Talents and technology are critical to high-tech companies like Coherix. This is why Coherix has nurtured good relationships with research professors at the University of Michigan (U-M) in Ann Arbor, which is located within a 10-minute drive. U-M annually performs…
To join dissimilar materials, improve structural integrity and reduce weight, the aircraft and automotive industries are turning to the use of structural adhesives. To achieve optimum adhesion, adhesives must thoroughly “wet out” the part surface to be bonded, which means…
In the automotive and aircraft industries, adhesives and sealant beads are increasingly being used in bonding body parts, windshields, roof and many other applications. To ensure the quality of assemblies, a robust and reliable inspection of the bead volume and…
By Dallas C. Dort Your eyes see in true 3D. You can tell what you are seeing by the way light falls on it, of course — but, because you have two eyes, you can also tell depth and shape…
Baby boomers are retiring at the rate of 10,000 a day. As a result, the United States is losing a large portion of its experienced manufacturing workforce. At the same time, global competitiveness, especially in the automotive industry, is becoming…
When machine vision first emerged on the scene 30 years ago, customers were intrigued with the technology and they wanted to know how it worked and were excited about creating their own solutions. Universities clamored to do research in every…
In our litigious society, manufacturers need to prove their products were produced correctly. Therefore, they need to be confident they can retrieve information to have proof. The automotive industry is paying a high price in dollars and brand damage whenever…
Twenty years ago, the machine vision industry held out great promise that 2D vision cameras could solve multitudes of error-proofing problems in discreet manufacturing plants. Unfortunately, they proved to be temperamental and unreliable, mainly because the 2D vision cameras are…
Recently Coherix engineers and Fiat Chrysler Automobiles (FCA) engineers have been working jointly to develop error-proofing solutions in engine plants. After identifying eight specific problem areas, the team recognized that these were all old problems that have been plaguing engine…
First commercialized by Perceptron in 1983, line sensors were used to verify critical dimensions on automotive bodies to determine part-to-part variation. At that time, they were referred to as 2.5D (two and a half D) sensors. Recently many companies have…
