After the birthday tribute to the British and Commonwealth Monarch, this web-log returns to the previous focus upon the manufacturing element of the automotive corporate dynasty.
As a young woman within wartime Princess Elizabeth played her part by mending and driving ambulances, in a period when those of both genders with curiosity and aptitude could themselves add-value. From the drafting boards of aeroplane producers to the factories of equipment makers to the repair and logistics of the transport corps. People recognised the value of constructing and repairing goods within a very pertenant atmosphere of simultaneous prolific output and a 'make do and mend'.
Today we still sit in the fall-out of the 2008 financial crisis, and many have had to utilise a similar personal philosophy. But with it comes a sense of personal interaction with the technicality of things that surround us, and with it again a returned curiosity as to how things are produced, and with that a sense of self-empowerment and improvement as not just unquestioning consumers but with more knowledge and discernment, and with the ecological impetus, a new era of design and build which requires increasingly engaged, proactive participants.

Given the role of the car today, it might be unsurprising if the notion and social idiom of the manufacturing process is exemplified by the vehicle factory; with the consecutive build-process seen in their 'mind's eye' as representative of modern manufacturing; even if unfamiliar with the processes that form the component parts.
This thanks to of the decades of news reports regards the closing or opening of car factories so effecting local and national economies, as well as the myriad of documentaries produced. These span from Pathé News items for 1930s cinema through to latter-day efforts such as National Geographic's 'Mega-Factories' series and onto today's era of amateur video uploads.

The very experience of
production has now become an increasingly engrained part of the
culture industry, best exemplified by the plethora of Visitor's
Centres, such as Cadbury's legendary Bourneville site for chocolate
and confectionaries, through to replication of this approach by old
family regional beer breweries, themselves seeking to re-invent and
expand aspects of their own businesses. Within autos, it is now
almost standard practice to welcome in the public, from the massive
Volkswagen AG in Wolfsburg, to the relatively minuscule Morgan Motors
Company in Malvern Link, all providing guided tours of the production
process so as to engage owners, potential buyers, the public en mass
and tomorrow's engineers. Perhaps the present philosophical pinnacle
of this fascination seen at FerrariWorld in Abu Dhabi, with mock
replication of portions of its Modena facilities accompanied by real
video-screen footage.
Thus even production
has become a 'hyper-real' product to sell to ever more inquisitive
and voracious consumers of 'experiences'.
Yet just as this public
fascination with production has expanded to enter the public sphere,
so at the 'back-end' driven by ever mounting PESTEL demands, the very
realm of automotive manufacturing has had to adapt, continue on an
evolutionary path and even radically revolutionise.
So where as for decades
the likes of GM, Ford, Austin or FIAT could create a a near direct
like for like new facility anywhere in the world, today the various
local demands mean that far more than production capacity must be
considered. With the EM factories of today necessarily
'future-proofed' for the ecological requirements of tomorrow, using
AM plants as ever more complex guiding templates of sustainability.
Manufacturing:
The word
'manufacturing; originates from the idea of 'manual factoring',
whereby the output of a single craftsman was typically simplified and
amplified to increase the per item output. Or as likely the task
multiplied amongst many to likewise increase output. Typically
however, both simplified and multiplied so as to gain maximum
efficiencies.
This approach has
underpinned the manufacturing mentality the Ancient Egyptians, was
evolved as a regimented method during the Anglo-Saxon Crafts-Guilds
of the Middle Ages (a multitude of Apprentices' simple works mated to
that of the master Craftsmens' complex works) and obviously
determined as a yet more thorough discipline after the Industrial
Revolution.
Efficiency gains had
been achieved from common sense approaches centuries earlier thanks
to the influence of militaristic principles, but it was adoption of
the 'scientific approach' espoused from the earlier Enlightenment Era
that began to question all aspects of “manual-factoring”.
With the arrival of
'Big Industry' and the need to find ever greater productivity gains,
as part of management science, came the mid 20th century
'Time and Motion' man, studying every aspect of a process to reduce
wasteful time and effort, both in man and machinery. It was after
this period, during the 1970s onward, that the key issues of Layout,
Processes and Ergonomics started to be considered in earnest as the
man-machine interface was refined ever more.
As with every
industrial sector, the prescription of a specific manufacturing
approach and the methods used – primarily the type of 'plant'
installed and staffing levels/skills required - is typically
determined by the overall business case.
