Our robotic automated visual inspection solutions detect surface defects (nicks, scratches, tooling marks…), the presence or absence of elements, the position of features, etc. While some of these solutions are marketable today, others are still in development by our team of experts.
AV&R currently offers inspection systems that recognize 2D characters and ensure that a feature is positioned correctly or in the required dimension. This type of inspection may include surface profile analysis and the software tools use precision calibration and morphological analysis.
In addition, we have designed systems that can validate part assembly, through their ability to archive images of a given assembly or specific components. These systems can also perform optical character recognition to validate that a specific component is present and compliant.
Always aiming to reach new goals, we have produced robotic inspection systems that use machine vision, algorithms fully adapted by our engineers, and robots that mimic human movements to perform a fully automated inspection of parts. These systems detect any defect a conscientious human eye can see, such as handling defects (dents, nicks, scratches, pits, etc.) or process defects (polishing marks, grinder marks, inadequate shot peening, coating chips, etc.). These systems are designed to aid an inspector. To learn more, see our Tomorrow section.
Examples of projects we have completed include:
- Visual inspection for surface defects on blades, variable vanes, blisks / IBRs for gas turbines
- Visual inspection for surface defects on knee and hip orthopaedics implants
- Validation of cooling hole presence
- Optical Character Recognition (OCR)
- 2D matrix dot marking reading
- Visual validation of complete aircraft engine assembly
- Elimination of human subjectivity related to visual inspection
- 100% complete inspection
- Process quality feedback
- Elimination of the risk of shipping a part that does not comply
At AV&R, we have a team of experts dedicated to automated visual inspection that will help you meet your quality control challenges.
Visual inspection is the inspection of the surface of an object to detect defects such as nicks, scratches, tool marks, etc. Critical in quality control, this type of inspection comprises a lot of challenges. Our team of experts in automated visual inspection works with major clients to develop a robust industrial solution. With these partnerships, we adapt and test our equipment in production environments in order to bring them to maturity.
Ultimately, this solution will replace the arduous task of inspectors who must inspect the surface of parts. Whether for aircraft engine blades, medical implants or even watch crystals, this task remains a difficult process to maintain on the side of manufacturers. The biggest challenge currently facing the implementation of such solutions is the difficulty of differentiating the acceptable defect from something that may be only a superficial artifact.
AV&R has chosen the path to work within partnerships to launch this type of system for a simple reason: our system detects all surface defects. It can qualify them to decide whether it is an acceptable defect or not, based on the specifications provided by the manufacturer. Unfortunately, the specifications provided is not detailed enough for a robotic system and there is work in the industry to revamp visual inspection criteria. Over time, we have found that each of our clients factories approaches the issue and defines these criteria differently. We therefore adapt our solution to each client, because standardization, as currently found in robotic finishing, is something the industry needs to collaborate for this meticulous operation.
Today, our systems help quality inspectors. They identify surface defects, but inspectors make the final decision as to whether the part is accepted or not. We are aware of increasing challenge of finding skilled manpower to perform these repetitive tasks. Our team of expert engineers continues to work hard to evolve the technologies and refine our solution so that one day, we can meet the primary need of our clients: a fully automated inspection system for critical components.
