pjm_, re collett holder ...make
yeah i'm probably heading towards that to be honest
i cant find any straight shank holders for them
only QC40 is it? the big quick change tooling from bridgeport CNC's
dunno all the modern stuff unless I look in the catalogues...then I get upset.... I want.....
I got another dividing head yesterday just contemplating 5th axis
pjm_, ot look at the tormach tooling see if the idea can the adapted
actually its a good idea to try to find a 'near enough' holder and get it turned out
tool post grinder if its near enough

someone here was setting up solar power, maybe of interest http://freshmeat.net/projects/solarcalc-22
hah, a 'blisk' is the impeller like blade disk in a turbine. heres 5 axis demo of it being milled (include stock removal and machine sim )

was talking to an ex Delcam worker yesterday
someone scored delcam & ug nx5 in thailand a couple months ago ;)
Delcam had/has 200 ish programmers... no wonder it costs!
the way 'step' works with such a blisk is shown here http://www.youtube.com/watch?v=S5DwlsGxwks
i think im starting to see how the same data is used by other machines.. metal removal, surface treatment & inspection machines.
of course i came across your worm gear vid too. you make custom disk cutters for that?
that was a standard form that happened to fit the job but I make cutters for jobs
it was interesting in that the way I write gcode, the standard cam progs dont think that way (they expect a solid model) I would have to got to APT etc
in this 'step-nc' solution for blisks, the hurdle is to find a toolpath and avoid collisions.
several machine used the same step data but required wildly different setups to avoid ....
corner of Z ram colliding with tilted B table clamp etc.
so an effort to build 'collision prediction' into cad begins, and, modeling machine tool and kins too. cool!
I like APT a lot, but you generate the surface to drive the tool across, thats pretty much a 'solid model'
no complaints, APT is very vey cool
oops laundry room run, bbl

So, what is a reasonable time of night to stop CNC machining? My lathe is facing down a square block of cast iron downstairs. I am monitoring progress aurally, and I assume the neighbours are too.
SWPadnos: wanna see a cool lil toy?
andypugh, if the police show up, it's too late
JymmmEMC, uh - maybe ... :)
Incidentally, G95 (cut per rev machining) looks to work in imperial on a metric lathe, or something...
andypugh: sounds fun :)
it should work fine
(unless there's a bug)
Should I actually measure it to make sure?
no, if it looks like inches then it's inches. the kind of error you could see (if there were bugs) would be more like getting mm when you expect inches
JymmmEMC, I've seen something like that before
in fact, I think Microsoft even makes one (strangely enough)
SWPadnos: for $40?
oh, probably not
Well, G95 F0.25 was advancing 6mm per rev. Of course I am not sure how well the rpms match demand, but then that shouldn't matter.
Unless it is picking up on the wrong track of the spindle encoder.
SWPadnos: I figure for a Q&D headache free NAS, not too shabby
SWPadnos: it says it can do usb cameras too
might be cool if it you could use a usb hub with it
Sorry about that, I managed to hit a duff key combo and close the browser
What I was saying was... I am trying to use G28.1 to write the current position to #5221, #5222 and #5223. It seems to work on sim-lathe up here, but down on the real machine, it doesn't.
Or does anyone know a better way to read the current axes?
Hmm 9:45pm is probably time to stop disturbing the neighbours. Back shortly.
OK, goodnight chaps
i needed a teeny vise and was looking at flytying vises... found a guy who used xacto knive handles,
he used a die to thread the handle 5/16 to make his workholders.
sorry, busy scratching around the pox :(
I hate these things
anybody know of a commercially avaliable CNC machine that is based on *nix?
for its imbedded operating system
I'm sure there are a few, although DOS is probably more common
I was at a machine tool trade show here in Portland Oregon last week before I got sick... seemed most of the controllers used windows XP
hopefully just the user interface
hard to tell without talking to somebody that was involved with its creation
there is a fairly strong commercial incentive to using XP
there is a real-time variant of windows that works fairly well
I wonder how soon soon opensource creeps in
I was thinking that if it was linux it might be easier to tweek
support is a nightmare if users tweak
it probably wouldn't be in the category of "tweak"
is there any cam software around for linux?
not a lot but there is some
[21:56:10] <archivist> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Cam
coming along is heekscan and heekscnc but its early stages
discussion of it is in #cam
WalterN: are you around Portland?
DanielFalck: I finally bought a torch, might make some frames soon
