AV&R’s automated profiling systems create high precision elliptical profiles on blades and vanes according to engineering designs. Their adaptive and closed-loop capabilities allow them to reach a ± 37.5 micron tolerance (± 1.5 thousandth of an inch or 0.04 millimeters).

Our automated systems include an inspection system used to perform final profile inspection of the leading and trailing edges. The repeatability of the measurements obtained is: Gage R&R (EV) ≤ 12 % for a tolerance of ±50µm/±.002″ within 4 sigma. Thinning of trailing edges, tri-blend and polishing of the blades, including platforms and fillet radii, can also be executed in these systems.

Whether for high or low pression vanes (HPT & LPT), compressor or fan blades, our adaptive profiling systems achieve the levels of precision required for the newest engine designs.

Advantages of Robotic Profiling

When you automate your blade profiling operations in your plant, you:

  • Improve quality and consistency of your production
  • Increase throughput
  • Reduce abrasive consumption (up to 75%) and therefore costs
  • Improve ergonomics and safety

Main Technologies

  • Leading and trailing edges profiling
  • Trailing edge thinning
  • Foil, platform, and fillet radii polishing
  • Tri-blend operations
  • Chord length feedback
  • Final edge profile feedback

Profiling is a very precise operation. Work with a team of precision experts who will ensure that you meet your specification requirements and offer an automated process that works in your production environment.

Automating the finishing of engine run parts requires an adaptive touch and fast data processing software. AV&R has installed several robotic polishing systems for gas turbine engine repair (MRO) plants. These systems inspect the part as it enters the machine and calculates the work to be done according to its actual shape and the design plans of the original part. The systems work on all sections of engine run blades, removing minimal parent material, critical to the service life of the part.

Since the controlling surface finish part to part is often difficult to achieve, automating this process is the best way to ensure its performance. Our robotic polishing equipment with controlled material removal ensures, for average removals between 25 and 125 µm (between 1 and 5 mils), a consistency of ± 15 µm (± 0.6 mil) from one part to another.

Our innovative systems are a breakthrough in the Maintenance Repair and Overhaul (MRO) industry. Scalable, they currently use the closed-loop and inspection feedback. Our BrainWave software, integrated to the robotic system, gives you control over the execution of the polishing process and allows you to adapt your production in real-time.
