FARO Arm & PolyWorks for Precise Part Alignment

Accurate Alignment in Industrial Assembly

Accurate alignment between mechanical components is critical in industrial manufacturing and maintenance. In applications such as gearbox and motor assemblies, even small alignment errors can lead to vibration, premature wear, reduced efficiency, and costly downtime.

To achieve precise alignment quickly and efficiently, many industries use the combination of a FARO portable measurement arm and PolyWorks inspection software.

Aligning Components to CAD Data

The FARO arm is a portable coordinate measuring machine (CMM) designed for high-accuracy measurements directly on the shop floor. When paired with PolyWorks, it becomes a powerful alignment solution capable of measuring component positions in real time and guiding technicians during assembly adjustments.

One of the key advantages of this combination is the ability to align parts directly to their nominal CAD positions. During a gearbox and motor installation, the FARO arm captures critical features such as mounting holes, shaft centers, flanges, and reference surfaces. PolyWorks then compares these measurements against the design model or alignment targets, instantly displaying positional deviations.

This real-time feedback allows technicians to adjust components immediately during installation. Instead of relying on manual measurement methods or trial-and-error alignment, operators can see exactly how far a component is out of position and make corrections with high precision. This significantly reduces setup time and improves assembly accuracy.

Portable Measurement on the Shop Floor

The portability of the FARO arm is especially valuable in industrial environments. Large assemblies such as motors, gearboxes, pumps, turbines, and production equipment are often difficult to move to dedicated inspection areas. With the FARO arm, measurements can be performed directly on-site without interrupting the workflow. This minimizes downtime and allows alignment tasks to be completed more efficiently.

PolyWorks enhances the process by providing advanced visualization and alignment tools. Operators can view live deviation maps, coordinate positions, and alignment values while measurements are being taken. The software also supports best-fit alignment calculations and datum-based positioning, making it suitable for both simple and highly complex assemblies.

Improving Shaft and Coupling Alignment

Another major benefit is improved accuracy in shaft and coupling alignment. Misalignment between a motor and gearbox can create excessive loads on bearings and couplings, leading to increased maintenance costs and reduced equipment lifespan. By using the FARO arm and PolyWorks together, technicians can verify positional accuracy within tight tolerances, helping ensure smooth and reliable machine operation.

The system also improves repeatability and documentation. PolyWorks automatically records measurement data and generates detailed alignment reports, including deviation values, graphical comparisons, and inspection results. This creates a traceable record of the alignment process, which is particularly valuable in industries with strict quality and maintenance requirements.

Flexible Across Industrial Applications

In addition to mechanical assemblies, the FARO arm and PolyWorks combination is widely used for fixture alignment, machine installation, aerospace assemblies, heavy equipment manufacturing, and industrial maintenance applications. The flexibility of the system allows it to adapt to a wide range of alignment tasks while maintaining high measurement accuracy.

Cost efficiency is another important advantage. Faster alignment procedures reduce machine downtime and labor costs, while improved accuracy helps prevent future mechanical failures and expensive repairs. By identifying alignment issues early, manufacturers and maintenance teams can avoid production interruptions and improve long-term equipment reliability.

Conclusion

As industrial systems become more advanced and tolerances continue to tighten, precise alignment solutions are becoming increasingly important. The combination of the FARO arm and PolyWorks provides manufacturers and maintenance teams with a fast, accurate, and practical solution for aligning critical components such as gearboxes and motors with confidence.
