Re: Fix the Process and not the Part

NO RATINGS

This Sherlock reminds me of some things I heard when reporting on machine vision and inspection equipment. Mainly, how do you tell when the test/inspection equipment is the cause of a failure, and not the part? The big automated production and assembly systems have the ability to gather data, via software, which can be aided by the use of machine vision, to allow just that. But it all has to be configured correctly, and that takes a lot of time and energy. I heard from MV vendors that often that doesn't get done.

Case of the failing c cells.

I have designed a lot of industrial testing machines and one common feature on many of them was code to detect three-in-a-row failures at any test position. That would either set a warning flag or stop the machine, since the processes were stable enough to make 3 in a row faults be a warning about some kind of process deviation problem. Of course if the tester did not record which fixture position the faults were in then it would never have spotted the problem. 

But it was certainly good detective work to locate the cause.

Collecting stats on which position failed is a great idea William.

Monitoring failures for each test position is usually mandatory for quite a few organizations. Others just monitor for three in a row on the whole machine. The reason is that in an automated line there could be a test fixture failure and it could result in a shift's worth of rejects when there was nothing wrong with the parts. So it is very good economics.

Seems Obvious

Your solution seems so obvious, yet if there is no one there to explore the problem people just believe the machine they are told to I suppose.

Charger

I have a battery charger that sometimes says my batteries are fried and sometimes they get the green light. I'd like to know why that happens.

Actually I have 2 chargers. One will say yes and no depending on the day, and the other always says yes(green light). It's very annoying and I wish I had an answer as to why this happens. Either way, the batteries work...I just never am sure to trust if they are fully charged or not. I am about to just get all new batteries and if the chargers say bad...toss the charger.

These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
Ear-based heart-rate monitoring gained momentum recently, as sensor maker Valencell Inc. announced it has licensed its biometric earpiece technology to Samsung Electronics Co. Ltd for use in so-called “hearable devices.”
