands for a spherical amounted retroreflector. Once the light reenters the tracker, a part of this light reaches the meter at a distance and this meter measures the distance between the tracker and the SMR. The distance meter as mentioned earlier can either be an interferometer or something called an absolute distance meter.
The absolute distance measurement meters have been in practice for quite some time now. In the last 10 to 15 years however, this system has undergone transformational change with a lot of improving its design and quality, which enables it to be more precise. They offer a high amount of accuracy in comparison to other counterparts. That is interferometer the ADM very precisely points the beam towards the target and shoots accurately. The ADM also measures the desired distance in an automatic way, even if for some reason the beam is broken and does not reach its desired position.
