@Mike-Carnell No worries! I appreciate your advice! You’ve been gracious enough to give your opinions to someone who is still fumbling their way through this.
I agree that measurement options 1 and 2 should be disqualified since they don’t seem to be able to control for all 3 axes. However, there is resistance to this because, you guessed it: “…[Read more]

Thanks for the response. To clarify, the parts are generally smaller (always less than 10″ x 10″on the profile and varying in length); the difficulty of squareness is that it has a tendency to interfere with our machining tolerances (typically +/-0.010″); and perhaps I worded it wrong but this is concerning cutting product…[Read more]

Our facility has 2 main functions:
- Cutting Material (custom extrusions, plate, regular stock, etc.)
- Fabrication (CNC, punch, drill, bend, weld, etc.)
Cut material can be sold directly to customer or sent to fabrication for further processing.
We have had an issue with ensuring that product is cut in square according to…[Read more]
Aaron Olson started the topic Are EngineRoom and TRACtion Good Tools for a Deployment? in the forum Implementation 3 months, 3 weeks ago
I know that minitab is a very popular analysis tool for GBs, BBs, and MBBs and I’ve been looking at an alternative:
Does anyone have experience with Moresteam’s TRACtion and engineroom applications?
Are they helpful (worth purchasing) for a LSS deployment?
Are there better tools?
I agree that this is a lot of potential waste but I have a few questions to clarify:
-Where does output compare with takt time?
-Is demand higher than current capacity and/or output?
-Is there another process that can be mixed in to utilize the waiting time of the operator (assumed that it’s an operator and not an automated process)
The ideal…[Read more]
I’m assuming this is a homework question so I’ll point you to a place where you can do some learning – I’d take a look at the following definition that can be found on this website:
It lays out the formula pretty well.

Thanks @mike-carnell for the response!
We are an aluminum distributor that purchases from mills and extruders, cuts bars to precision lengths, and machine parts if necessary.
These tubes are cut to about 2″ with a +/- .005″ tolerance. We use automatic saws to cut down from 16′ lengths.
We have some data stored in an SPC program – I am going…[Read more]

I’ve begun work on a new project.
I was given the following problem to work on:
A long-time part needs to be examined and cost needs to be reduced.
Leadership observed the wastes of:
raw inventory (we get get large shipments monthly),
expenses in packaging,
The part is essentially an aluminum tube that gets…[Read more]
I’m not entirely sure what they mean but here is a handy wikipedia article:
It appears as though they are descriptions of the shape.

Thanks for the advice. I am assuming that you picked up that comment from a post from almost 3 (or more) months ago. (Or maybe there’s another Aaron out there?) My thoughts have changed a bit after some experience and seeing some commentary from those that have been through it for a while.
I would agree with you that it is a…[Read more]
That makes sense now.
If you don’t mind the asking:
-What is your current scrap rate vs your target scrap rate?
-How significant of an improvement are you seeking (%)?
I would limit the scope to the stamping area with ‘Y’s being measured at the end of production after stamping and after final assembly. With your last project being…[Read more]
your scope does, in fact, seem quite large. Not that it won’t be worth it but it will be daunting. Your thinking is right but make sure that your evidence/maps/charts/etc. actually take you up that river.
My SUGGESTION is that you pick a single final product or final product family that your are seeing unacceptable levels of scrap.…[Read more]
I might be assuming here, but I think that @Daniel.S is referring the article linked by “Burns”. At the bottom of the first linked article is an explanation on why his particular services/products are more sound than the training and tools utilized in Six Sigma methodologies. I had a similar thought cross my mind while reading his…[Read more]
