Variability is a fact of life in manufacturing environments, impacting product quality and yield. Through this course, students will learn why performing advanced analysis of manufacturing processes is integral for diagnosing and correcting operational flaws in order to improve yields and reduce costs. Gain insights into the best ways to collect, prepare and analyze data, as well as computational platforms that can be leveraged to collect and process data over sustained periods of time. Become better prepared to participate as a member of an advanced analysis team and share valuable inputs on effective implementation. Main concepts of this course will be delivered through lectures, readings, discussions and various videos. This is the fourth course in the Digital Manufacturing & Design Technology specialization that explores the many facets of manufacturing’s “Fourth Revolution,” aka Industry 4.0, and features a culminating project involving creation of a roadmap to achieve a self-established DMD-related professional goal.

Introduction to Advanced Manufacturing Process Analysis
The purpose of this module is to introduce the concept of advanced analysis in improvement of manufacturing processes. Also, this module will help you to understand the difference between discrete manufacturing and continuous manufacturing.

Welcome to Digital Manufacturing and Design or DMD dialogue session.
As your moderator, I will take you into companies where we will have
conversations with industry partners who share our manufacturing passion.
More specifically, they share our passion for how digital manufacturing and
design is transforming the industry
[MUSIC]
We're extremely fortunate to be able to share some firsthand experiences with you.
>> This DMD dialogue session will focus on discrete manufacturing.
Today, we're visiting V-Lake Industries.
V-Lake Industries is a Buffalo-based machine shop that's been servicing
the western New York area for over 20 years.
We offer a wide range of CNC machining services, multiple vendor-based amenities,
and an array of custom work.
The V-Lake Industries facility is equipped with state-of-the-art machinery that
provides high precision and high volume production.
We'll explore their 2 and 3D million technologies, their turning technologies,
CNC routing capabilities and their inspection procedures.
Let's go to V-Lake, everybody.

>> A customer will generally send in a quote, or request for a quote,
with the number of pieces they're looking for, a drawing.
I will go through that drawing, look at what the requirements are from materials,
finishing, give an estimate of how much time I think it's going to take for
us to do that on what machine.
I'll put those numbers into our ERP system.
So it will give me a good estimation of how much
that job is going to cost us to make, and how much we should charge for it.
I'll pass that information on to Keith.
He will make a decision, final decision on what the price of that will be.
I will load that back into our ERP system,
those final prices, issue the quote from that system to our customer.
If it's accepted, they'll issue a purchase order.
I can then load from the quote that we gave directly onto the order.
I will, [MUSIC]
Process the order in our system,
which automatically takes the raw material inventory out of our system.
Will automatically generate some scheduling for our mills.
I will print out routers for each one of those, we have a folder for each part.
If it's a new part, I'll make a new folder that'll contain the drawing,
a blank inspection report based on the dimensions of the drawing.
And pass that on to the production manager.
>> Once Dave types up the order, then it hits my desk.
So I approve the delivery date to make sure that we have what's in front of us,
and if we can make the delivery date.
And then from that point it would either, if it's a new part, I would program it.
If it's existing jobs, it would go on the floor to get cut and run.
We use Mastercam, which is a cam software.
So I receive a 3D model, I put it into my cam software and
put it in, orientate it the same way it would be done in the actual machine.
And then from there I start creating tool pads from that geometry on the 3D model.
Once that's done I post out the program.
So what it does is it takes it from the computer language and
puts it into the CNC machine understands, G code, M code.
And from there on we go to the machine.
>> The first piece gets machined at the mill, or
the lathe, depending on what product it is.
The operator will do the initial inspection of that piece.
When he's happy with it, it goes to our quality engineer.
He will do a complete full inspection of that part.
>> So, I receive a part and some of the main tools I use are digital calipers.
I'll use that to check a length, or a width, or a whole location.
I might use gauge pins to check a diameter of a hole.
Or the width of a small slot or something.
If it's a critical, tight tolerance I might use a micrometer.
It's a radius gauge, it kind of varies to the feature that I'm checking.
The CMM, it's used with a computer program.
And the way we use it, is we get a solid model from the customer.
We take that model and we map out all the features on it on the computer.
And then we use the CMM to track were does features are on the part and
make sure they're in the proper locations.
It uses a probe, the probe pretty much locates all
the different features and just compares to the solid model.
>> Once he's happy with that, that piece goes back out to the operator and
to continue on with the rest of the run.
In between time, the operator is checking each part as it comes out of the machine
for some critical dimensions to make sure everything's still on spec.
Nothing's changed in the machine, the material hasn't moved or
anything like that.
In addition, our quality engineer is going around and checking.
>> Take one, just randomly, out of the sample of what we've ran today and
I take that back to my office.
I check it fully against the print, so I check every single dimension.
And then I check the finish and everything totally to the print specifications.
And then I have a log where
I indicate that it's good, we can keep running that part.
Or it's not good, then I have to tell the operator or
tell the production manager, to stop running that part.
And we have to figure out what the problem is and
fix it before we can continue production.
>> Once the machining is finished it will go on to the finishing area.
So a lot of the parts need to be either deburred, polished.
It'll go back to the quality department,
it gives it one final visual and tactical check.
And then it's ready for shipping, or it's ready for for plating.
If it's ready for plating, it goes on to our plating rack,
goes out to plating, comes back.
It's another visual check to make sure nothing's happened to it while
it's at plating.
The plating is adhered, there's no issues with it.
Once we're happy with that, then it's ready for shipment.
We do collect all of our inspection data.
Whether it's a manual form that has all of the dimensions, conventional information
on it that the operator and the quality engineer are filling out.
Once we are ready to ship that part and everything is
appropriately filled out on there and we're happy with the quality of the part.
That information is scanned and saved to your system.
So we have a digital library of all the parts that we make.
The drawings are in there, the completed inspection report.
So a history of all the parts that we've made on that part by purchase order.
So we can go back and look at each one, at the inspection date that we recorded for
each one of those parts.
