JANUARY DINNER MEETING

Topic:  The Correct Use of SPC in Precision Machining

This presentation is very controversial, as it destroys the myth of the normal curve in precision machining!  It will show how the X-bar-R chart is the absolute worst chart for precision machining.  It goes into the correct distribution, and the proper setup of control charts that allow absolute control of the process!  It also goes into how Cpk's can not be calculated for precision diameters and lengths - because the distribution is non-normal.  It will cover how compression of control limits increases variation, and is not continuous improvement!  It sounds like blasphemy, but it is all true - and once you see the facts, it is impossible to argue!
