Surface coverage inspection

Surface coverage inspection

Surface coverage inspection


I am testing some nylon-based abrasives, and some of them leave nylon on the surface of the work piece during use, and shows as a black “smear”.  I am trying to quantify this problem, and am looking for a method of measuring the area covered by the nylon that is quick, easy and as always cheap!!!

Any suggestions would be gratefully received.

Thanks in advance,

RE: Surface coverage inspection

I am not sure if this qualifies as Cheap or easy, but it sounds like a Machine Vision System using a blob tool could help you with your application.  These systems are available from $2,000-$10,000 per camera.  If that is too much money and you are looking for something to try offline on a very small number of samples, you could take a black and white picture of the smear then import the image into a demo version of the software.  If you are looking to buy, I would suggest Cognex (www.cognex.com).  If you are looking to do the work offline, Cognex sells an offline package for about $500.  If that is still too much, DVT (www.dvtsensors.com) gives away trial versions of their on their web site.  Not as good as the Cognex, but you can't beat the price.

Good Luck!

RE: Surface coverage inspection


I thought it might be something along those lines.  I will have to see if I can persuade someone to part with some money!!!!

Thanks again
