#garfield Calendar
12:00 AM rue_shop3: yea, the one controlled by the pot
12:03 AM Tom_L: that's on the door
12:03 AM Tom_L: i disconnected the pot
12:03 AM rue_shop3: yea
12:03 AM Tom_L: and ran that to a dac on the mesa card
12:03 AM rue_shop3: "well you shouldn't have disconnected it, you should have made it a volume control for the motor"
12:03 AM rue_shop3: I'd just leave mine at 0
12:03 AM Tom_L: that's the orange and yellow wire there
12:03 AM Tom_L: if i flip the on off swithch off, it drives the PID nuts
12:03 AM rue_shop3: yea
12:03 AM Tom_L: i blew a fuse once when i realized it because it tried to go full bore
12:03 AM rue_shop3: there is another item on my todo list, to hack one of the brushless motors I have for the new cnc machine
12:03 AM Tom_L: since i went to 5A fuses from 3A i haven't blown any yet
12:03 AM rue_shop3: :)
12:03 AM rue_shop3: whats the amp rating?
12:04 AM Tom_L: the new splash guard i like though
12:04 AM Tom_L: no leaks
12:04 AM Tom_L: except when the tube misses the bucket
12:05 AM rue_shop3: how much meat did you leave on the bottom of the plate for that project (to hold it)
12:05 AM Tom_L: ?
12:05 AM Tom_L: oh the foil i leave to punch out?
12:05 AM Tom_L: maybe .001" programmed
12:05 AM rue_shop3: I set mine up with holding tabs, I'm supposed to overcut by 0.25mm, this one just left me with foil
12:06 AM Tom_L: still working on that a bit
12:06 AM rue_shop3: 3 thou
12:06 AM Tom_L: the plate may not be completely flat which affects setting the tool height
12:07 AM rue_shop3: try my zero a little lower...
12:07 AM rue_shop3: yea
12:07 AM Tom_L: i undercut the slot and it still didn't break out
12:07 AM rue_shop3: hence why I like the tabs
12:08 AM Tom_L: but i was cutting .002" below the bottom
12:08 AM Tom_L: so i need to figure that out a bit
12:08 AM Tom_L: the plate may not be completely flat eitehr
12:08 AM Tom_L: better head to bed here
12:09 AM Tom_L: you got your days and nights mixed up
12:12 AM rue_shop3: ooo goggles for this one
12:15 AM rue_shop3: tommroow is holiday
12:30 AM rue_shop3: dont want to jinx it, but at 100mm/min the bit isn't breaking...
05:39 AM Tom_L: nice
05:54 AM rue_: I settled on 85mm/min with a DOC of 0.2mm, any more than that, and it needs cooling and clearing
05:57 AM rue_bed: it was doing 100mm/min at 0.4mm, but needed constant attention
06:04 AM Tom_L: chip clearing?
06:04 AM Tom_L: or just lonely?
