Troubleshooting gauge variation: Why you should have paid attention in math class

摘要

Thickness or gauge is one of the most important quality control parameters in film or sheet manufacturing. Disturbances in this steady state manufacturing process are the root causes of gauge variation. Some of these disturbances are random, while others appear and disappear at regular intervals. Cyclical disturbances can often be eliminated if they can be identified, but many rapid frequency disturbances are difficult to detect.
