Sheet Metal Automatic Split Detection

AI Thread Summary
A project is underway to develop a method for automatically detecting splits in pressed metal during the production of car panels. Potential detection techniques being considered include light, infrared, and harmonics. There is also interest in Barkhausen Noise Analysis for inspection purposes. The discussion seeks additional methods or information on these techniques, particularly regarding their application in sheet steel. The goal is to enhance quality control in manufacturing processes.

I am running a project on trying to find a method of detecting splits that are present in pressed metal.
The system is to be placed into a manufacturing press line of car panels that will automatically detect and notify when a split has occurred during production.
Some methods I have come across include the use of light or infrared and also heard ideas about the use of harmonics.
Does anyone have any methods that they know of? Or more information on the mentioned techniques?

Thank you

Anyone know of any companys that use this tech or of any products appropriate for sheet steel?
 

Thread 'Race car suspension Class'

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
