[05:18:00] <XXCoder> hey
[05:18:22] <XXCoder> jthornton: damn machine got clogged and spilled a LOT of coolant 10 minutes from end of shift
[05:18:43] <XXCoder> mopped a lot in a hurry but still incomplete by time i left
[05:18:49] <jthornton> made a big mess
[05:19:15] <XXCoder> machine is still clogged, no choice but just leave it.
[05:19:21] <XXCoder> i hate leaving job like that :(
[05:21:35] <jthornton> you have central coolant tank for whole shop?
[05:23:21] <XXCoder> nah its from one mill
[05:23:28] <XXCoder> its big one so tons gallons
[05:23:39] <XXCoder> hell the sill probably just dented it a little
[05:31:10] <XXCoder> ya know
[05:31:22] <XXCoder> centeral coolant would be pretty scary lol
[05:31:28] <XXCoder> something breaks in middle of night and...
[05:38:21] <jthornton> my vmc came from someplace that central coolant but the seller built me a tank for it
[05:39:57] <jthornton> dang I have 0.5GB of data to burn today lol

[09:57:47] <skunkworks> pcw_home: is there a single smart serial port device? I don't want to waste a 7i76 for just one smart serial port..
[09:58:32] <skunkworks> or would it as 'simple' as using a line driver?
[09:59:51] -!- holzjunkie has joined #linuxcnc
[10:01:25] <Jymmm> what is a "smart" serial port?
[10:01:54] -!- HSD has joined #linuxcnc
[10:02:03] <skunkworks> pcw_home: you sell 485x1 One channel RS-485/RS-422 adapter
[10:02:42] <skunkworks> Jymmm: mesa cards use them as an expansion option... It is their standard I think
[10:02:50] <Jymmm> ah
[10:03:11] <skunkworks> uses network cable to inter-connect certain cards.

[10:50:02] <pcw_home> No there's no single channel device other than the RS-485 adapter, I may have a 7I74 in my junk drawer though
[10:52:22] <JT-Shop> I thought you cleaned out your junk drawer when you moved LOL
[10:55:14] <skunkworks> pcw_home: I don't need that many smart serials.. do you have one of the RS-485 converters in stock?
[10:56:15] <pcw_home> Its re-grown...
[10:56:49] <pcw_home> Yeah they should be in stock
[10:58:31] <skunkworks> ok - let me think of things I need and make an order :)
[10:58:35] <JT-Shop> I know how that goes lol
[10:58:50] <rene_dev_> this would probably work: https://www.ebay.de
[10:59:50] <skunkworks> rene_dev_: cool - except this gives me a reason to buy more mesa stuff... ;)

