febisfebi: to change the pins you have to recompile
yeah, i know
thtas why emc2 got started ;)
argh .. too much wine
and its late
hm, I am hand writing this program..
stupid cam program that cant generate arcs instead of lines.
2d or 3d?
[00:26:38] <anonimasu> http://www.bojn.net/~an0n/part01.JPG
you have an .stl file?
I think I can export one
iges I always have trouble with ... so many formats
argh ,.. to much wine, i could try and feed it throuhg a cam package but its gone midnight and im a bit ...
whats the word?
I wish I were like that also
I got a stl now
you just want it machining away, in the red shaded bit?
cutter dia and depth per pass
50% of cutter dia
I am machining plastic :)
the main problem is probably me & my cam package.. :)
the stock is somthing like 70x100
thats a lott
to machine away
part os 60x60
* robin_sz cant type :)
yeah but I just cut a test piece of the plastic..
it's to be machined out..
err contoured out of the platic piece
so I use 60x60 as the stock
damn it wantd
to cut thods
want me to remove them?
lets see if the code works first
and mail you it again?ok
ballmill not flat
bah, should be the same
my mailserver is a bit slow on incomming
since it scans everything :)
damn .. and 12mm ... wait 1
way too much wine!
thats just a roughing pass, want a finish pass with same cutter?
heh, your influencing me to make typos too
this is for 60x60 stock, it will try and finish the outside ...
I forget exactly what post htis is now ... shuld be close though
just finished my diamond sharpening jig after a long day
and does it sharpen your diamonds nicely?
nope...will true the wheel tommorow
I made an arbor accurate enough that I will not have to retrue after breaking setup
couple tenths runout
.005 mm tir
To get that I must align the collet to a radial mark each time
so it goes in exactly the same
robin_sz: I'll try it in like 2 minutes
still has the plunges for the edge chamfers
I am just simulating yet
you have grpahical viewer?
emc + backplot
it's the machining time that I am looking at
what did I set as feeds?
I need it to make the o with arcs to get it smooth..
random I suspect
or well smooth/fast..
the trouble is that cam packages break stuff like that up in lines..
perl -pi -e's/F0.6/Fxxx/' foo.txt
emc2 dosent have segmentqueue or does it?
should be fine in segments or arcs really
or what it's called :)
* robin_sz has no eyed deer
hmmm checking my email I see I have a request for an acoustics consulting gig
another portable power tool silencing job no doubt
here, have some pseudo random fan blade spacing ;)
well this is Paslode...an ITW division
I cansee that could be fun
hmmm I am a muffler designer again?
plenty of oportunity for using casings as mufflers
my code works great now also ^_^
I found out how to mill it with in arcs
I'll try the one that you sent me too :)
the pices are supposed to take like 5 minutes each
I gave up hand coding years ago ...
oh I dont hand code ;)
I feel the same..
I should read back...but what are you making?
and tooling parts
a housing for a tree seed planting device..
this one I am trying to machine is the first prototype..
I hope to have a bit more of that kind of thing after turkey season
we are going to market em with the other stuff we make for making the holes to put the seed in ;)
I had better...I hired a retired engineer part time for the machine tool end
yeah use those cheap super PLCs
they are expensive but very good..
but well they do multitasking and stuff like that..
$200....pid servo....stepper... lots of analog and digital io....progams in basic and ladder
10 amp 24v outputs
programming this in ladder wont cut it :)
I am using that for the spray painting robot
yeah but you dont have 2 chnnels to control..
it's more like 2 robots.. with sensors and stuff..
that's running in paralell on the same plc..
same here...that is why I like the ones that progam in a language
the ones I work with is in some C-ish language..
Basic is not the best...but it will do nicely
it does c++/c also ;)
or any language that can give a .coff
I have to review basic a little...have not written in it in many years
I wouldnt enjoy writing this in basic..
it's too much stuff..
let's see...instead of switch() it's case_select()
user interfaces and stuff also.. and serial port interface for the PC in the machine's they mount on ;)
robin_sz: you have the same problem with that program that I had with mine earlier
yeah this one I am using is rs-232 and 485
well I have bugged you enough...off to the music room for a few tunes
Miles and jimi hendrix?
I am listening to infected mushroom..
keeping my brain spinning..
