Non-Contact Measuring Equipment Recommendations wanted

Hey everyone, I have another question :rolleyes:

The company I am interning with is on their way to becoming ISO compliant. In doing so, the QA manager and I took a serious look at our final inspection area and found that because our final product is made of hardened tungsten carbide, they go through carbide tipped calipers every three months or so. The OD jaws are usually fine, but it is the ID's that wear quickly.

This was shocking to say the least. I have been brainstorming ideas to get around this problem and was thinking about measuring equipment that doesn't contact the parts. Something along the lines of laser mics or ultrasonic measuring equipment.

The measurements we deal with are no smaller than .001". I have never used a laser mic before so if anyone has any insight, cautions, suggestions, or any input at all I would greatly appreciate it. Or if anyone would suggest any piece of equipment to measure ID's that wouldnt wear as quick as the calipers, it would be a big help. If anyone needs additional information, just ask!

As always, thanks!

You're measuring IDs in .0001" increments with calipers? Are these features round? How would you use a laser mic to measure an ID?

Not knowing the size or weight of your parts, I'll throw in an optical metrology system for consideration.

Gonna be more expensive than Laser mic's, but you may find that it replaces/accelerates some other tests or equipment as well... I sure did. We now use it for nearly 100% of our dimensional tests.

Check out the applicability of a MicroVu Vertex, OGP Flare, etc.

Hello Augustiner,

In looking at your problem, I would suggest that you could use Air Gaging to measure your IDs. The other suggestions are good but if you have to measure the parts in the manufacturing area, then neither one would probably satisfy your needs.

I did not see any sizes and do not know how many different bores you are measuring. However, air gages are very accurate and last longer in the shop. The problem is the measuring range is very small. That would most likely require you to purchase several or more air gage spindles and ring gage masters.

The best suggestions I can make is for you to consult a "Gage Guy" from your community of vendors. You could show them your applications and then they could provide catalogs and information for your company to use to make a proper determination and not waste money on equipment that may never be used.

Regards,
TM