[12:11:00] * Loetmichel is a little bit frustrated. We got 8 alu enclosures for mini PCs from china where the mainboard bolt pattern was 180° rotated. So i instructed the coworker: take a measurement from the left lower corner, apply to the upper right corner, drill and set a bolt, same for the other four bolts. Now we just wanted to close the lid on the PCs: not one fits. Up to 25mm deviation between
[12:11:01] * Loetmichel CPU cooler and air duct in the lid. Coworker: "i didnt knew that the position is critical, so i just threw the board in and marked the holes."... MAAAN, to work with PROs for ONCE, please... :-(
[12:11:27] -!- P1ersson has quit [Ping timeout: 240 seconds]
[12:13:45] <jthornton> you have all the fun lol
[12:14:34] <SpeedEvil> To be fair, 25mm is a fair level of skill to manage to mismark stuff by. That takes expertise.
[12:14:50] <Loetmichel> wouldnt call that fun... means that i will have to work the weekend again. deadline is monday morning at the customer for those 8 boxes...
[12:15:50] <Loetmichel> SpeedEvil: http://www.cyrom.org
[12:16:02] <gloops> 25mm is a funny amount to mis-measure, im usually 100mm out
[12:16:13] <Loetmichel> thats the box and the mainboard... can you imagine to misplace the board by 25mm there?
[12:16:48] <SpeedEvil> If I had marked it by trying to mark it in yellow, in the snow, sure.
[12:18:05] <fragalot> Loetmichel: just print a duct, it will be fine! :D
[12:18:20] <fragalot> SpeedEvil: you wouldn't make it 25mm with that
[12:18:35] <Loetmichel> fragalot: not possible
[12:18:47] <Loetmichel> the aluminium would sit on the fan
[12:18:53] <fragalot> Loetmichel: now now i went to this seminar, and everything can be solved by 3D printing
[12:19:52] <Loetmichel> look at the picture. the duct sits on an aluminium "channel". you cant move the hole in the alu
[12:20:03] <Loetmichel> especially not past the mounting screws
[12:20:41] <fragalot> that's because you didn't follow a course on designing for 3D printing
[12:20:43] <Loetmichel> aside from that: 8 new ducts would be two days printing
[12:20:54] <Loetmichel> meaning moving the board is probably faster ;9
[12:20:58] <fragalot> :D
[12:21:03] <fragalot> printing is not hands-on though
[12:21:06] <SpeedEvil> Loetmichel: origami
[12:22:32] <Loetmichel> hmm?
[12:22:35] <Loetmichel> what do you mean
[12:22:41] <Loetmichel> it IS already origami ;)
[12:23:01] <fragalot> :)
[12:23:05] <SpeedEvil> Origami ductwork
[12:23:55] <Loetmichel> ah. doesen work. as i said: the cpu fan protudes into the aluminium channel
[12:24:17] <Loetmichel> so whatever i do with the printed duct: wouldnt help
[12:26:05] <fragalot> increase hole size
[12:26:09] <fragalot> put duct over to cover up the mess
[12:26:10] <fragalot> done
[12:26:26] <fragalot> get the fancy aluminium filled plastic to print the ducts for EMI.
[12:28:28] <SpeedEvil> Do up the screws slowly with the fan on, so the blades conform
[12:29:10] <Loetmichel> hihi
[12:29:32] <Loetmichel> THAT'll work with the (military) customer for sure, SpeedEvil
[12:29:34] <fragalot> SpeedEvil++
[12:29:35] <Loetmichel> :)
[12:29:53] <SpeedEvil> Loetmichel: Write up a proper seventeen point procedure for it.
[12:30:00] <fragalot> Loetmichel: army or navy?
[12:30:05] <Loetmichel> no idea

[14:09:26] <PL7icnc> pcw_home, are You Sir Online
[14:11:08] <CaptHindsight> PL7icnc: if you stay in the channel for more than 10 minutes you might get a reply
[14:12:11] <PL7icnc> Thanks but not Today Posible

[14:13:55] <Loetmichel> *sigh*
[14:14:01] <Loetmichel> why does he try at all?
[14:14:43] <CaptHindsight> if he reads the logs he might find email or the forums more appropriate
[14:18:37] <CaptHindsight> Loetmichel: how did you end up with such a talented coworker?
[14:20:39] <Loetmichel> CaptHindsight: old worker rehired by the boss a few months ago
[14:21:35] <Loetmichel> and i get more and more to the conclusion that there was a reason he got fired a few years ago (before my time at that company)
[14:22:48] <FinboySlick> Loetmichel: Makes one wonder if it would end up cheaper to have an on-site laser cutter and break to make enclosures.
[14:23:21] <Loetmichel> FinboySlick: i have an on-site CNC mill
[14:23:35] <FinboySlick> Then again, I guess the problem wasn't the manufacturing but the ordering.
[14:23:43] <Loetmichel> and the programs ready (from the prototype) to make 8 new bottoms
[14:24:05] <Loetmichel> problem is the time i takes to cover them with powder coating again
[14:24:25] <Loetmichel> we dont have a powder coating oven at the company
[14:27:43] <CaptHindsight> Loetmichel: you keep making your boss look good, hope he's compensating you for it
[14:28:32] <Loetmichel> CaptHindsight: [13:13] <Loetmichel> maan. just got the monthly salary slip... that paper must be made of onions... salary: 3050.- eur. transferred to my bank account: 1643.97 eur... rest is taxes and (health/old age nursing/retirement) insurances. ;)
[14:28:39] <Loetmichel> qustions?
[14:40:24] <fragalot> does that number include overtime?

