Inserts Driving Me Bonkers...A Better Way?

Thanks for reading.

I've been working on a project. It's actually starting to drive me a little crazy. We need to pass a Cpk on this thing before it hits production.

The main issue holding up everything is the reporting of the inserts. Rarely do they check good. Right now, I have one part out of 11 that is good across the board.

This is a molded composite part. With 10 inserts molded into it. The inserts are either hand loaded by an operator or an insert loader that was not made very well.

The flange with the inserts is facing YMINUS. All my Basic dims match up to print. The X values are sopt on for the most part. It's the Z values that are off anywhere from .005 to .030".

Again the inserts are manually loaded.


The also when hand loading have to tap inserts on extended pins.

I know it isnt the CMM. Management says its the CMM.

These inserts as well have mmc as do the datums. Any ideas on how I could maybe can measure these inserts better, if at all?

Sorry about the book and thanks for your time.

  • If you are seeing variation pretty much exclusively in the Z axis, explain that to your boss.

    --Maybe your composite part needs to be restrained?

    --Maybe the template or jig they are using to cut the holes for the inserts has a defect on it (raised material/debris/damaged pocket or face) and needs to be repaired.

    Comprehensively problem solve, instead of telling them "it's bad mmkay". 

    I guarantee not only will they value your approach, but you maybe could use it as leverage for a raise in the future.