06:07 AM Tom_L: even though i scrapped a part it makes me feel good the machine went where it was told
06:08 AM Tom_L: i bet it won't happen again
04:17 PM Tom_L: finally got a good part off
04:23 PM rue_shop3: washing the chips away cause there is coolant and you can just blow them off with a little puff of air
04:23 PM rue_shop3: cool
04:23 PM Tom_L: uploading videos
04:23 PM Tom_L: stay tuned
04:26 PM ASRock_pc: when they're available:
04:26 PM ASRock_pc: https://www.youtube.com/watch?v=ZqDBxswIAFE&feature=youtu.be
04:28 PM ASRock_pc: https://www.youtube.com/watch?v=wEzwjr49o2U&feature=youtu.be
04:29 PM ASRock_pc: https://www.youtube.com/watch?v=k8FyszGAllo&feature=youtu.be
04:29 PM Tom_L: that should keep ya busy for a bit once they're uploaded
04:29 PM rue_shop3: damn youtube for changing the broser support again
04:30 PM Tom_L: the last one will be done first, it's the shortest
04:31 PM Tom_L: woops i forgot to rotate them
04:31 PM rue_shop3: pretty good considering it needs the retainer
04:31 PM Tom_L: they're private anyway
04:31 PM rue_shop3: I'm not wirried about someone trying to make them, its hard enough when yo uknow how to
04:31 PM Tom_L: that was the edit i did to fix the flange
04:31 PM Tom_L: i think it worked
04:31 PM rue_shop3: the problem is that, with the retainer, will the can turn easily
04:32 PM Tom_L: it's snug, i don't think so once A10 is on it
04:32 PM Tom_L: i just gave it relief around the edge a bit
04:32 PM Tom_L: i'll take a pic and show you
04:35 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/Extra/A9_can_grip.jpg
04:36 PM Tom_L: the ballnose looks better too
04:37 PM Tom_L: i hope i didn't bring the ballnose up too close to the L corner
04:39 PM Tom_L: i still didn't get the last profile cut quite deep enough
04:39 PM Tom_L: it should break out easier than it did
04:39 PM Tom_L: i can fine tune that
04:42 PM Tom_L: 2nd one is ready
04:45 PM Tom_L: i put the 2 cutting on my channe
04:45 PM Tom_L: l
05:08 PM rue_shop3: I had the impression with the new software is was more or less "here is your bit, make this"
05:09 PM rue_shop3: nice (videos)
05:11 PM rue_shop3: thats a lot of air!
05:12 PM rue_shop3: you should try a pulser
05:22 PM rue_shop3: that peice looks good
05:22 PM rue_shop3: hah, did you have it shamfer the rectangular hole too?
05:26 PM Tom_L: no it's a debur tool
05:26 PM Tom_L: https://www.mscdirect.com/browse/tnpla/82915570?cid=ppc-google-New+-+Abrasives+-+PLA_sqF1QRi19___164124448223_c_S&mkwid=sqF1QRi19|dc&pcrid=164124448223&rd=k&product_id=82915570&gclid=CjwKCAiAk4XUBRB5EiwAHBLUMayCRC_jz3nQ5FjQy03LYj3kkzCIEzpuQWB6NWZA1_peL7tfaEp8MxoCDw0QAvD_BwE
05:26 PM Tom_L: similar
05:33 PM rue_shop3: so then for the hell of it, want to make aluminum parts for a 3d printer?
05:33 PM rue_shop3: we should figure out how to try that peice too
05:34 PM rue_shop3: I need to go shopping, I need milk, but I just want to go to sleep
05:34 PM Tom_L: sure
05:34 PM rue_shop3: but this is interesting, I get tired at the same time nomatter when I wake up
05:34 PM Tom_L: gimme some dimensions
05:35 PM Tom_L: i'm gonna send you these parts
05:35 PM rue_shop3: ok, how about I PP you shipping feez?
05:35 PM Tom_L: for your printer?
05:35 PM rue_shop3: you should make one
05:35 PM Tom_L: no
05:35 PM Tom_L: i don't want one
05:35 PM Tom_L: i've got a mill :D
05:35 PM rue_shop3: oh cmon, everyone is doing it
05:35 PM rue_shop3: its addictive
05:36 PM Tom_L: not so much
05:36 PM rue_shop3: quick turnaround
05:36 PM Tom_L: remember that space thing?
05:36 PM rue_shop3: the gimbal?
05:36 PM Tom_L: mine is smaller than yours
05:36 PM Tom_L: no.... space
05:36 PM rue_shop3: oh THe timespace thing
05:37 PM Tom_L: no
05:37 PM Tom_L: the occupied vs unoccupied space
05:37 PM rue_shop3: yea, no 3d volume left
05:37 PM rue_shop3: but you can put the printer in the house :)
05:37 PM Tom_L: and mine has been .rar'd
05:37 PM rue_shop3: I'm gonna see if I can stick 6 printers in the house
05:37 PM rue_shop3: heh
05:37 PM Tom_L: you got nobody to tell you no either
05:38 PM rue_shop3: well, I made 9 aluminum triggers in the process of working out the speeds/feeds I can do on this sherline
05:38 PM Tom_L: i think i'm gonna get a nice vise for it eventually
05:38 PM Tom_L: can that 5/16 part be made from 1/4?
