A podcast for mechanical engineers beginning their studies in Design.
(Music)
but not exclusively towards
my students in design one.
Um, so today we're going to talk to, uh,
we want to talk about
industry a little bit more heavily.
Um, and want to talk about, want to start
off with how does, um, university sort of
prepare you for industry.
So what kinds of units really sort of
mimic what's going on in
and around the universe.
Um, so Mike, you've been in and around
the university system as, um, a staff
member here at a university for what?
Seven years, seven years.
Yep.
Yeah.
And you have a unique perspective because
you work for the faculty rather than a
department, whereas I'm
working for a department.
So I'm, I, I teach almost
exclusively design units.
So I teach the kinds of units where
problem-based learning is
well, and truly ingrained.
It's well known to work
really well for students.
Um, although it is slightly artificial,
we can't do everything the way we'd
normally want to try and do it in
industry per se, but we
do our very best for that.
Are there any other units that you've
noticed that sort of
have that kind of impact?
Oh, you're putting me on the spot.
Um, any other units other than design,
it's funny, it depends on what your
definition of design is, right?
And that is very much a discipline
specific, uh, definition in part.
Um, and, uh, of course, the phase that
students are in at a given, you know, uh,
like whether they're first, second,
third, or fourth year, or, or
postgraduate really
contributes, I think to that as well.
Um, so maybe my simple answer is that,
yeah, a lot of those
units are design units.
The intent of those is that they do
replicate, um, uh, industry practice, at
least try to in
microcosm or, or whatever.
Um, but then the, the
gambit, uh, is that a word?
Of, of different types of
design units is quite large.
Like, as you know, um, from experience
with final year design versus second year
design, and then projecting back into
first year design, those are very
different, uh, beasts.
And then master's design sort of, uh,
because I've taught into master's design,
master's design kind of opens up to, like
you said, the different, the different
disciplines and what sort of constrained
or defined as design and the real
worldness of those sorts of things.
So, um, I'm going to pick on civil
engineering, not because they're bad or
anything, but thing that I found
fascinating the first time I taught that
was when you're talking about design and
the integration of diversity in teams
from a civil perspective, if you're
looking at a site, then they want to have
traffic management engineers and they
want to have people who are doing
structural engineering work and they want
to have environmental.
So within civil engineering, because the
scope of civil engineering is so large,
they have a lot more diversity than what
we might have in mechanical, even though
in my units, like my earlier units, we
would have mechanical students, robotics,
mechatronics students and aeronautical
students, but civil engineering have that
broader and bigger diversity throughout
their entirety of their degree.
I think so.
I, you know, I'll bring up somebody who,
who, I won't bring the person up, I
guess, but I'll make reference to someone
I know who argues very strongly, that,
you know, structural engineering is not
the same as what a lot of people think of
as civil engineering.
Now, Kathy, I always think of structural
engineering as that's what civil
engineering is, but I'm
actually wrong, right?
That's just my
experience, my exposure to it.
The only civil engineering I really did
other than a bit of soils and things like
that was structural engineering.
Absolutely.
But, you know, they actually have their
own designation depending on what
jurisdiction you're in, things like that.
So yeah, absolutely.
And, and what you just mentioned,
actually kind of raises something that we
were discussing the other day is
the advent of data centers being so
prevalent in, you know, in engineering
right now, that data center, I guess,
infrastructure development, all the rest
of it, that that's a great project for a
civil engineering student because you get
to see all aspects of civil engineering.
And what we're talking about is, you
know, the energy aspect, the
transport aspect, structural,
there's water involved,
all these kinds of things.
Sorry.
What a large component of civil
engineering, actually, but like your
ability to deal with water has, you know,
there's almost no crossover into dealing
with, let's say,
structural steel or something.
No, definitely not.
Completely different.
And so different disciplines, right?
Yeah.
So, I mean, you know, your original
question about, are there other units
that are, that are doing this?
I mean, yes.
