Laser Tracking Equipment 

Does your line of business frequently involve performing dimensional inspections? This could be on car wheels during vehicle manufacturing, or you might be in a garage that uses such equipment to realign misaligned wheels. Or perhaps your business works on large machinery or other equipment. Whatever the case, you’ll want to invest in laser tracking equipment to make the whole job easier. 

At ETG, we’re one of the top manufacturing companies, specialising in producing engineering solutions to suit all business requirements. Among other things, we produce bespoke laser tracking machines tailored to every scenario. We produce these machines alongside other inspection and automation technologies. 

Ours is a lean process that offsets activities, processes, and materials that add zero value to the product. This, in turn, saves you money while ensuring speed, quality, and accuracy. And with future-proofed laser tracking equipment, you can be confident of many years of reliable use. To get started, call us on +44 2476 428 500. 

What Is Laser Tracking Equipment? 

Laser tracking machines are often referred to as portable coordinate measuring machines. A laser tracker is a piece of technology built with one purpose – dimensional inspection. This can be of large equipment, such as huge assemblies or individual pieces of equipment. Laser trackers are often used to check the alignment of wheels, too, during the vehicle manufacturing process. 

Taking such precise measurements of large equipment or even checking wheel alignment can be a tedious undertaking. And it can be very easy for human error to slip in, leading to issues developing. Laser tracking equipment eliminates this problem, taking pinpoint measurements that are easily repeatable of machinery or wheel alignment. As a result, even the most minor misalignment can be spotted and remedied quickly. 

Laser trackers can be implemented indoors and outdoors and work so that no dismantling is necessary. This makes laser trackers an excellent time-saving tool. 

Typically, laser tracking equipment can be used in conjunction with computer software to provide incredibly fast and accurate feedback in real-time. That’s why such devices are favoured in manufacturing environments, such as car manufacturers for checking components like wheels. 

In fact, there is a wide range of common applications for laser tracking equipment, besides just checking wheels, including: 

  • Machining 
  • Design 
  • Assembly 
  • Inspection 
  • Installation 
  • Maintenance 
  • Repair 
  • Manufacturing 

They can be used to check a whole array of things, from wheels to turbines, compressors, CNC machines, pumps, etc. Such things are usually found in engineering setups and must be correctly calibrated to mitigate safety risks and downtime while maintaining operational efficiency. 

Furthermore, laser tracking equipment is also ideally suited to machining (as mentioned above), providing real-time feedback on critical geometry controls. Laser tracking equipment easily surpasses all other methods for precision, regardless of the circumstances, able to comfortably handle cylindricity, circularity, parallelism, and planarity. 

But how does laser tracking equipment work? First, they take precise large-volume measurements of parts, tooling, and assemblies. They have a large working radial volume and support accuracies up to 0.001in. They measure two angles and a distance, and they do this by targeting a retro-reflective target with a laser. 

This target is held in place against whatever is being measured, and as the laser is fired, the light reflects back, with the path of the laser being retraced. A portion of this returned light re-enters the measurement tracker at the precise position it left, and as it re-enters, some of it enters something called a distance meter. 

The distance meter is responsible for measuring the distance from the Spherically Mounted Retroreflector (SMR) to the tracker, and one of the two types of distance meters may exist – interferometer and ADM or absolute distance meter. 

ADM measures the distance to the target automatically and offers the user the benefit of a much simpler ‘point and shoot’ system. The process works regardless of whether the beam to the target has been broken and involves infrared light from a semiconductor laser reflecting off the SMR and re-entering the tracker. At this point, the onboard circuitry analyses the signal that determines the time of flight. 

Once this has been determined, whatever value has been generated is multiplied by the speed of light in air, calculating the distance from the tracker to the SMR. 

Conversely, with distance measurement, this can be either absolute or incremental. An incremental measurement is produced when an interferometer and a frequency-stabilised helium-neon laser are used. An incremental movement moves a distance based on your current position. With an absolute measurement, it moves to a coordinate based on your zero point. 

Distance measurement was once considered the go-to standard, though ADM is rapidly catching up. 

Here at ETG, we can manufacture laser tracking machines that perform both functions. We welcome a discussion to learn more about your requirements.

Benefits of Laser Tracking 

If you’re considering investing in laser tracking equipment, whether to check wheel alignments, inspect large machine assemblies, repair work, etc., we’ve got you covered. If you’re still on the fence, however, you may wish to consider the advantages of investing in laser trackers. Benefits include: 

  • Versatile Mount 
  • Small, Lightweight Design 
  • Easy to Use 
  • Continuous Point Measurement 
  • Super-Fast Single Point Measuring 
  • Highest Precision and Accuracy 

First, it’s worth noting that laser tracking equipment is usually very light and portable, making it easy to transport out into the field. Second, with the right mount, a laser tracker can be easily positioned sideways, upside down, or directly on the part being measured, making any job that much easier. 

Laser tracking equipment is also very simple to use, requiring only a single operator, if necessary, though a two-man crew is recommended for better time management. Laser trackers can measure points continuously through continuous point measurement, which enables complete tracking of critical areas, including shrinkage, moving machinery, and thermal growth. No human interaction is needed. 

Another benefit of laser tracking equipment is that it can be used to record 3-axis measurements in a fraction of a second. This is made possible courtesy of super-fast single-point measuring. You can also add extra accessories to facilitate the quick collection of data points in mass. 

Lastly, no other traditional technique outside of laboratory environments is as accurate as laser tracking equipment. Laser trackers sport real-world tolerance of one-thousandth of an inch and are by far the most accurate option, especially when compared to optical measurements, often prone to measurement variation and human error. 

So, whether you’re fixing or installing wheels on a new car or doing an installation job, laser trackers make the process easier.