05:39 PM Tom_L: A12
05:39 PM Tom_L: you've got one part from 5/16
05:39 PM Tom_L: it's not too easy to find that thickness
05:39 PM rue_shop3: na, its got to be thick to get around A9
05:39 PM Tom_L: i found some 2024 but i think it sucks to machine
05:39 PM rue_shop3: funny, we have challanges here getting 1/4"
05:40 PM Tom_L: i can get 1/8 1/4 3/8 by the ton
05:40 PM rue_shop3: wonder what it would cost to send you a peice
05:40 PM Tom_L: not worth it
05:40 PM rue_shop3: 5/16" plywood....
05:40 PM rue_shop3: I mean, you cant play with feedrates, but you can work out the programming
05:41 PM rue_shop3: the trickey bit is the slot @ 90 degrees
05:41 PM Tom_L: which part?
05:41 PM Tom_L: i ran the ballmill at 120% which was 7ipm
05:42 PM Tom_L: i'm gonna change it in the cad file
05:42 PM rue_shop3: A12
05:42 PM Tom_L: what's hard about that?
05:43 PM rue_shop3: positioning it
05:43 PM rue_shop3: we have a 3d printed jig, thats sits in the cnc vise
05:43 PM Tom_L: i need an inch version of that one from you
05:43 PM rue_shop3: k
05:43 PM Tom_L: the one i have is about 4' across
05:43 PM rue_shop3: does svg work any better for you?
05:43 PM Tom_L: just send like you have been
05:43 PM Tom_L: it works
05:44 PM rue_shop3: these arbitrarily shaped peices are a challange
05:44 PM rue_shop3: I dont have good data on the slot
05:45 PM rue_shop3: we use one of the cnc to cut about 10cm into it, then hand file it a bit longer in one spot
05:45 PM Tom_L: it would be good to have dimensioned drawings
05:45 PM rue_shop3: well, how about I make a drawing on a scaled grid?
05:46 PM Tom_L: i'll draw them up and send a pdf
05:46 PM rue_shop3: would it be easier to generate than the dxf?
05:46 PM Tom_L: once you get me good data
05:46 PM Tom_L: no
05:46 PM Tom_L: dxf is fine
05:46 PM rue_shop3: k
05:46 PM Tom_L: as long as it's inch
05:48 PM rue_shop3: I will leave a line across it in the path best approximating the cut
05:51 PM rue_shop3: ----> large hole is #43 small hole is 1/16"
05:52 PM rue_shop3: ok there are two obvious strikes thru it, they are the profile of the cut, the take-out angle of it isn't that important
05:53 PM rue_shop3: ----> its 1.373" long
05:53 PM rue_shop3: can you view it and edit out lines?
05:54 PM rue_shop3: http://ruemohr.org/%7Eircjunk/not_public_dont_open/tom/A12.dxf
05:55 PM rue_shop3: your now in imperial.
05:57 PM Tom_L: booting to 64bit..
05:58 PM Tom_L: those are 5/16 thick?
05:58 PM Tom_L: that has a slot in the edge?
05:59 PM rue_shop3: yes, they have a 1/8+" slice in them that makes them fit over A9
05:59 PM rue_shop3: those two out-of-place lines are the profile of the slot
05:59 PM Tom_L: fit over a9 where?
05:59 PM rue_shop3: shall I take pics?
