<Noxz>
any press is a decent example of perpendicularity though
<Noxz>
not exactly sure how to make it about MEMS, but there are of course multi-objects that need assembly somehow, and you would want to apply even pressure
<mrdata>
pricey
<Noxz>
for the press? it actually doesnt look high priced to me
<Noxz>
well worth that money
<Noxz>
especially with all of the bits given
<Noxz>
to me, at least
<mrdata>
depends how much you use it
<mrdata>
if a thing pays for itself in 3 uses, it's pretty good
<Noxz>
sure, anytime you set/replace a jewel (is the main purpose, though there are other similar tools, like a staking press for other similar actions)
<Noxz>
I don't think you can really attach some arbitrary number on a tool like that..
<Noxz>
typically at work we would say: if you are manually doing a task 3+ times, it's time to write a script to automate it
<Noxz>
but even then might be a stretch
<Noxz>
it depends more than just volume
<Noxz>
but that could be a big push

Noxz: that press is probably not very perpendicular
<Noxz>
considering how interchangable it is, not
<Noxz>
but how accurate should it be?
<sync>
within a degree or two will probably do
<Noxz>
sure, but it was still the idea of how does one make something perpendicular
<Noxz>
and I have thought of the way, essentially using an optical flat
<Noxz>
ie, drill the hole, insert a true flat cylinder, and lap the bottom it would press onto
<Noxz>
to be parallel with the cylinder blank
<Noxz>
then yoou can worry about leveling the actual tool to ground if you so wish
<sync>
wut
<Noxz>
drill the hole and bore it, yeah?
<Noxz>
insert a cylinder for that size that is flat/perpendicular
<sync>
I don't see where th optical flat is involved
<Noxz>
and lap the mating bottom section f the tool that the cylinder would come in contact with
<Noxz>
and use an ptical flat to detect paralell+flatness with the cylinder blank
<Noxz>
you want parallelism
<Noxz>
right?
<Noxz>
for perfect mating
<sync>
I'm not sure what you want to do but I'll say yes
<Noxz>
in the end it's just a (manual) press
<sync>
just bore a hole through the colum and be done
<sync>
+n
<Noxz>
but how do you know it is perp to the flat surface that your collets go into
<sync>
doesn't matter
<sync>
if you bored through
<Noxz>
what if it did?
<sync>
it cannot matter
<Noxz>
which column are we talking about
<sync>
as the axis of the bore is the same
<Noxz>
there is an upper and a lower
<sync>
yeah, which is why you bore through both
<Noxz>
I am saying drill a hole in the upper
<Noxz>
Isuppose doing the lower owuld work as well, for then mounting.. a perpendicular... resting tool or similar

I just dont have any real experience as to how perps ar epreciscion made, untill somewhat recently of looking it up
<Noxz>
it was more a question as to how its dont, and an exercise in my head
<sync>
it all depends on what you want in the end, I'd face the casting on the bottom, drill the upper hole, put the upper hole onto some cylinder and then bore the bottom
<sync>
if the alignment is critical one would bore in one setup
<sync>
and then align it to the axis of the bore
<sync>
perpendicularity is always made by the precision of the machine
<sync>
read moores foundation of mechanical accuracy
<Noxz>
well, not from what I looked up
<Noxz>
you basically mate them
<sync>
nobody has time for that
<Noxz>
you have to start with one true/flat surface, sure
<Noxz>
heh, well, machine shops do it
<Noxz>
they charge for it
<sync>
no
<Noxz>
but it can be done
<Noxz>
we're not talking about mass production here
<sync>
stuff like that is used in mass production
<sync>
and nobody is really hand fitting anything there
<Noxz>
alright, then why 'no' ?
<Noxz>
hrm
<sync>
µm precision/accuracy is stuff that people need and make on a daily basis
<sync>
and the basic geometry is supplied by the machine
<sync>
sure you can handfit stuff but that is not what most people want
<Noxz>
but the point is that you start out with some flat/parallel surface
<Noxz>
what I did in my head was drill first then make the mating surface flat/parallel
<sync>
at first you need to establish a datum
<Noxz>
iunno.. I want to try some stuff out, that's all I know
<sync>
which will be the foot
<sync>
and then it is up to the tolerances you get
<Noxz>
but it doesnt have to be, because then you need to set that parallel with your machine
<Noxz>
and hope your machine is perp
<sync>
how do I clamp an uneven surface?
<Noxz>
but, my drill press is just a simple mortisser for wood (who knows what metal it can do) and I am sure it is not very accurate
<Noxz>
iunno... how do you? ;)
<sync>
mill it flat and then actually have something to mount your part
