Q
Re: Control Chart out of control???
I am with the others who say there is not enough resolution in your device but there is something different in the measurments as well.
Do some measure hot of the wheel and others after it has cooled slightly, does one person have a tighter grip, are there more than one device in use, more than one operator, more than one machine, more than one appraiser???? At what point in the data is the whell dressed, where was the wheel bumped a little to hard by the work piece? All of this needs to be answered in my opinion if you are going to make the control chart work for you instead of being a "dead" tool.