But we do tend to separate into, let's
say, there are units or courses,
depending on where you're coming from
that deal with
fundamental technical aspects.
Yeah.
There's design units.
And then there are those other kind of
experience based or, you know, industry
exposure based sort of
units and courses, I guess.
And that's probably the answer to your
question is yes, there are some.
And they tend to be in that, that
experience, working in a greater practice
or working in a learning.
Professional sort of professional side of
things, as opposed to the sort of nuts
and bolts as to how
engineering kind of works.
Yeah.
Because what does an engineer do?
I don't know.
Let's go with 60% of the
time, maybe 70 or 80% of the time.
Possibly 99% of the time is not
engineering stuff, but it's well, not
direct design engineering stuff, but it's
all the things related to it.
It's not, it's not the
down and dirty mathematics.
It's not sitting there with stuff.
A lot of what we do is communicating and
managing data and documentation and all
of those sorts of things.
And this is where a lot of students who
come to us go, Oh, I decided engineering
was right for me because I'm good at math
and I'm good at science and English is,
it's there, but it's not, you know, it's
not my, it's not where
I feel most comfortable.
But as you sort of grow into your
engineering, it is one of those things
that you go, actually, there was a bit
that was in my, you know, my high school
English classes that's really sort of
propelled me and really helped with that.
We talked to students a lot about
narratives of, of reports and stuff and
just how important that sort
of training has been for them.
But I mean, those aspects emerge in a
design curriculum though too, right?
Just because they're not, I mean, I don't
mean to, to silo everything here.
There are certainly units that are
focused on professional attributes and
things like that, which don't involve
design, for example.
But I don't think you can go through a
design unit, of course, without dealing
with some of those aspects.
No, I think you have to deal with it.
At least I hope you can.
Agreed.
I think that they sort of, they come up
in, in smaller ways, but
they still come up within that.
I think because most of the project-based
learning that we do, we never actually
work as siloed engineers.
It's very rare for an engineer to be
locked in a corner or in a room or at a
desk and just work by themselves.
They may have part of a project that
they're kind of working on independently,
but the majority of that then sort of
feeds back into a much bigger team.
I mean, you said smaller ways.
I mean,
yeah, maybe smaller ways in terms of
assessment balance, but perhaps even more
significantly in terms of
just getting through the work.
Yeah.
I mean, looking at your students,
how are they going to do it without
talking to each other on a regular basis?
Yeah.
Dealing with friction on teams,
you know, trying to communicate your
ideas when it's difficult to do because
you're a novice, you know, all these
kinds of things contribute a lot.
I was saying this to another colleague of
ours, even as recently as today, someone
said, it's really hard when you go past a
design unit, because a lot of the
students will be standing around talking.
And I said, yeah, but what they're doing
is really, really important because you
can't be creative unless you can actually
be yourself and you can't, and you feel
some sense of security around the fact
that your ideas aren't going to be
trashed and they
might be, and that's fine.
You mentioned creative.
Yeah, I know.
I'm going to pick up on that in a second,
but please finish your thought.
But you can't, you can't
be a creative engineer.
You can't bring forth ideas if you don't
feel safe and you
don't know those people.
If you've ever seen a brand new group, a
team together, then
they're very, very silent.
And it's building those connections that
allows you to interact with each other.
In a safe and meaningful way.
So to creativity, I know you're normally
the one who asks me questions to, to
progress the conversation, but I'm going
to reverse roles here for a second.
What in your view does creativity
contribute in the
engineering design process?
Ah, I think that creativity is one of
those very, very underrated things.
But I also want to clarify what I mean by
creativity in an engineering sense.
So lots of people think that creativity
is creating something brand new that's
never been done before.
Whereas I found that being a creative
engineer is taking things that have
already been done and
applying them in different ways.
So looking at the world around you and
the more you can sort of look at the
world around you and
pick up, how does that work?
Oh, that's a really interesting hinge.
Is that a friction hinge here?
How does, how does that work?
You know, what's going on there?
