Technical & Dinner Meeting
Speaker: Bob Doering
Topic: CorrectSPC: 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! I go into the correct distribution, and the proper setup of control charts that allow absolute control of the process! I go into how Cpk's cannot be calculated for precision diameters and lengths - because the distribution is non-normal (see AIAG PPAP 4th edition 2.2.11.5, NOTE), and how compression 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! |