05:59 PM Tom_L: you probably have pics
05:59 PM rue_shop3: http://www.ruemohr.org/p1080919.jpg
06:00 PM Tom_L: oh i see now
06:00 PM rue_shop3: http://www.ruemohr.org/ did I show you the awefull placeholder webpage we made?
06:01 PM rue_shop3: takes about 4 hours of labour to make them
06:02 PM rue_shop3: I spent lots of yesterday just making a head, and I blew it
06:02 PM Tom_L: we'll cut that down by about 3.25
06:02 PM rue_shop3: I have some aluminum solder I'll see if I can fix it
06:02 PM Tom_L: so the slot can't be a straight cut?
06:02 PM Tom_L: it has to taper up?
06:02 PM rue_shop3: we do it as a stright cut, then hand file that extra bit out of it
06:03 PM rue_shop3: paint in the ass
06:03 PM rue_shop3: ...
06:03 PM Tom_L: but does it need to be like that?
06:03 PM rue_shop3: we have 2 books on how these are made
06:03 PM rue_shop3: yea, otherwise it dosn't swing open enough
06:03 PM rue_shop3: evil part isn't it?
06:03 PM rue_shop3: see that spring?
06:04 PM rue_shop3: hand made too
06:04 PM Tom_L: lemme come up with something and i'll send you a pdf
06:04 PM Tom_L: i know
06:04 PM Tom_L: could that slot be ball milled?
06:04 PM rue_shop3: I dont see why not
06:04 PM rue_shop3: like I say, the angle of that take-out it does on the left isn't important
06:04 PM Tom_L: i can do that probably fairly easy
06:05 PM Tom_L: i just packaged up all my A10 A9 parts though
06:05 PM Tom_L: scrap or not
06:05 PM Tom_L: you're gettin em
06:05 PM rue_shop3: :) no hurry
06:05 PM rue_shop3: thankyou
06:05 PM rue_shop3: ok I'm gonna burn lunch and miss the store
06:05 PM rue_shop3: damn I cant go to the store in these clothes
06:05 PM Tom_L: i gotta load some fuxxing lightroom thing for her then i'll get back on it
06:06 PM rue_shop3: np
06:06 PM Tom_L: the dxf has no slot though right?
06:06 PM rue_shop3: its been an interesting project, me and a fellow worked out how to make these, and my buddy has been almost completely shewing away on it on his own
06:06 PM rue_shop3: I just keep the machines working :)
06:07 PM Tom_L: i think it came in good this time
06:07 PM rue_shop3: there are two lines in the dxf representing the slot
06:07 PM Tom_L: is your lines accurate where you want the slot?
06:07 PM rue_shop3: I made them obviously not part of the part
06:07 PM Tom_L: i can use that and make a 3d part from it
06:07 PM rue_shop3: sure
06:07 PM Tom_L: gimme 15 min and i'll have it
06:07 PM rue_shop3: not sure how to print it, but I can work that out
06:07 PM rue_shop3: np I have to go shooping
06:08 PM rue_shop3: and change, and eat lunch
06:08 PM rue_shop3: its 4pm
06:08 PM rue_shop3: ...
06:09 PM Tom_L: those are all radiuses
06:09 PM Tom_L: i can just redraw that in smartcam instead of making poly lines
06:09 PM Tom_L: i'll go ahead and make a solid part in catia though
06:10 PM Tom_L: because i can pull the dimensions from it there easy
06:37 PM rue_: its a simple part, its just evil
07:05 PM Tom_L: q
07:05 PM Tom_L: can the lines off the large arc be parallel to each other?
07:05 PM Tom_L: gonna shower while i wait for an answer...