Why do they use a dovetail
joint in a set of drawers?
Like I'm talking innate, seemingly
unconnected engineering things, but they
all have engineering applications that
you can then utilize in different ways.
Well, here's a good example.
The Shinkansen in Japan that was creating
like the sonic boom when
they were going through tunnels,
and then they found a way to style the
nose, you know, or shape the nose in such
a way that it didn't do that.
That came from- The
inspiration from that was-
Biomimicry, right?
That was Kingfisher's, I
believe, from recollection.
I read a similar article.
That was creative, right?
But it wasn't creating something new.
It was, like you say, identifying that
there are other sources of information
out there, there's other
inspiration and things like that.
And I guess, I mean, you know, cause what
I was driving at is, well, how does
engineering differ from art?
If they're both creative pursuits, then,
you know, let's compare and
contrast along those lines,
mimicking biological process in art is
creative as well, right?
And there's plenty of that.
Totally.
And yet they are different, right?
And I think we can
acknowledge that it's very different.
And I guess I want to go to the, like,
okay, let's not just talk about art, but
let's talk about design, be it industrial
design or, I don't know, website design
and human interface
design and engineering design.
Because we use the same word and I'm
going to pause it that it's actually a
very different thing, right?
I think it is.
Yes.
It's not,
there are elements of
design in engineering,
but there's little to know.
There's far less engineering design in
other aspects of design, I guess.
Yes.
I think with confidence.
I think what you're trying to allude to
is that with engineering design, it's not
so much create something from nothing.
It's take your technical prowess and
knowledge and what you've seen in the
world and utilize that
into a different scenario.
Whereas I think that when you
talk about artistic endeavors,
someone will start with a slab of clay or
a blank canvas or a bunch of supplies
that they then construct into something
that hasn't been seen before.
Or a thing that they want to do.
Or a thing they want to do.
As opposed to a thing
that they have to do.
Now I know that that's a simplification
of artistic process.
But anyway, I guess I want to touch on
the fact that, you know, I studied design
a bit in university and then my first job
out of university was as a designer.
And not a lot of my colleagues, in part
because of where I lived and things like
that, had design jobs straight away.
They were doing other things.
But I went and worked a big automotive
manufacturer doing design and I was told
I'd be doing design.
And it was not at all
what I kind of expected.
Right.
I mean, to some degree, yes.
But I was generally creating drawings and
by that, I mean churning out drawings and
drawings that were 10% visual and maybe
90% informational, something like that.
And then...
Whereas an artistic endeavor would be the
exact opposite of that.
Yeah, exactly right.
So you know, 90% artistic endeavor and
10% information, maybe.
And then I eventually worked for another
automotive company where I was a designer
and I did even less, let's call it
design, as in creative process of coming
up with a solution to a
problem and things like that.
And a lot of it was, let's make sure, I
don't want to overgeneralize, but a lot
of it is let's make sure that our current
ideas are not going to fail, right?
Yeah.
And that they're going to continue to
meet specification or targets or things
like that, or we might change the target
by a small percent this year and we have
to make minor modifications.
And I think that, you know, in general,
that's what a lot of design actually is.
Right.
It's, it's, it's rare that you're working
at a startup that's coming up with a new
thing, albeit there are people who do
that clearly, but a lot of engineering
design is going through the paces and the
process of making sure that things aren't
going to fail while
still meeting their targets.
But even in those startup situations,
you're also having to...
You still have that responsibility.
So you might have more of what you would
deem design in there.
Excuse me.
Sorry.
It's late and it's Friday.
You would still have aspects of what you
would consider design to be in the
processes that you're having as an
engineer, but you still have to make sure
that is it manufacturable?
Is it going to be fit for purpose?
So all of these problems that, or surface
level, or not even surface level, but
very deep diving engineering things that you might want to do, but you still have
to be figuring things that
you would be thinking about.
Is it going to vibrate itself to pieces?
Is it going to cope with heat?
Is it, you know, are we, are
we dropping it in the ocean?
