quiet in here tonight
in IRC, no-one can hear you scream
I can't scream
too much yelling at the baseball games

lol @ jmkasunich
i am hoooome
american society of precision engineers, ty for having me
now you get to wear a scratchy iron ring?
I think that's a civil or mech eng thing
[02:25:36] <jmkasunich> http://en.wikipedia.org/wiki/Iron_Ring
canadian thing it seems
i finally met people crazier than i am!
what was the name of the machine that does surface profiles again?
the one that's "not a CMM"
oh, universal measuring machine
moore made them
now they've got different tools they use
like talysurf and white light surface interferometers
i still wish we had one of them
it came up the other day and i couldnt remember what it was called
vwippa vwippa slim shady
i am so glad the 90s are over
the 2000's are almost over
yeah but the 2000s have been okay
mostly because i completely zoned out of pop culture
yeah my idea of what happened this decade is wikipedia and google
this just sounds too unlikely to be real
"HoloVID is a tool originally developed for the holographic dimensional measurement of the internal isogrid webbing of the Delta Series of (launch vehicle) Space Craft skins by Dr. Jon Dark in 1981."
holographic measurement is michelson interferometry with a holographic standard rather than a reference mirror
or that's usually what it refers to
unless they are trying to actually TAKE a holograph
of the surface
and doing the metrology elsewhere
yes that makes sense, its just it sounds rather sci-fi
dont they have to take a hologram of a 'good' part in the first place?
the places that sell holographic references have all the crap to make a high quality master
and verify it
you get a little certification, just like a calibrated gage block
hm. reading about this makes my head hurt, so i think i'll stop
it's bizzare stuff
Anyone need a good youtube laugh?

1:30 into vid
the berlin fuck parade :D
was that a slight on the SAE?

Precision Engineers so the SAE mus tbe imprecise engineers?
precision engineers deal only with subsystems of larger designs
they don't actually design products, just very specific components and they also do the process design
for those components
some people fall more to one side than another
it's not really a dig against the sae/asme
just a very specialized group
automotive industries have like, zero use for precision engineering
it's more for like, lithography and optics
bizzare litho and optics
some biomedical crap
oh so measurement instruments would fall under it?
cmms and stuff, no
like, for instance
a freeform turning machine to make aspheric molds for cellphone camera lenses
and the measurement equipment to measure the mold and the finished optic
so interferometers would fall under?
but PE guys use them
microscoping molding applications
like, molding conductors onto a thin film to make a piezoactuator
any time you need to have a machine moving in nanometers, millionths, angstroms, etc
sounds like the nanotech/semiconductor stuff
they are big customers
because they understand their process and how to manipulate it
but they don't know how to go from something microscale and manipulate it from macroscale machinery
so PE dudes bridge that gap
Oh so the implanting and photo lith people would be just that?
not ALL lith
but like, lithographic heads
ion milling, etc
it is pretty cool
stuff that I've seen in schools
a lot of universities were there
some of them had machines they needed built and were asking around for quotes and components
were the guys who write IBM with atoms there?
someone was trying to put a C axis on a lithographic head
not that I saw?
someone was there measuring spindle error below the atomic level
they were using a crystal as a scale, and watching the atoms with a tunneling electron microscope
for sub-atom movement
that was about the only atomic manipulation i saw
and it wasn't really manipulation
i just want to meet the poor bastard who had to align the microscope head to the spindle axis
you can write IBM with just about any SEM though
or so I thought
it's got some function to pick atoms out of a crystal lattice and put them down somewhere else
they either worked for IBM or were funded by IBM
for electron traps
if you can find who it was i'd be interested in looking it up
the particulars, that is
let me see if I can find the page
[05:44:41] <ds2> http://www.almaden.ibm.com/vis/stm/atomo.html
that is such a cool microscope technology
i don't know anything about them though
all that makes lathes and mills look like work done with an axe
the coolest is the diamond freeform lathes
they can do molds and cavaties
they're like really high order multiaxis machines that don't clearly turn or mill
just move the tool over the profile