I am dead tired..
me too..took 12 hrs to make that grinding fixture
that beats what I've done today :)
I am looking forward to hearing how it works
Had to do it...I am 6 or so hours from having no sharp cutters
But sharpening carbide spiral end mills will be good
I think I got myself into some trouble today also..
a friend asked if I could machine some gears off a gearbox shaft..
but I think that will go well :)
machining the teeth?
turning them away..
in the lathe :)
All the stuff I made today was 1140 prehard
machines nice though
I cant relate to how hard that is
is that brinell?
rockwell c 30 or so
also known by the trade name "fatigueproof"
used a lot in car transmissions
has a very good machinability rating
80% or so
pretty amazing for something that hard
Get some...you'll love it
oh it's not that hard..
I machined some 300 brinell hardox on my small mill
C35 is 331 brinell
hardened hyoeutechtoid steel that machines like butter
c30 is 285 brinell
although it depends on how sharp cutter you have :)
I just tried it, the metal got all shiny afterwards..
Machined with cemented carbide
I wish I had a good source for stuff like that
my supplier is limited..
but I can get stainless and alu now
hard turning is cool...5 times the efficiency of grinding
single point machining of hardened materials
I've never heard about it..
with carbide or polycrystalline diamond
I have loads of SECO carbide inserts..
that I bought off a auction..
I use either c2 carbide or M43 cobalt for most stuff
I love the questions on cnczone on how to make holes in carbide..
with the effort it requires it'd probably be cheaper to have somone edm them
yeah I guess
I am looking at my diamond cleaning stick...
It opens the grain after truing
its aluminum oxide
seems strange to use that for cleaning
I guess it abrades away the resinoid binder
but does not dull the diamond grains
that sounds right
Seems reasonable I guess...I have used the same diamond point to true aluminum oxise wheels on the surface grinder for years
I wish I had s surace grinder..
you can take loads off with a dimaond point too.
I found one at a auction for 25$..
They are handy
but it was too much work..
I used mine a bit today
first time in months
but when you need them you need them
I'd love to be able to grind steel pices..
nice little cylindrical grinder is nice if you get one
little myford ot the like
I have two themac tool post grinders for the lathe
like jaws for vises and stuff..
I rescraped the surface grinder with a lab grade surface plate
so it is very accurate
put a ground part on the plate and the indicator doesn't move
i like my lathe too much touse a toolpost grinder
I just tape polythene all aroung the ways
how do you keep it out of the coolant?
cover everything up
I'll be sending my mill table for surface grinding later
I grind dry
I just need more toolmarks into it ;)
but they are slow....01 mm is a DEEP cut for them
surface grinders or toolpost grinders?
turning first and then grinding :) is a good way to make it quickly..
today on the surface grinder I was using .06 mm roughing cuts
then spark off at .005 mm
I used the new norton type 32 hybrid ceramic wheels
They are very nice
robin_sz: that program is still running
I will not buy anymore pink or white wheels
at 0.6" minute im not suprised
oh I am running at 500mm/min
delete all the F words! :)
* anonimasu yawns
me too...hey wasn't I going to the music room?
yeah you were
well I shall
I'll be heading for the shower..
I'll finish this program tomorrow
I hope I dont fall asleep and drown
it's 02:47 over here
robin_sz: thanks for the help!
robin - recovered from the wine?
well the diamond carbide grinding setup is working pretty well
the diamond cup wheel goes through c2 carbide like butter
The moh hardness scale is obviously not linear
I've been having trouble with emc today
and the aluminum oxide cleaning stick works well
I get loads of ferrors
I have my min_ferror set to 0.01 and max_ferror to 1
I have mine set so tight that if I start in the morning before the shop is heated up it will estop
but when I accelerate over 500mm/min it gets joint following error
servo or stepper?
geckos with servos..
the ferror is just a virtual thing
put in big numbers
the most I'll ever have are +/- 128 counts..
right...the gecko controls ferror estop...not emc
so I can just ignore it and put my ferror high..
is that right?
emc numbers are just for the virtual software servo model
They have no real physical significance
the machine moves at 1000mm/min without problems it just ferrors pretty quickly..
just like that...
