Question Automating variable inspection - Calipers, micrometers, and optical comparators

He everyone. I guess this is my first "Real" post.
anyway - I'm looking for a faster way to measure outside dimensions (and even some inside dimensions if possible) on a threaded part. We make valves - relief valves, check valves, etc and this would be used post machining to check component parts, as opposed to assembled valves.

Currently we use calipers, micrometers, and optical comparators to measure diameters, thread pitch, length, etc.

I would like to automate this in order to speed the first article and in-process inspections.

I was wondering if any of you might have a recommendation.

I've used OGP's Smartscope in the past for extrusion profiles, but this is a pretty complex device and would take a lot of training if I would want machien operators to do their own inspection some day.

Thanks!

Use a laser micrometer.
Search laser the internet for "laser micrometer"

Caution
1) surfaces must be clean
2) centerless ground valves must free of odd lobbing otherwise the measurements will not reflect the true OD.
3) measurements should be made at a slight angle relative to the grinding lay or else the the resolution will vary due to the surface finish.

You might want to look into a portable articulating arm CMM (such as those offered by Romer or Faro Technologies). These can be equipped with laser-based visual measurement devices, and are relatively economical (extremely in-expensive for a CMM).