07:06 PM Tom_L: i printed a dwg and am gonna dimension it and just draw it in smartcam
07:06 PM Tom_L: will be faster to machine
07:07 PM Tom_L: but i'll make the solid in catia also
07:07 PM Tom_L: i will hold the profile in a vise and slice it like butter
07:24 PM Tom_L: rue_shop3, i need to verify a couple dimensions
07:33 PM Tom_L: can't wait... gotta keep progress rollin: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/Extra/A12.jpg
07:34 PM Tom_L: so that slot can be done a couple ways easy
07:35 PM Tom_L: hold one of the edges perp to the cutter
07:35 PM Tom_L: and ballnose the other one up hill
07:35 PM Tom_L: after you cut the length
07:37 PM rue_: oh sorry, 1 min
07:37 PM Tom_L: is that slot supposed to intersect the hole?
07:37 PM rue_: yes
07:37 PM rue_: in reality it cuts half way thru the hole
07:37 PM Tom_L: it won't quite be with a ballnose
07:37 PM rue_: so we drill it before slotting
07:37 PM rue_: its not a requirement, it just does
07:38 PM Tom_L: but i could lay that part flat on the vise vertical and slot it with an endmill then climb uphill to get the other side
07:38 PM Tom_L: generally you wanna use a ballnose to do that
07:38 PM rue_: well
07:39 PM Tom_L: can the 2 lines off the large radius be parallel to each other?
07:39 PM rue_: maybe the other option is a horis slotting tool of some kind
07:39 PM rue_: hah, sorry, you have the slow backwards
07:39 PM rue_: the non-slot should ebt eh slot and vise versa
07:39 PM Tom_L: huh?
07:39 PM rue_: it goes thru the majority of the material
07:39 PM Tom_L: ahh
07:39 PM rue_: srry
07:40 PM Tom_L: one sec
07:40 PM rue_: I'm fighting to stay awake again
07:40 PM rue_: this is frustrating
07:40 PM rue_: wait, I was having problems hours ago too
07:40 PM rue_: ugh
07:40 PM rue_: I'm trying to work out what you mean by parallel
07:41 PM rue_: 'can the lines off the large arc be parallel to each other?'
07:41 PM rue_: for the slot, yes
07:41 PM Tom_L: for the perimeter
07:42 PM rue_: that general bit of profile needs to stay the same
07:42 PM rue_: it fits in when its latched, which I cant see a picture of
07:43 PM Tom_L: it's just a few degrees different
07:43 PM Tom_L: and the lines are quite short
07:43 PM rue_: ok, your prolly ok then
07:47 PM Tom_L: now look at the pic
07:47 PM rue_: http://ruemohr.org/~ircjunk/not_public_dont_open/tom/p1080748.jpg
07:47 PM Tom_L: that what you're goin for?
07:47 PM rue_: you can kinda see how it fits in
07:47 PM rue_: there ya go
07:48 PM Tom_L: i know how it works
07:48 PM Tom_L: it's a cam
07:48 PM rue_: yep, overcentre
07:48 PM Tom_L: closed past center
07:48 PM rue_: when we first designed it we missed, cause we inadvertently bumped the positions of the ends by 1mm and it wouldn't overcentre
07:49 PM rue_: its kinda close now, we have thought of adjusting it a bit, too much at once will just result in a pile of rubble tho
07:49 PM Tom_L: ok so you make a jig
07:49 PM Tom_L: with 4 pin holes
07:49 PM rue_: I do, want to see an stl of the jig?
07:49 PM rue_: oh, you , k...
07:50 PM Tom_L: the first set fit the large and small holes with the short of the slot horizontal
07:50 PM Tom_L: you cut straight across it with a flat cutter
07:50 PM rue_: I run a wobbly 1/8" bit thru it
07:50 PM Tom_L: you then reposition it with the other side horizontal with the pins
07:50 PM rue_: ah
07:50 PM Tom_L: just don't forget to pull the pins once you clamp it in place
07:50 PM Tom_L: ez peezy
07:51 PM Tom_L: you can do that
07:51 PM rue_: wait, that worked but then I realized it would cut thru the pins
07:51 PM Tom_L: i would probably do that or ball mill it
07:51 PM Tom_L: you pull the pins on the fixture after you clamp it
07:51 PM rue_: ok I see
07:51 PM Tom_L: and the fixture is a half of a vise jaw held in place
07:52 PM Tom_L: the other way to do it is mill softjaws the shape of those 2 positions
07:52 PM Tom_L: no pins
07:52 PM Tom_L: we would likely do it that way
07:52 PM rue_: can you view an stl?
