NPI Measurement Hardware Adive

Ben1989
Hi all,

Hope you had a great Christmas and New Year!

I'm writing as I'm seeking metrology advice for products that will quickly go through our aerospace shop.

The products are simple, flat, relatively thin composite components. It will be an in-process measurement where only two dimensions need measuring; profile and hole true position.

If you refer to the very rough drawing I've attached. The component's thickness can simply be measured with a vernier.

At the moment I'm thinking of a Romer Arm but I'm wondering if there's anything out there where you can simply throw the component onto a surface and automatically be measured.

Hope I've described what I'm working with well and is understood Slight smile

Cheers, Ben

  • FIXTURES, these let you "throw a part" on and measure, if you want automatic, then you want a DCC system, like a CMM.

    Make a simple fixture, attach it to the table, align the fixture, make a program that checks the part (and aligns the part). Then, as long as the fixture doesn't move, you 'throw a part' on the fixture, hit EXECUTE.

    Simple fixture can be made from RAYCO items. 3 of the small magnets, 3 'stop' blocks, and let the CMM do it's thing., IF they are not ferrous metals, RAYCO also has vacuum items that can be used instead of magnets.

    It's a composite so non-ferrous. It would need clamping to a flat surface/fixture, feeler gauged and then inspected. Due to this I don't feel touch trigger can be used as it's too thin to get into the holes without the ruby hitting the table leading to false measurements.
