Do you implement real SPC not just a paper work?

[cqt18060180]

i am chinese guy as QE, but for my experience and my saw, SPC just a tool for customer audit only, so i am curiouse to know the implement from your work experience, since the SPC is hard to acchive if real implement

Hi,

SPC is a tool. A good tool that reflects how the process performs and ultimately one of the best cost monitors implemented. Sure, many people submit false data but that is only a reflection of the true morals of the company.

Sample: If a company, or individual "supervisor" requires the submission of false data what could they do to your employment records, performance reviews, promotion possibilities?

In reality an organization as well as an individual have morals.



Al... "on his high horse!"

Hi, SPC is very useful tool. I used it in dimensional control, and it works very well.

but it means we have more times for linestop, it will hard to ship product

If you like to see SPC implementation you have to go to auto manufacturers. They are the people who implement this tool very widely and with true letter and sprit. While I admist that there are other industries which are implementing these tools successfully.

Hi cqt

SPC covers a very wide range of things. It's not just monitoring your output. You also monitor the things that affect what you make.

Suppose you have 3 machines making a part, a CNC lathe cutting a part to a particular diameter. You have a problem with the diameters. They are not all 50mm +/-0.05mm.

If you look at the output of each lathe individually, you might find the following:
Lathe 1- 50mm +/- 0.03mm
Lathe 2- 50mm +/- 0.02mm
Lathe 3- 50mm +/- 0.09mm

In this case, the problem is lathe 3. Now you know what the problem is, you can do something about it. Once you have fixed the problem, you need to stop the line less often.

I've implemented SPC in many organizations and have always found it quite useful as part of a suite of tools to improve quality reduce cost and decrease cycle time.

As a Customer when I audit my suppliers (many in automotive) I always look to see if the supplier is really using SPC or if the charts are just eye candy for auditors.

Yes, in the beginning you will stop the line - but you will get better results.

If you have many processes that are out of control you may need to prioritze which ones you will focus on improving and use acceptance sampling only on the other processes. you don't need to put SPC on all processes at once...

I always say you can process without SPC - just as you can drive a car without a gas gage. But....having a gas gage - or actually knowing what your process is doing - sure seems like it would be more helpful in the long run. It keeps bad things from happening that you could have avoided.

Hello.

I have a question for you.

What is the qualification for a Quality Engineer in China?

I hope you don't mind me asking.

Thank you.

I believe some bigger orgnization have the ability and resource to do this, eg. GM, Ford

But some tier 1 or tier 2 supplier present to you the SPC and GRR may not be real even you get the coutinuous chart

i am curious for the analysis when the trend chart is going bad, but point is under control also, i think you should call a meeting to solve this trend right? so if like this , if you were one OEM company with some many assembly lines how to do