Like where are we putting it?
That sort of thing.
I guess I think of, you know, our
curriculum here at this institution and
we, we, if we look across four years of
design for a mechanical
engineer, for example,
you know, first year introduction, second
year three and fourth level, I think that
we transition from the purely creative to
the more balanced toward what engineering
design generally is on a day to day
basis, which is those things that you
were just mentioning.
I think we do do that
reasonably effectively.
There's like a gradient there,
I suppose, and a rebalancing.
And by the time you're exiting,
you know, the scope of your design, your
designed parts is small, let's say, but
the breadth is narrow and
the depth is much deeper.
Right.
I think that's, I think that's accurate.
And I think that the thing that a lot of
students who are coming into second year,
it's we, we don't give you all of the
technical sort of
elements before beforehand.
We get you to very much sit within that.
Yes, I can do this.
I can solve this problem.
And we do that for a number of reasons.
Number one, it's, it's kind of fun.
And, and that's, that's an aspect too.
It's like sometimes to do a design where
you have to stop, think about everything
and make work out every single detail
before you even start can be really,
really challenging, especially if you're
feeling that you don't necessarily have
all of the technical capabilities yet,
which is why we sort of add that you've
got this, give it a go.
Try early, fail early, pivot well, keep
going, you talk to someone about it.
And again, it's that
communication aspect too.
Yeah,
I think there's a lot about, well, I
don't know, for myself, a lot of that
once I went into industry was about
finding confidence in my own process.
Yeah, I was gonna say creative process,
but it's not just not a purely creative
one, but the process of just approaching
a design and and I was lucky enough to
have in my second role at a uni have one
that where I was kind of
given the time to make mistakes.
Certainly my first job, there
was no time to make mistakes.
And so you had to rely on weird
structures within the company.
But then I ran my own new product
development department after that.
And it was, you know, the
timescales were relaxed enough.
Yeah, you know, they could do that.
And so that's something that I didn't
personally have at university.
But I think we are
offering to some degree.
And I think we've alluded
to this in previous episodes.
But yeah, go ahead.
And it's okay to fail.
And we've had a lot of discussion before.
But the thing that I did want to raise
with you here is one of the things that
students really sort of
struggle with is diversity.
We talk about a lot of diversity within
teams and having different opinions and
different thoughts and not letting one
person sort of take over.
Let's take let's pause for a second.
Sorry.
Define diversity in this.
Ah, yeah, diversity in
this context, different ideas.
I was gonna say at university, though, we
can sort of constrained.
So in my second year unit where I do have
students who are who are choosing to do
different streams, so
mechatronics, robotics,
robotics, mechatronics, mechanical and
aerospace, we try and mix up which
disciplines the students
are going to come from.
And, you know, their cultural backgrounds
and all that sort of stuff.
But that's not what we talk about
diversity in industry, is it?
So when we're talking about teams and
diversity and having different people
look at design, because lots of different
people look at you design when you're in
industry, what's
diversity look like out there?
Well, I mean, there is though there are
sorry, there are those aspects of
diversity that you've just mentioned,
diversity of background and diversity of,
you know, race and sex
and all those things.
But then there's
diversity of like priority.
Right.
I think that's maybe what
that's what you're getting.
Yeah, absolutely.
And I guess I'm going to draw on an
experience that I had of doing design
related documentation, very important
design related documentation when
involving kind of
everybody in the company.
Right.
So we had our engineering office with I
don't know there were 10 of us or so in
there, but there's 75
people in the company.
And so most people are not an engineer.
Yeah, everybody's got some kind of, I
don't know, skin in the
game or some, you know,
they're attached to that project somehow,
be they from finance, or, you know, the
dispatch desk or manufacturing side or
the warehouse or, you know, whatever that
logistics, that kind of thing.
And we did a process
involving all those people.
And again, it is an engineering document.
It's an engineering
process, but we involved everybody.
And that was quite valuable.
