Correct SPC Presentation
This presentation is very controversial, as it destroys the myth of the normal curve in precision machining!
We’ll go into the correct distribution, and the proper setup of control charts that allow absolute control of the process. We’ll cover 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), 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.
Too Lean Presentation
Listen to what happens when a simple attempt to implement SPC unearths some disturbing quality and process design flaws.
Everything from gage choice and usage, process flow, machine location, material temperature control and incorrect specification all come together to create a whirlwind of chaos.
Out of this case study arises the third leg of the Value-Added concept. It is not just Value-Added and Non-Value Added any longer!
This is a real case study, scrubbed to protect the victim. See how a few useful tools sort out the mess. But can it be totally fixed? Find out!
Capability Indices - Are they capable?
Customers have forced onto their suppliers the classic Ppk and Cpk capability requirements - yet, few understand the limited application or meaning of these indices.
Many automotive customers are oblivious to the limitations specified in their own AIAG manuals!
Stop...take a breath...and discover what is really going on with capability indices. Find out what their value - if any - really is! Presentation includes case studies concerning capability analysis of non-normal characteristics.
The Mysteries and Miseries of Gage R&R - A Peek Behind The Curtain
For years, many people have believe there is black magic in the old Gage R&R that will proclaim if a gage is "good enough" or not. Truth is, there is more to it than a plug-and-chug test! Proper preparation and execution, along with some process knowledge, goes a long way to meaningful results! Should you "mark parts"? What variation should the parts have? Should you do Gage R&R annually? What does Gage R&R tell you - and what does it not tell you? This presentation unravels the knot of Gage R&R!
Automated Tool Compensation - Should I Just Turn It Off? (NEW!)
Many people do not realize that most automated tool compensation is simply automated overcontrol. On top of that, the compensation "becomes" the process, masking underlying process variation, such as tool wear. What if we really want to see what the process can do? This case study shows what you can learn about your process and the effect of automated tool compensation just by turning it off!
Jack Skellington on Vision, Training and Customer Satisfaction (NEW!)
The Nightmare Before Christmas was a quirky film that came out in 1993 and still has many fans today. The film has within it a parable of poor change management. The presentation reviews the lessons discovered in company vision, training and customer satisfaction as illustrated in the film. You will never see the film in the same way again!
