Hi Guys,
Been using this site as a resource for years and just decided to sign up with a query of my own. Also looking forward to lending some input where I may be able to help out.
Jumping into it - I've been racking my head on how to go about measuring the following:
Characteristic:
Feature: .030" +/-.010" internal radius, 360°
Location: Bottom of a 1.4" diameter, 22" long blind bore
Material: AMS 5648 Steel, 32 Ra Surface Finish
The customer has indicated this is a flight safety characteristic, therefore:
Quality Requirements:
-100% Inspection, each part
-1/10 tolerance resolution minimum on gauging equipment
-Capable to pass gauge R&R 20% or better
This is a high volume for us, so inspection turn around time for this particular feature should be only a couple of minutes per part (setup time of ~10 minutes would be acceptable).
Unacceptable methods:
-CMM (our probe tips/extensions would not be capable)
-Mold/Comparator (we use a 2 part mold and optical comparator on other features, but wouldn't be timely enough for this)
-Contourograph (Contracer) (we have one, but likely wont reach, and setup plus 360° measurement, even if just 8 places, would take too long)
-A Go/NoGo setup. Must be able to produce variable data.
Potentials:
-Laser/Direct Optical: Possible, but cost may be a factor.
-Light Projection with Direct Visual Comparator: I saw a post where this was recommended as a solution to a guy working with a busing, but not sure how accurately this could be setup.
Hope someone here has a good idea - or at least finds the brain exercise that comes with this entertaining! Thanks for any thoughts on this one.