It was,
were they cranking out the
majority of the work for that?
Well, maybe not.
But they had certainly had contributions.
And that was that was really interesting
to observe, I guess.
And this is when I was a reasonably young
engineer and got a chance to see this and
found it actually quite valuable.
Yeah, I was going to say, part of my
experience when I worked at Defence
Material Organisation, we did a tender
evaluation process for a project that's
still ongoing called
Project Overlander 121.
And we had people from logistics, people
from finance, people from engineering.
And engineering was split into, I think,
about 10 or 15 different areas.
We had three different vehicle classes we
were looking at and then people had their
specialisation within those.
But then we also had a
human factors related part.
And we had all sorts of, you know, how it
was going to be delivered, how wasn't it
going to be delivered, what kind of
spares would we need, etc, etc.
To sort of give a greater overview and
greater sight as to what the end product
would look like and how that would
function within a military aspect.
And I'm not even
talking about deploying that.
I'm just talking about
having the thing there.
Yeah.
So testing, etc, etc.
So and I think this is what's really
interesting is that when you start to be
involved with people from different,
different discipline areas, as in, you
know, across companies,
you start to see that, like you said,
people have different reasons for for
interjecting with those that we don't
necessarily think about.
But that diversity is
really, really valuable.
One of the processes that quite often
happens and it came out of the Challenger
disaster, forgive me if I'm wrong for
this, but it's used a lot by the
automotive industry is called failure
mode and event analysis.
And that's a particular form of
documentation that we don't have time to
teach, but is done a lot in engineering.
Yeah, failure mode and event analysis.
Oh, no.
Failure mode and effects analysis.
But I've heard it called
so many different things.
And I think I mentioned you in the past
that at both Honda and Toyota, we had a
completely different
listening word called DRB FM.
And don't ask me to tell
you what exactly it means.
But it doesn't matter.
It's still the same document.
And this is like you and I, I think feel
very strongly that it's a
very, very important document.
And guess what?
So do the courts.
Yeah.
And this is the thing.
This is why I raised the Challenger
incident, because the process of going
through this particular documentation was
the reason why the organisation that had
built that rocket was not
prosecuted for that failure.
Yeah.
Because they could show that they had
done everything in their power to prevent
that from happening.
And they'd done an analysis as to what
the risk was and how that might fail.
And this is a really interesting point
for me, in part because my background,
but in part just because I find all this
stuff interesting, where, you know, law
and engineering meet, right?
Yeah.
So we have, you know, there's terms in
law about like, you know, would a
reasonable person expect and that like,
this is the kind of
standards to which things are judged.
And the same applies to FMEA, where it's,
you know, would a reasonable person, what
would a reasonable person with
appropriate knowledge expect to do as a
countermeasure or as a
design in this particular case?
And then you're documenting that, right?
Yeah.
At least that's the way I like to talk.
But also, how can you, how can you stop
what, what a reasonable person might do?
So how can you prevent them from putting
their finger in an electric, you know,
into a PowerPoint, for example?
And I know that that's very, very basic.
But how can you mitigate
that so that they won't do that?
And of course, then that ends up in
hierarchy of control
and that sort of thing.
But then these are all things that we
sort of stop and think about.
And this is the kind of thing that we
really do utilize in industry where we
pull in people from all kinds of
different areas and backgrounds.
So there's an aspect of risk analysis,
sort of documentation.
But I would say that
it's more than that, right?
It is more than that.
It's not just can you identify risks.
It's can you identify risks and can you
put engineering controls in place?
And then can you reevaluate
the risk after that is done?
And then can you adapt to new risks as
they arise and absorb those or
countermeasure those
and things like that?
It's like, I mean,
it's a document.
It's a living document.
People think that you
do it once and it's done.
And that's that way you're safe.
It's not not the case.
You have to keep addressing these things.
But it should tell the story and explain
to me or to any reader of it that you've
thought of everything, essentially.
And that's kind of the role of an
engineer is to make sure that they've
thought of absolutely everything.
