I have run into a bit of a problem here due to past practices that I am hopefully going to be able to correct. However, the solution to the problem is a little elusive, and I am hoping that someone here has run into a similar situation that they have solved, and can provide some suggestions.
We currently inspect some of our parts using a dual level air gauge (dual level holes in the part) and two columns. The original thought was to check the last hole machined – if it was good, then the supposition would be that the previous holes are ALSO good. This was a great thought, however it is proving to be inaccurate.
I am now looking at having a gauge designed which will check EACH of the holes individually, at two levels. The problem lies in evaluating the ‘measurement’ of the holes. As currently designed, this would require 8 columns for a 4-hole part. This is not really feasible for a variety of reasons.
I am not concerned with the operator being able to evaluate the actual diameter of the hole(s) being checked – just to be able to determine a pass/fail condition on all the holes at the same time.
Does anyone know of a method to evaluate multiple inputs from an air gauge, and signal a pass/fail?
Thanks
