G'day all,
We use electric terminal crimping machines in production, crimping small automotive style terminals/pins to wires, e.g. 20 awg. Typically no more than 100 crimps per day per machine.
Every morning, and each time a terminal reel is changed, each machine is verified and calibrated using pull force testing on sample crimps.
- If the result is PASS and >~15% above minimum spec, no adjustments are made,
- If result is PASS and within 15% the settings will be adjusted, retested and then commissioned for use,
- If the result is FAIL, QA Manager is notified and we would investigate cause as well as impact to items produced.
Test results are maintained in hard copy as records.
Question - is SPC appropriate here, and if so how would it help? I figure not due to the daily verification testing. Each time a machine is recalibrated the results are independent of the previous one.
Open to ideas...
Thanks