The multi-various
templates of today spanning:
1. “Mass” (250k
units to 1,000k units: ie Toyota, VW, Ford, GM, FCA, et al)
2. “Mid” (7k units
to 250k units: Rolls-Royce, Aston-Martin, Ferrari at the lower end,
Bentley and AMG in the middle and Jaguar at the upper end)
3. “Niche” (up to
7k units: Morgan Motors at the lower end, McLaren Cars in the
middle).
[NB It must be noted
that whereas once these three general categories were because of
specific manufacturing templates very separate, over the last 20
years there has been a concerted effort to necessarily blur the
boundaries of niche, mid and mass; these now ever looser terms.
This done to service
ever greater demand for specialist vehicles, as seen by Ferrari's
growth from below 5k units a decade ago to new ambition of 12k for
near future. And Jaguar's growth path from about 50k units at its low
point to expectation of well over 250k into the future.
The need to create new
product types to fulfil new segments at higher volumes using
lightweight materials, notably aluminium prompted a wholesale
transformation of Mid capacity production whereby the yesteryear very
separate techniques related to Niche and Mass have been entwined and
re-invented].
From initially the
labour intensive, somewhat haphazard and quality variable
“niche-built” operation (depending upon funding, staff
capabilities and build-time), thereafter to a “scaled-up” version
providing marginal to large cost savings (the bulk-buying of
materials and labour costs savings dependent upon a balance of input
costs and output numbers) and by the “mass-manufactured”, whereby
the potential of much enlarged scale and the introduction of advanced
new methods allowed per unit costs to be reduced significantly,
dimensional tolerances to be maintained and so quality to be
improved.
'Manufacturing
Engineering' relates to the design and build of those separate yet
well co-ordinated items of 'plant'; ranging in complexity, size and
cost; the manufacturing route determined by the nature of the
product, the business's innate capabilities, budget and volume
capacity sought.
However, since
auto-manufacturing has typically been scale driven since the 1920s to
this day for major VMs. With standardised American methods instilled
relatively early on, there was little need for major advancements
within the mass arena.
That watershed
contribution was Edward G Budd's pressed-steel process creating the
weldable all-steel body (initially for the Dodge Brothers) has long
been overshadowed by the story of Henry Ford's compartmentalised
production process. The former gave a massive contribution of cost
savings efficiencies to the latter.
Indeed the massive
costs of associated capital expenditure and entrenchment of the
pressed steel systems meant that general advancement in manufacturing
engineering was within its own sphere and with little transformative
pressures somewhat limited for decades; simply refinement of the
standard.
However, competitive
and regulatory demands of the present and future has over the last 20
years added far greater impetus for paradigm evolution.
One example of such
innovation being that of “hydro-forming”, an evolution of the
omnipresent press-type process using water and lubricant within the
'male' and 'female' parts of the tool to provide better finish to the
panel, greater curvature subtlety and better specific panel or part
strength. This seen with the chassis frame-rails of the Ford F-Series
and elements of the new Chevrolet Corvette.
Manufacturing
Engineering has then evolved to research, discover and offer an
increasing broad mixed-bag of solutions relative to the 3 capacity
templates: 'Niche', 'Mid' and 'Mass'. Each solution very much
dependent upon the right balance for the business case, as per
product performance, quality expectations, speed to market and
overall project cost.
As seen, given its
importance to many nation's economic agendas, for much of the 20th
century the external PESTEL influences on the Budd mass manufacturing
system were effectively benign. Post WW1 globalisation consisted of
exporting the idea of the American Dream via its consumer durables,
cars the most potent symbol of success.
During temporarily
changed circumstances adaptions could be made; material shortages
during wartime which could be substituted by other 'stand-in'
materials, and any short lived politically emerged oil crisis could
be overcome by making available and building smaller, lighter
vehicles, as seen in the mid 1970s. Thereafter, with strong peacetime
economies and the availability of plentiful, affordable oil
re-generating consumer and business demand for larger, heavier
vehicles (albeit with more efficient drive-trains and so maintained /
improved fuel consumption), it seemed that the Budd pressed-steel
system was destined to be all pervasive forever. And given its
irrefutable scale and global dominance that still appears the case
today.
However, as seen, since
The Kyoto Summit of 1992 there has been increasing recognition of the
need for a fundamental shift in attitude regards the vehicles of
today and tomorrow. That philosophical re-orientation has required
major manufacturers to re-think product specifications, use of hybrid
power-plants and critically the use of advanced materials and thus
the manufacturing methods by which tomorrow's new generation vehicles
should be built.
Audi's initial marriage
of the Budd system with pressed aluminium in the original A2 was a
major leap forward presaging the aluminium bodies of others from
Jaguar to Aston-Martin to Rolls-Royce.