And within the statistical norms of the
universe accounted for all those
potential, not just dangers, but but
failures of of specification and failure
of of structural integrity.
And a
failure doesn't mean that someone's going
to be injured or hurt.
Sometimes a failure is just that a
product is no longer fit for purpose.
And that's also something that as an
engineer, we're trying to avoid.
We're not talking
about design obsolescence.
Yeah, that's off the table.
Yeah, I don't like that either.
No.
And most engineers will feel that way.
And it's but going back to FMEA for a
second, it's the one thing I would love
to be able to have room to teach.
But it's really, really difficult with
the short amounts of
time frame that we have.
Well, and there's a risk
of not doing it adequately.
Correct.
With under experienced
or under motivated people.
And you wouldn't want to communicate that
is less important than it is.
So yeah, it's that, you know, I'm in two
minds about this as to whether or not we
should address it in university.
And I think we should introduce it, but
make it clear that it's an
introduction sort of thing.
So we don't, you know,
make people too complacent
around it and things like that.
But it would be good, I
think, to have some idea around.
I think the hardest part, though, is like
you said, it's it's not a one and done.
It's not you've done it once and
therefore you never
have to look at it again.
And I think this is where we would
struggle is because 12 weeks doesn't 12
weeks, 12 weeks when you're a second year
student, it seems like forever away.
But when you know the older you get, the
faster 12 weeks sort of travels.
Isn't it just the beginning of semester?
That's how it feels.
But, you know, you can
do a targeted one, right?
You can you can say, this is
a part of a larger document.
Why don't you focus on this and let's
really do this part
to death, essentially.
And, you know, we're talking about
breadth and depth before, so maybe you
could go really deep on one aspect of it.
That kind of thing.
You know, you
mentioned I you mentioned FMEA.
I tried to say FMEA before, but I almost
put the D before it.
Because there are two
clear camps around FMEA, right?
Not camps, I shouldn't say, but two clear
documents, which is D FMEA.
Yes.
And P FMEA.
Yes.
And so what do those stand for?
Well, D stands for design and P stands
for production production.
It is production and
production or product.
And here's something that we kind of tend
to we've neglected in
this conversation, certainly.
But I mean, how many engineers out there
are not design engineers,
but production engineers?
And therefore use P FMEA all the time.
All the time.
How many design engineers have to prepare
for production and therefore are involved
in the P FMEA process?
And, you know, then we get into that kind
of to and fro between the design office
and the and the factory.
The production office, yeah.
And yeah, that's it.
Like, what a great way to hand all that
over to write is through these documents,
which are, again, living and, you know,
participated in by all parties.
So just going back to that that idea of
two different engineering camps.
I shouldn't say camps.
No, that's not fair.
But two different engineering streams and
ideologies within one organisation.
Because design engineers do designs of
the product or the end thing that the
company is going to produce.
But a production engineer is the person
who designs how that's going to happen.
So they quite often have to take that
design and then turn it inside out.
Yeah.
You're dealing at the moment with an
organisation and dealing with production
tools and that sort of thing.
So you're looking at cavities within
metal, still called a tool.
And so it's really interesting.
The if you ever get a chance to see it
again, it's not something that we're
probably going to very deeply, but there
is two different camps quite often in a
manufacturing organisation where it's
design in one camp or in one office and
production in another office.
The difficulty is is that because they're
in different offices and they have
different roles within the organisation,
those communication between those two
groups is super, super critical.
Well, yeah.
And it's probably poorly done in so many
instances too, right?
And it's something that requires a lot of
effort because the time
frames, the schedule, etc.
And the kind of daily
distractions are so different.
And it's really hard to get those groups
together because when design is ready to
talk, production isn't and vice versa.
And I think those two groups are really
hard to get together.
But of course, it's really important.
We had the companies I worked in, we were
either I was either in a place where we
were right on top of production, like
literally in the mezzanine above the
production floor, which is really common,
at least where I'm from.