07:52 PM Tom_L: and mill 2 at once
07:52 PM Tom_L: one horizontal and the other vertical in the same jaw set
07:52 PM Tom_L: i can
07:55 PM Tom_L: i would likely mill a set of softjaws to fit the part for those slots and have 2 positions but cut them both at once on 2 parts
07:55 PM rue_: I cant
07:55 PM rue_: ...
07:55 PM Tom_L: just sayin
07:55 PM rue_: technical difficulties, please stand by..
07:55 PM Tom_L: do you have a vise?
07:56 PM rue_: yea, hold on, problems backing up on me
07:57 PM rue_: !@#%$@$#^@$^
07:57 PM Tom_L: printer fark up?
07:58 PM rue_shop3: #Q$%@$^ FFFFFFFFFFFFFF printer screwed up a big job
07:58 PM rue_shop3: and my main computer dosn't have a working stl viewer
07:59 PM rue_shop3: STAND BY
08:01 PM rue_shop3: and now I cant find what I'm looking for
08:02 PM rue_shop3: clasp -> holderjig
08:02 PM rue_shop3: STAND BY
08:04 PM rue_shop3: http://ruemohr.org/%7Eircjunk/not_public_dont_open/tom/holderjig-r1-s.stl
08:04 PM rue_shop3: check out that guy
08:04 PM rue_shop3: and I'll work down the technology problem backlog
08:06 PM rue_: in ONE of these browser tabs I have a link to source code for a stl viewer that I need to tweek some day
08:07 PM rue_: that stl, is the jig that we use for the slot
08:07 PM rue_: its a bit narrower than the latch
08:07 PM Tom_L: it sorta came in
08:07 PM Tom_L: i see the profile
08:08 PM rue_: its tacked to the vise jaw
08:08 PM Tom_L: i would do that and one more for the other half
08:08 PM rue_: you nestle the latch into it, and tighten the vise
08:08 PM Tom_L: that's what we do with softjaws all the time
08:08 PM rue_: so your idea is just a step above what I have there
08:08 PM Tom_L: keep the jaws with the part setup
08:08 PM Tom_L: the pins was just an easy alternate for your
08:09 PM Tom_L: setup
08:09 PM Tom_L: i'd do the jaws personally
08:09 PM Tom_L: i need to get my 4" VISE
08:09 PM rue_: its easy to print stuff like that
08:09 PM Tom_L: and turn off capslock
08:10 PM Tom_L: but you can't print and use that as a holder accurately
08:10 PM Tom_L: it would be close
08:10 PM rue_: the printer will hit within 0.5mm without trying
08:11 PM rue_: if I tweek for bugs they wont admit to, I can get prolly within 0.1
08:11 PM rue_: ok
08:12 PM rue_: my weekend is spiraling around the drain
08:12 PM rue_: the head on the printer got bumped and it skipped steps, I'm trying to print a large experimental peice for the new printer
08:12 PM rue_: so I just lost a lot of plastic
08:12 PM Tom_L: i think i need to scale this in smartcam
08:13 PM rue_: and the other printer had the filament snag, and missed any meat on a few layers of another part
08:13 PM Tom_L: yeah
08:13 PM Tom_L: it came in smartcam big
08:13 PM rue_: I need to make another spool holder with a few more cm on it
08:13 PM rue_: its metric
08:13 PM Tom_L: i thought you converted it
08:14 PM rue_: scale by 0.0393701
08:14 PM rue_: the stl ^^
08:14 PM rue_: the dxf if imperial
08:15 PM Tom_L: it's about 1.3 end to end?