[14:51:22] <Loetmichel> Tom_L: indeed ;)
[14:51:41] <Loetmichel> fragalot: i dont get paid for overtime
[14:51:48] <Loetmichel> i chose to get offdays for it
[14:52:13] <Loetmichel> ... of which i have 26 from last year and another 8 from this year so far.
[14:52:27] <fragalot> i'm no longer allowed to carry mine over :(
[14:52:41] <Loetmichel> i cant take them
[14:52:46] <fragalot> lol
[14:53:09] <Loetmichel> i would LIKE to stay a few weeks at home by now. pretty burned out at the moment
[14:53:16] <fragalot> my dad's just retired on his saved up holiday
[14:53:34] <Loetmichel> no chance becaus every second day there is some other blunder i have to fix
[14:53:36] <fragalot> took several years off in a row
[14:54:04] <CaptHindsight> Blunderfixer
[14:55:04] <fragalot> have you ever looked into a cnc plate punch for your enclosures?
[14:55:28] <fragalot> it'd spit the panels out in minutes, giving you a lot more time to fix said blunders

[14:56:47] <Loetmichel> fragalot: not useful for 8 box series
[14:57:02] <Loetmichel> the punch would be more expensive than a whole 100 series made in china
[14:57:11] <fragalot> that's where you're wrong
[14:57:13] <gloops> this identify lark is getting boring
[14:57:20] <fragalot> our subcontractor does one-offs on his
[14:57:34] <Loetmichel> ah. sorry misunderstood
[14:57:38] <fragalot> just put the panel on (in our case a Rittal door panel & backplate), sketch out the holes & hit go
[14:57:45] <Loetmichel> you mean a cnc punching machine
[14:57:50] <fragalot> yes
[14:57:55] <Loetmichel> yes, we have a contractor at hand that does that
[14:58:17] <Loetmichel> i thought you meant a punch die that puts out whole boxes
[14:58:22] <Loetmichel> in one "BAMPF"
[14:58:22] <fragalot> no :)
[14:58:24] <Loetmichel> ;)
[14:58:27] <CaptHindsight> fragalot: https://www.youtube.com how will this help him?
[14:58:34] <Loetmichel> those tools are pretty expensive ;)
[14:58:43] <fragalot> lol
[15:00:21] <Jymmm> CaptHindsight: docks?
[15:00:37] <FinboySlick> I think fragalot meant one of those: https://www.youtube.com
[15:00:55] <fragalot> yup
[15:01:06] <fragalot> they aren't THAT expensive 2nd hand
[15:01:08] <Tom_L> CaptHindsight you gettin any snow up there?
[15:01:37] <FinboySlick> Tom_L: We are.
[15:01:39] <FinboySlick> Actually...
[15:01:46] <Loetmichel> CaptHindsight: our contractor has one of these (just without the robot feeders) https://www.youtube.com
[15:02:15] <FinboySlick> https://twitter.com
[15:02:20] <CaptHindsight> Tom_L: flurries
[15:02:22] <FinboySlick> Official government map.
[15:02:46] <FinboySlick> (closed roads due to storm)
[15:02:48] <Tom_L> supposed to get 5" on the weekend
[15:02:48] <CaptHindsight> fragalot: how does that help if the box is already bent?
[15:03:18] <fragalot> CaptHindsight: still punches holes into boxes if they're not too deep & the lid can be removed
[15:03:27] <CaptHindsight> he needs a CNC phasor for cutting out openings
[15:03:34] <Loetmichel> CaptHindsight: the box can be made anew
[15:03:39] <Loetmichel> its not that big of a problem
[15:03:49] <Loetmichel> if you have a CNC punch and the material
[15:03:54] <Loetmichel> files are there
[15:04:05] <Loetmichel> but we have no time to redo the powder coating
[15:04:19] <CaptHindsight> more messy area
[15:04:44] <CaptHindsight> powder coat spray booth and oven in one
[15:04:56] <fragalot> one of those inflatable spray booths? :P
[15:05:02] <CaptHindsight> oh oh , laser sintered powder coating!
[15:05:12] <fragalot> & just put the part on the dashboard of your car & park it in the sun to bake it
[15:05:26] <Loetmichel> CaptHindsight: i already suggested quite a few times to get a powder coating booth
[15:05:26] <CaptHindsight> have to wait until june
[15:05:30] <Loetmichel> and a small oven
[15:05:45] <Loetmichel> luckily boss has refused so far ;)
[15:05:52] <fragalot> cheap bastard :D
[15:06:08] <CaptHindsight> powdercoat applicator on laser sinter all in one!
[15:06:21] <CaptHindsight> on/and
[15:06:24] <Loetmichel> fragalot: it would be another thing only me can use though
[15:06:30] <Loetmichel> so its probably for the better ;)
[15:07:02] <CaptHindsight> Loetmichel: would you coworkers warm their lunches in the oven?
[15:07:10] <Loetmichel> nope.
[15:07:15] <fragalot> xD
[15:07:34] <Loetmichel> but the ONLY one i would trust with producing anything sellable in that booth is my apprentice
[15:08:03] <Loetmichel> which happens to have aborted an apprenticeship as a painter beforehand
[15:08:09] <Loetmichel> ... and myself
[15:08:47] <Loetmichel> all the other ones: dont give them a rattlecan and some parts to paint: it WILL end with a bunch of runners and "orange skin"...
[15:08:53] <Loetmichel> been there tried that
[15:09:06] <Loetmichel> i doubt they will be able to do better with a powder applicator
[15:09:32] <CaptHindsight> can imagine your entire workspace covered in pink powder
[15:09:38] <fragalot> harder to get those artifacts with powder coating I thought?
[15:09:54] <Loetmichel> THEY will get them. Trust me in that.
[15:10:03] <fragalot> what if I don't?
[15:10:24] <Loetmichel> CaptHindsight: i can
[15:10:27] <CaptHindsight> fragalot: I need an inflatable oven
[15:10:45] <Loetmichel> fragalot: your loss ;)
[15:10:50] <fragalot> CaptHindsight: let me know when you find one that can be used to heat treat stuff
[15:11:32] <fragalot> should fold up to the size of a shoe box, and be able to fit parts the same size as a shoebox when inflated
[15:11:51] <fragalot> half a shoebox would be fine too
[15:12:39] <Loetmichel> fragalot: sounds doable if it can be "flip up" instead of "inflateable"
[15:12:54] <fragalot> that'd be good too
[15:13:15] <Loetmichel> hrrrmp, if i only had time for all the things i could build ;)
[15:13:39] <fragalot> my list of things i've started keeps growing faster than the list of things i've finished
[15:14:00] <Loetmichel> same here ;)
[15:14:20] <CaptHindsight> fragalot: https://youtu.be
[15:14:49] <fragalot> difficult to control temperature of the overall part
[15:15:08] <CaptHindsight> why he's waving it around
[15:15:28] <fragalot> yea, no. :)
[15:15:43] <Loetmichel> CaptHindsight: steel is a funny thing
[15:16:12] <Loetmichel> you can make it red hot at one and and still hold it with your naked fingers half a foot from that
[15:16:38] <CaptHindsight> levitate and heat treat at the same time https://youtu.be

