Okay here goes. . . .
Lets say we have a production run or 1 item per month (perhaps), we 100% digitally inspect (CMM) every that part every time. We need to start to reduce the inspection time allocated. How do we do this? There are several options:
1, Inspect 10 off to determine capability etc and then start to reduce inspection to inspect 1 miss 1, inspect 1 miss 2, inspect 1 miss 3 etc. Therefore reducing the inspection required whilst still inspecting the part as it comes through.
2, Once we have a proven stable process (inspect 10 @ 100%) start to reduce the number of measurement points inspected. Therefore previously you measured 500 points on a surface, you now only measure 250 points. The problem with this is that you will have the set up time and CMM tie up remaining.
Is there any advice or suggestion out their so we can apply this? Remember, we do not have any constant production runs so the usual sampling plans do not seem to apply.