Drop things downstairs.
And that was important.
That was something I learned early on.
And then when we got to larger companies
where you might be
separated by miles or kilometres,
really organised points of
contact and events, I guess.
To drive that interaction
because it's so, so important.
And so one of my like,
what am I hitting at?
It's like, well, how much do you know, we
say we don't do
enough DFMEA in university.
How much PFMEA do we do?
And who does that?
Are you aware of anybody, I guess?
I haven't seen anyone doing PFMEA.
I'm I don't think I'm even aware of some
of anybody who's doing FMEA.
Yeah. Or if they are, it's
very lightly touched on.
So a corollary would be
we learn a lot of CAD.
Yes.
And who learns CAM?
Computer Aided Manufacturing.
Yeah.
There's some of it there, right?
Yes.
So we do we do a couple of weeks of it in
at this institution.
We do that in fourth year.
And then mechanical students.
That's kind of those two sides, right?
But it's but that's a very narrow aspect
of production, right?
Yeah, because you have nothing to do with
volume production or that.
In saying that, I mean, I did do a lot of
production engineering as
a design engineer, right?
Just because of the places I
worked and things like that.
And it was one of my favorite things to
do is to to go to generally Thailand to
go into the factory and to point out all
the things that they were doing wrong in
my view and how this is
going to be a problem.
This this is not something you've ever
gained any kind of joy
out of anywhere else.
No, no, of course not.
But it and there was, you know, another
again, look, I didn't even plan this to
talk about this, but there was my
diversity of experience where I was
versed in the production facilities in
Japan, and then we'll go into Thailand
and there are a lot of differences.
But I knew why certain things needed to
be aligned and why others didn't.
And so that diversity of opinion, you
know, you've got many, many dozens of
years of experience there in that
production facility.
But I know because my experience, what's
going to be a problem?
And I get to go in there and say, I know
you've been doing this for 20 years, but
you have to change this.
And here's the reason.
Anyway, and sometimes it's sometimes I go
back and do it again.
Fade to music.
What a great time that
was, though, honestly.
Yeah,
some people enjoy it.
Some people don't.
Yeah, I really enjoy it.
You know, it depends.
Yeah.
I again, I remember doing a time study
for an auto, an automotive supplier.
We're not talking
about whom or where or why.
And I said to the production engineer who
was in charge of the area, like, why does
that take three and a half
minutes to run a bead of glue?
And he's like, oh, we got
the top person in on that.
And I'm like, that's so slow.
Because I'd seen it done
in a different organization.
I'd done.
I'd seen something done very, very
similarly that was
done very more eloquently.
Yeah.
And I could actually add into that
because I'd seen
something very similar to that.
You've just struck on an interesting
aspect of production engineering, which
also involves design
engineering, but tact time.
Yes.
And what
is tact time?
Do you remember what it was called?
I mean, because I don't.
Yeah, it's like.
So the basic premise is that every single
operation has a specific time and you can
work out some things happen in parallel,
some things happen in series.
So one after the other concurrently.
And when something's happening in
parallel, those things that have to
happen in parallel, you need to have an
in the same sort of time frame or else
you end up with a bottleneck.
Yeah.
And that's what tact time is working out
is how long does something take and where
are your bottlenecks?
Where are the things
that take the extra time?
Basically in a factory, every time a
factory worker starts or repeats the
task, the interval between the
repetitions, you know, iteration one,
iteration two is that tact time.
And one of the greatest things I got to
do ever as a graduate engineer is spend
two weeks on the factory floor.
With a stopwatch?
No, no, no, doing the tasks.
Oh, cool.
So so, you know, we'd go in, we'd do like
a half hour at each
station sort of thing.
And so you work an eight hour day and you
do a half hour at each trying
to keep up with the tact time.
And only like I'll tell you,
it was quite something else.
If you cross thread the bolts when you're
fitting the bushing mounts for the
stabilizer bar on the
time to be like, you're out.