08:17 PM rue_: <rue_shop3> ----> large hole is #43 small hole is 1/16"
08:17 PM rue_: <rue_shop3> ok there are two obvious strikes thru it, they are the profile of the cut, the take-out angle of it isn't that important
08:17 PM rue_: <rue_shop3> ----> its 1.373" long
08:18 PM rue_: :) I put markers on the lines so I could find them
08:18 PM Tom_L: pretty close
08:19 PM rue_: :)
08:20 PM rue_: I need all my stuff to pay for itself so I dont have to work till I'm 102
08:20 PM rue_: how the hell am I gonna build a new hours?
08:20 PM Tom_L: i'm trying to put the mill to work
08:20 PM rue_: house
08:20 PM rue_: you know of anyone more promising than me to get rojects from?
08:21 PM rue_: :)
08:21 PM Tom_L: at least i didn't have to fight this one to get a good profile
08:21 PM rue_: we didn't even set up for taxes, under $10000/yr and nobody cares (officially)
08:21 PM Tom_L: i'm just using the poly lines
08:22 PM rue_: yea, less the slot, its an easy part
08:22 PM Tom_L: i got 35/hr programming this crap 25yrs ago
08:22 PM rue_: nice.
08:22 PM Tom_L: it paid for smartcam in a year
08:22 PM Tom_L: :)
08:22 PM Tom_L: ~6k bak then
08:22 PM rue_: were targeting $20/hr for making them, were not quite there
08:26 PM rue_: playing with the feed rates this weekend will have helped a lot
08:26 PM rue_: 85mm/min is AWESOME
08:26 PM Tom_L: i'll try to send those tomorrow
08:26 PM Tom_L: i'll have to mill another one for me
08:26 PM rue_: if I could do a coolant system, I could go from a DOC of 0.2 to 0.4
08:27 PM Tom_L: you can
08:27 PM Tom_L: it's $35 a gallon condensed
08:27 PM Tom_L: 4 oz per gallon
08:27 PM rue_: your in manufacturing central up thre, are the jobs you were doing for big shops or shorter runs?
08:27 PM Tom_L: i dunno, is cessna, boeing big?
08:28 PM Tom_L: most of his work was for cessna
08:28 PM Tom_L: i just did it to help my bud out
08:29 PM rue_: cool
08:32 PM Tom_L: ran some machines while i was there
08:32 PM Tom_L: cnc lathe and mills
08:33 PM Tom_L: back in the 70's ? i ran multi spindle lathes
08:33 PM Tom_L: manual
08:33 PM Tom_L: well, cam driven
08:33 PM Tom_L: 30hp main motor
08:36 PM rue_: :)
08:36 PM rue_: cessna must have some large machines
08:37 PM rue_: I presume for dealing with making panels?
08:37 PM Tom_L: they merged with beechcraft under the textron name now
08:37 PM Tom_L: they had at least 2 plants before the merge
08:38 PM Tom_L: i've never been in their machine shops but i know they've got some huge equipment
08:39 PM Tom_L: spirit (old boeing) covers a good mile or more
08:39 PM Tom_L: i'd guess
08:43 PM Tom_L: if i had material i'd run one of these
08:46 PM Tom_L: haha
08:46 PM Tom_L: i did this part already once
08:47 PM Tom_L: i dunno where i put it though
08:47 PM Tom_L: but i've got a gcode file for it so i had to have made it
09:06 PM rue_shop3: :/ oops!
