We often perform capability studies for our customers on dimensions, but now we are faced with a dilema. One of our customers is asking for a capability study on a measurement that is defined as a range on the print. The print says that any measurement between .33 & .80 is good, without defining a target. We have completed the Gage R&R and the XBAR, R charts succesfully. The problem is we don't know how to do a capability study when there is no set target value. Is this possible.
