Gage R&R/MSA for In Process Measurement System in a Turning Machine

[beikmar]

Hello,
looking and searching this forum i got a lot of information but not yet sure how to manage the following situation:

we are installing a new production line with a few machines using a in process measurement system to adjust the diameters for turning operation. Question: what is the right approach to demonstrate our OEM customer that the measurements are reliable ? The part is given into the machine by the operator, clamped and then automatic process starts....

FYI: We have Minitab and can use this to do any calcs

So - thanks in advance for any quick feedback as our customer is in tomorrow ;-)

Somehow you need to get output of what the machine measures. The most clever thing to do would be to prepare 10 parts with variation within the expected process range. Program the lathe to touch off on the parts (without turning) and record the data. It would be a Gage R, which, if repeated over several intervals to get stability, should work. You can also use different operators, in case there is any operator dependence on loading the chuck. If so, you can do a regular gage R&R.

One of the down sides of this approach is you miss some of the error from vibration, surface finish, etc. that it will see during turning.

Just a suggestion - hard to ponder without the machine and its details in front of me....