This need to plan ahead
has then led to greater manufacturing engineering advancement by
certain quarters of the auto-sector within the last 20 years, and
specifically last 10 years, than seen in the previous six decades;
BMW's i3 the most advanced.
As with the product
itself, to assist with speed, quality, and cost, Engineering
Manufacturing has since the mid 1970s increasingly relied upon CAE
(Computuer Aided Engineering) via CAD-CAM to ensure improved product
exactitude, speedier development times and critically a closer
dialogue and parallel between product and manufacturing engineering
functions.
Whether that be for
exacting zero-defect quality control of a million-series run of a
stock component item, or regards a singularly CAE designed but
hand-assembled supercar, through to today's ability to create a
bespoke 3-D printed component. perhaps for the mechanical refit of a
long defunct vehicle sitting within a car museum.
'Manufacturing
Facilities' simplistically typically refers to location and activity
of a manufacturing 'plant' or 'plants', by which the finished article
– whether that be small trim clip or complete vehicle - is
produced.
As explained, for whole
vehicles this ranges across a wide arena – referred to as: 'niche',
'mid' and 'mass' production; though (as shown) 'mid' has become a
very loose definition.
This then spans
everything from a simple table-top jig at Morgan Motors for the
hand-bending of laminated ash (plywood) for the part known as the
'wheel-house inner', to an armature in Lamborghini's 'trim shop' upon
which a dashboard sits for hand 'dressing', to a major producer's
heavy panel presses and their inter-changeable dies for forming sheet
steel / sheet aluminium, to programmable, semi-intelligent,
multi-tasking robots that streamline the overall process, to today's
notion of batch-specific 3-D printed parts.
A massively wide
spectrum. all of which depending upon need and affordability,
configure and so comprise the various archetypes of production line.
Furthermore, as the
petrol/diesel engine becomes increasingly accompanied by Hybrids,
PHEVs and EVs, so the complexities of mid to long-term power
solutions raises important questions about the type of
technology-aligned production facilities will be needed.
In turn, this raises
questions regards the very industrial base and structure of the
industry.
Given the very scale
and level of global inter-connectivity of processes and indeed
corporate interests, a wholesale restructure of sector and associated
facilities is still a low probability outcome over the next two
decades, especially so in what could be an era of protracted 'cheap
oil'.
The rational
evolutionary step is not toward all electric EVs (except in specific
circumstances) , but the broader adoption of Hybrid solutions, with
adapted ICE as part of that mass appeal journey. This the best fit
answer to match consumer expectations of flexibility and range as set
by the internal combustion engine for over 100 years.
This common-sense
answer was understood by Toyota engineers and executives by the early
1990s, with the Japanese launch of Toyota's Prius in 1997 paving the
way for worldwide understanding of Hybrid's multi-fold advantages.
Prius thereafter re-set the landscape regards mass -manufacturer's
recognition of needing to serve the ecological agenda beyond
America's increasingly outdated CAFE regulations, the Euro5/6/7
efforts pushing intermediary targets, but each recognising it needed
various technical strategy routes to emissions reduction; to both
stay ahead of regulators and to deploy that strength as a market
advantage.
This need has been the
prime driving force in re-shaping manufacturing processes.
Whether the previously
seen reactive focus on the conventional combustion engine, typically
that of a smaller capacities and turbo-charging to maintain power and
torque and increased use of aluminium, plastics and even exotic
ceramics in families of proprietary engines....to the now widespread
inclusion of 'start-stop' flywheel ancilleries (incorrectly marketed
as 'mild hybrids'), to the integration of true series and parallel
hybrid systems to likewise that of 'plug-in' PHEV charging
sub-systems...to body structure 'lightweighting' through use of
lighter steels, aluminium, other alloys and composites...to expansion
of hybrid solution with the 'plug-in' PHEV...through to ongoing
experimentation with all-electric EVs as circumstances allow.
However, most are still
effectively testing the waters with EVs, so whilst the likes of
sector disruptor Tesla continues to plan and build its own battery
'Gigafactory', the established players will continue to prefer to
refine the ICE and for hybrid vehicles buy-in of battery systems from
the likes of Samsung and LG for what are in comparison to ICE lower
volume hybrid numbers and the very small number of EVs. Taking
partnership stakes as volume and business case circumstances dictate.
This because quite
obviously most prescient for the discipline of Manufacturing
Facilities, is a primary interest in the balancing of investment and
operational costs over a given time-scale, to make the venture
profitable.
Many issues are
included in this business equation, from government incentives to
domestic market demand to foreign export costs, the factory formula
typically governed by the two over-riding operational and cost
considerations of location logistics and labour rates. Getting the
mix right is crucial.
