I am automatically collecting process data from our ultrasonic welders. By using an individual / moving range control chart on seven different process characteristics, I have been able to reduce my process variation tremendously so that our product is much more consistent. The problems I experience are small mean shifts, which trigger alarms. I have not been able to determine the root cause of these shifts. I also question the importance of these shifts to the actual product, as most of them are quite small. Currently, my process triggers additional testing when an alarm occurs. Is anyone else experiencing this type of problem?

At present, the Americas have a registration scheme for AS9000 that has primarily involved US aerospace companies and their suppliers, with only a few establishing registration requirements and deadlines. Aerospace companies in the European Union and the rest of the world are in the process of establishing a "registration scheme" for EN9100, the European equivalent to AS9100.
What is expected is that the EN9100 registration scheme will be established in the early part of 2001 and will probably receive greater consideration from the European and other aerospace primes after AS9100/EN9100 is revised in the first half of 2001 to align with ISO 9001:2000. In the Americas, the AS9000 registration scheme will be updated to AS9100 and then gain greater attention after the ISO 9001:2000 alignment is completed. It is not yet certain how many aerospace primes and their top suppliers will be establshing registration requirements and deadlines. Look for customer notifications and other reports.