I'll be getting a vital card later on but I need to do some more work on the machine to justify the purchase
Only in full servo mode do the emc ferror numbers do anything
I will use the vital on the second mill coming in
I'll wait for my purchase until you've been testing it for a bit ;)
I think g2002 seems nice also..
but I like having the feedback like on real machines..
well buddy, the guy near me, got it to work fine on a real machine
so i'm ready
all I need is time
I dont care much for the money.. I've already invested too much to care
I called and will have so engineering to do in march
what kind of?
It's for ITW Ransburg/Gema
that seems cool
The inventors of Powder coating
Robin would like that
hehe yeah :)
well if that's the case with ferror I might be able to machine theese parts tomorrow
We need to develop a method to compete with Graco's air turbine generator that develops high voltage from the air supply
I am going to try a whistle!
I've never heard about air turbine generators :)
ultrasonic Piezo reed vibrates in a supersonic air jet...
shuold be challenging
need to make about 6 watts
with a whistle
hm, that's not that much..
or is it if we are talking about generating..
I remember dog whistle sounds could be concentrated with a parabolic dish to light little fires like a magnifying glass
or rather violent.. :)
so 6 watts might not be a big deal
yeah if you can use somthing like that
trouble is I must spend some time in Chicago and Indy
somthing like whistle > dish > to collector mounted on whistle
I charge $1000 a day for plant visits so I think I will survive
or somthing like that :)
cant really complain with that salary :)
not sure...might be a dirctly vibrating reed or a helmholtz resonator coupled to the piezo
but I won't think about it too much...
till the development contract is signed
yeah it's best that way
I get half manic when building stuff..
I need money when I am hurting my brain thinking and stuff
I think about the stuff I do until I forget other things that's less nescessary
hmm I was thinking if taking a month off in the spring
yeah you should :)
I need it
I was supposed to be in brazil last week and this week.. but my mother got ill so we couldnt go
The first spring flowers are blooming now
Ah Brazil...warm there
it's -27c outside over here
oh the first flowers often get snowed on
It got that cold in Chicago
but -27 is really cold
time to frostbite for unprotected skin is a minute or two i'll bet
might be over there
I was expecting it to be around 40 somtime soon
The coldest we get here (up north) is in the -40 range
c or f...doesn't matter
the scales cross there
I like cold weather
The record for here in Georgia is -16f
how many c is that I never remember how to calc that
about -30 c?
over -17 is pretty cold to be outside in
yes that is below zero on f scale I think
or around zero
Oh...one thing I found about grinding carbide...
the dust is not a big problem
Carbide is so dense it just falls right down next to the wheel
does not float around and get on stuff
I took some pictures...I will put them on the blog later
that's nice :)
Well, I must go to town and get groceries. I am totally out of everything
yeah do that
not even a cracker to eat
ouch that's really bad
just too busy
be back on later
I'll be heading for bed in a couple of minutes
* anonimasu goes *pong*
* robin_sz holds his nose
less drunk today?
yeah, but tired
hows your tree planter?
it's going nicely
got emc to run with my toolpaths and all..
but I get ferrors..
thats servos for you :)
oh, it's emc that think servos..
I have geckos so I'll never be more then +/- 128 counts
ah, yes thatweirdness where emc pretends has servos for steppers
need faster PC then
it's a 500mhz..
it should be plenty
I would have hoped so
what frq are you trying to get out of it?
640pulses per mm
x mm per second
so 10.6666 khz
that seems low somehow..
sounds not too bad for a 500mhz box
isnt that hz..
or if it khz?
howdy guys :)
I said khz
um that's low..
I ran 25000hz with turbocnc..
robin_sz : I think my clymer manual has an error
isnt turbocnc pretty much set freq?
as in it will achieve this rate under normal conditions?
nevermind I was under the idea that it would do a higher rate for some reason
oh it can...
but I ran it at a p200mmz
hmm, I guess I'll have to set the multiplier on the geckos even more
but that'd give me a stepsize of 0.0125mm..
robin - had any time to play?
but not in depth
recovered from the wine?
yeah, just the swiss to deal with today
*supposed* to be going to geneva on friday ... but still beating software into shape
ecch - good luck
remember there's always one more bug
1? hell .. I have plenty :)
of course, the client has no spec, so its hard to deifne bugs and features ;)
Ahh yes - the mind spec