Simplistically those
geographies with high labour costs or operating as true
mass-manufacturing centres producing many thousands of units will
obviously encourage greater use of automation (ie 'robotic'
machinery) with fewer better paid skilled operators.
Whilst conversely,
low-labour cost locations will encourage use of a flexible low-skill
human workforce for the undertaking of manually intensive processes.
Thus mid-cost locations
typically require a mix of partially automated machinery and
semi-skilled people, even here the undertaking of CapEx to toward
robotisation seen as positive to drive down workforce numbers, the
general overhead and so per unit costs.
However, other factors
must be considered.
Such as the complexity
of the product and so need to be in close proximity to the
design-engineers, to the mass of the product and so its shipping
costs, to the overall corporate attitude toward the social care
toward its employees.
Often the more
technically advanced the product and its manufacturing process, and
the more socially conscientious the firm, the greater the likelihood
to be manufacture 'at home', those high costs absorbed by the strong
margin to be had from selling a world-class product, whether a BMW i3
or McLaren 675LT.
Whereas, any simply
constructed and assembled product may be produced in a relatively
rudimentary factory space, with little capital expenditure given what
may be second-hand tooling bought cheaply, and very short-term or
even day-rate labour force to match what may be a variable order
book. The fringe firms of the very niche sportscar and 'replica
classics' realm known to necessarily undertake this approach; as with
TVR's migration to Russia and AC Cars build relocation to Malta in
2007. Yet given the instability of demand, the fragility of the
business case, poor local infrastructure etc, this seemingly logical
production route can be fraught with problems.
Between these two
extremes is the mixed model, whereby stable demand for a product
allows for a new factory to be set-up using proven tooling and
quality processes. This may be achieved at relatively low cost often
thanks to the 'lift and shift' of part-used equipment from its
previous homeland base. This often a next step from previous CKD
local builds. (eg South Africa: Volkswagen 1950s on, Land Rover
Defender 1980s on, BMW 3-series 1990s on). Importantly, with positive
governmental policies, this initial arrangement can flourish to
create strong regional automotive sectors attracting more entrants,
as with S.Africa's 'MIDP' scheme.
Thus getting the
business balance right regards manufacturing facilities, given its
impact on product, people and corporate reputation is vital, once
invested, typically ordained for the long-haul; as exemplified by
Japan's FDI approach for its international satellite factories.
And as of today, from a
facilities perspective, it is somewhat ironic that whilst Toyota in
the 1930s moved up rapidly up the added-value curve by shifting from
the textile loom to the pressed-steel truck and car, so in the 2010s,
BMW has monumentally moved up further up the added-value curve by
defining eco-solutions through the loom weaving of carbon-fibre for
i3, i8 and expectant i5.
Thus all in all, it is
increasingly understood that the ever growing complexity of the
global auto-industry – as seen through the various lenses of:
product type and associated brand values, producer ambitions,
producer numbers, competitive actions, regulatory demands etc – has
inevitably meant a proliferation in manufacturing templates because
of increasingly apt technical needs and so dedicated production
process.
That said, whilst the
Advanced Triad regions continually modify and revolutionise their
product offerings and so manufacturing bases in the 21st
century – so as to lead the world - Emerging Nations across Asia,
Latin America and Africa will inevitably continue to base their
economies on the internal adoption of the proven lower cost
'old-tech' automotive technologies of the 20th century.
This means being oil propelled with much improved emissions,
steel-bodied, made in local factories (sub-systems likewise),
launched at publicly exciting auto-shows, viewed at local
dealerships, increased professionalism of Sales and Service, ever
growing used-vehicle markets and the need to adopt the progressive
materials separation recycling techniques at end-of-life. Indeed, by
thinking ahead, various EM countries may seek to demonstrate
themselves additionally as the consummate re-cyclers in their
'auto-age', taking the previous skills of basic necessity and
redeploying them as a new re-manufacturing capability.
Thus the industry
entrenched press-metal process (as created by Budd and demonised as
the heart of 'Fordism') is here to stay, and rightly so to mobilise
the global masses. Yet, because of the available advantages, it can
only be assumed that decades into the future it too will be mass
conjoined in volume terms to the carbon-fibre loom process.
At that distant point,
with most automobiles based upon a truly recognisable carbon
structure, it possibly means that auto mass manufacture could create
true global “carbon neutrality”. Instead of being viewed as the
problem, as is the seemingly the case today, the automobile and its
manufacturing systems, could be seen as a major contributor to the
ecological solution.