No, you have to fit within the tact time
and you have to back those bolts back
out, swap out from the socket to the tap,
re tap the hole with the same gun, take
the tap out, throw that in the bin of
bolts that you got there, grab another
bolt in the socket, find where you left
the socket and and drive the bolts.
Wow.
And, you know, I would like that was the
first station I ever worked on the one
I'm describing just there.
And so I would, you know, the person who
worked there would get would go really
fast for a while to get me right up to
the start, you know, and the other thing
is, you're like moving horizontally as
you're doing this because everything is
moving really, really slowly, but you've
got your little station,
your little boundaries on it.
And so I would start up at the front and
then buy like, I don't know, eight
iterations or something like that.
I was I was running into the
next person station, right?
And then the person who was overseeing my
work, whose station I was I was working
in, they would then get me back to the
front in about, you know, five or six
sort of goes, because they could work at
actually something like, you know, 80% or
70% of the attack time.
Yeah, attack time here, we're talking at
least a hono is in
the order of 45 seconds.
Yeah, it's fast.
And you are doing, you know, four or five
operations with, let's say, on the order
of nine to 10 fasteners
or something like that.
Yeah.
And inspecting a thing and then also
maybe torque checking something else that
somebody did up the line and then getting
the pen out and marking that like it's
it's it's it's it's why the demands on
factory workers are massive.
And but this is all to
make it profitable, right?
Correct.
And so you have to design a car.
This is my experience, not just that can
get down the road, not just that, you
know, is safe and doesn't fail and
doesn't rust and all these sorts of
things, but that somebody can manufacture
at an incredible pace.
Yes.
With using basic tools.
Now, this is something that I would
highly recommend to any person, whether
they be undergrad or
recent graduate, especially.
In fact, even someone as old as, oh,
well, maybe not as old as maybe it
definitely almost as old as you.
But if you get that opportunity, would
you agree that take it
like, oh, yeah, do the do this.
And even if it's only for two weeks,
like, you know, you find that your own
appreciation of what has to happen and go
into manufacturing skyrockets.
Yeah.
I mean, as a mechanical engineer, if
you're not seeking out those
opportunities, you
know, you really should.
Yeah.
I think I mentioned to you in the past
that, you know, before I was working in
the industry, as I was working through my
five years of degree, I worked at, among
other places, a
cigarette tube manufacturer.
And I still like remember every drum,
all, you know, 23 of them in a cigarette
manufacture machine.
We actually the factory I worked at, we
didn't actually manufacture cigarettes.
We manufactured cigarette tubes with the
filters included, but that there were
there was no tobacco in them.
Yeah.
But what an amazing time, you know, I
learned more about mechanical engineering
in that factory than I did throughout
five years of tuition, I think.
And I've worked factory lines.
You know, I grew up in
fruit growing country.
So you you are not a local if you haven't
worked at the local preserving company.
And there are two of them in the area.
And work at an old factory if you can,
because then you get to look at the cam
follower setups that do everything
instead of all these servo controls and
all that kind of stuff.
Now you're showing your
age, but they're fantastic.
I mean, if you don't get enjoyment of
that, again, like this
is what I'm getting at.
If you're studying mechanical engineering
and you don't find that fascinating,
maybe consider different disciplines.
Perhaps.
I would also point out that if you think
that engineering is or you think that the
right job for you is where you sit in an
office all day, don't do engineering.
Even though you probably will spend most
of your time in the office.
You'll spend a lot of time in the office,
but it should be one of those things that
you're going out and and seeing things
and looking at what's going in and around
you is really, really critical to your
growth as an engineer.
Cool.
That was a fun discussion.
It was.
I think we're done.
Now, I'm going to tell
you where we are today.
So we are currently in the Alan Finkel
building at Monash
University and we are in my office.
And I didn't think that we would be able
to cram everything we needed in here,
given that my office looks like a shovels
at the moment, but you've managed to make
it completely and
utterly, infinitely messier.
So thank you so much
for your time today, Mike.
No problem.
