The World of 1/100 Millimeter
The World of 1/100 Millimeter1:55
They
say
you
can't
build
what
you
can't
measure.
And
when
you
can
measure
things
really
precisely,
you
can
build
things
to
an
extraordinary
quality.
At,
Nissan,
they
have
developed
a
device
that
they
call
the
"3
Dimensional
Measurement
Machine"
to
detect
the
minutest
of
discrepancies
in
their
vehicles.

We
shine
the
slit
of
laser
light
that
comes
from
the
tip
of
the
3-Dimensional
Measurement
Machine
onto
the
object
we
want
to
measure,
and
scan
the
sectional
form
to
accurately
measure
every
detail
of
the
three-dimensional
form
and
convert
it
to
data.
The
secret
lies
in
the
shape
of
the
laser's
beam
of
light.
It's
not
a
point,
like
most
lasers
we
think
of,
but
a
slit
of
light
which
can
scan
a
whole
area
of
the
car
in
one
go.
If
two
seemingly
idetical
cars
are
measured
at
this
level,
their
differences
become
obvious.
For
example
it
checks
to
see
that
the
car
doors
will
fit
exactly
-and
we
mean
exactly-
down
to
1/100
millimeter.
Nozomi Iida Senior Engineer
By
taking
data
for
the
whole
surface,
we
really
know
it
down
to
the
details,
so
we
can,
for
example,
compare
the
actual
car
against
the
CAD
data
generated
at
the
design
stage,
and
find
out,
simply
and
specifically,
how
we
should
modify
that
part.
At,
Nissan,
surprisingly
precise
cars
are
developed
through
the
eye
of
a
laser
that
will
detect
the
difference
of
even
1/100millimeter.
Nozomi Iida Senior Engineer
By
manufacturing
each
individual
component
precisely
(using
the
3-Dimensional
Measurement
Machine),
we
can
make
good
components.
By
combining
those
good
components,
we
can
make
good
cars,
and
we
want
to
use
that
result
to
create
cars
of
high
performance,
quality
and
durability.