09:06 PM Tom_L: it's done, i'm working on the slot
09:09 PM rue_shop3: was talking to one of the old robotics kids today, pointed out that I should make non-printed parts for the 3d printers while I'm waiting for the printed parts
09:26 PM Tom_L: sh**
09:26 PM Tom_L: i can't remember how to rotate the tool in my model
09:27 PM rue_shop3: this is why we use it, (or lose it)
09:27 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/toolplane1.jpg
09:27 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/toolplane2.jpg
09:27 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/toolplane3.jpg
09:27 PM Tom_L: like that
09:28 PM Tom_L: i can cheat i suppose
09:33 PM Tom_L: hah
09:43 PM Tom_L: ok i got one for ya
09:47 PM ASRock_pc: https://www.youtube.com/watch?v=nkYcvd9EKTo&feature=youtu.be
09:47 PM Tom_L: just like that
09:51 PM Tom_L: only i need to flip the right one over :(
10:03 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/Extra/A12_P2_visejaws.jpg
10:03 PM Tom_L: i oriented the parts so the same side would be against the back vise jaw for both cuts in case it was off center a tiny bit
10:04 PM Tom_L: the video shows them both oriented different
10:05 PM Tom_L: so you indicate off the back jaw and move the cutter forward .0625"
10:06 PM Tom_L: err, .3125 i think
10:06 PM Tom_L: no, .15625"
10:07 PM Tom_L: half the 5/16" thickness less the pocket depth
10:14 PM rue_shop3: hahaha 2 at once
10:14 PM rue_shop3: but hte right one is upside down
10:14 PM rue_shop3: ok yea
10:15 PM Tom_L: i fixed it
10:15 PM Tom_L: in the jpg
10:15 PM rue_shop3: :)
10:15 PM rue_shop3: I see
10:15 PM Tom_L: one swipe gets both done
10:15 PM Tom_L: just run 2 parts at once
10:15 PM rue_shop3: that type of programming must be different, you aren't really going off drawn geometry
10:16 PM Tom_L: see you set that up on a G55 offset and you can run P1 and P2 at the same time
10:16 PM rue_shop3: Tom_L, the other trick is that it needs to be a hair over 1/8"
10:16 PM Tom_L: so you're profiling the part then running it in the vise all at once if you want
10:16 PM rue_shop3: so it clears A9
10:16 PM rue_shop3: yea, I like the 2 at once thing
10:16 PM Tom_L: ok, i can offset the cutters
10:17 PM rue_shop3: can you also control the length of the 3rd stroke in that image?
10:17 PM Tom_L: i can move anything i want
10:17 PM rue_shop3: well, that is to say, trim down the extra stroke past the right part
10:17 PM Tom_L: i can sorted the 3rd and 4th ones
10:17 PM Tom_L: the 4th one doesn't hit the whole part either
10:17 PM rue_shop3: I use my old machine for that, and most of the time is spent cutting air
10:18 PM Tom_L: i can optimize the cuts once they're where they are supposed to be
10:18 PM rue_shop3: k
10:18 PM Tom_L: i'll show you another pic in a few min
10:18 PM rue_shop3: which program did that last image?
10:18 PM Tom_L: ?
10:18 PM Tom_L: that's smartcam
10:18 PM rue_shop3: ok
10:18 PM Tom_L: with some windows capture tool
10:19 PM rue_shop3: yea
10:28 PM Tom_L: refresh that pic
10:28 PM Tom_L: i left the cutter on one so you can see it clears
10:29 PM Tom_L: i should trim 4 more
10:39 PM rue_: there go
10:40 PM rue_: is the red the vise?
10:40 PM rue_: to make the slot a bit thicker than 1/8" would you make offset paths or use a larger bit?
10:55 PM Tom_L: red is vise
10:56 PM Tom_L: could make 2 passes offset
10:59 PM rue_: that or I try to find a 3.5mm? cutter
10:59 PM Tom_L: 2 passes would be more likely to find
11:00 PM Tom_L: oops, trash night... better get that out
11:00 PM rue_: hah, you dont have bears
11:00 PM rue_: I cant even put mine in the can till the morning of
11:01 PM rue_: so much as 1 popicle wrapper and BAM their on it. popsicle wrapper all over the lawn
