Starting to get Involved
Hi All,
Im in the process of validating a part that has an internal thread (8-32 UNC -2B). In order to calculate capability on this thread i need a method of accurately measuring the thread.
If we validate using the go/no go gauges and 100% verify the threads this will mean that we will need to continue 100% verification on this feature going forward.
We are trying to reduce the ammount of inspection required on our parts by proving capability and based on previous parts that we have validated our threads are one of the most capable features on all parts we machine.
It would be a shame to have to 100% check a feature that we know is capable.
We have looked at a number of options, thread clock (cannot get one small enough), thread putty (not accurate enough), sectioning and measuring on comparator (too expensive, 150 sample of parts required).
Can anyone offer some advise on a method of measuring this feature or alternatively a method of validating this feature that will not lead us to a 100% verification on all parts going forward?
Thanks