[15:18:18] -!- andypugh has joined #linuxcnc
[15:19:06] <miss0r> bah. I think I've bitten over more than I can chew here..
[15:19:21] <miss0r> I've bought home a siemens servo controller, that is making errors.
[15:19:52] <CaptHindsight> hardware or software problem?
[15:19:53] <miss0r> but you can get it to make the same error and fault out if you tap it lightly on the side with a screwdriver - which by the power of reasoning should mean a loose something.
[15:20:11] <miss0r> but I've been over it again and again. I can't find a single issue
[15:20:14] <miss0r> hardware
[15:20:27] <fragalot> they often have issues with broken pads
[15:20:31] <fragalot> difficult to find visually
[15:20:46] <CaptHindsight> rework every solder joint
[15:20:51] <fragalot> ^
[15:20:52] <Loetmichel> miss0r: get your glasses. resolder the control boards completely
[15:20:52] <miss0r> Indeed - also hard to find with a multimeter
[15:20:54] <CaptHindsight> we used to do that all the time
[15:21:01] <Loetmichel> and thourly
[15:21:04] <miss0r> Loetmichel: yeah, that won't take forever :)
[15:21:06] <Loetmichel> try again ;)
[15:21:15] <CaptHindsight> rework each pad and swap each electrolytic cap
[15:21:24] <miss0r> CaptHindsight: The caps check out
[15:21:33] <miss0r> frozen, heated, shaken ect.
[15:21:34] <fragalot> miss0r: CaptHindsight's suggestion is actually one that works a LOT of the time
[15:21:45] <miss0r> indeed
[15:21:48] <miss0r> I think I will do that
[15:21:48] <fragalot> joints that look good, might not be
[15:21:55] <fragalot> flux is your friend
[15:22:04] <Loetmichel> indeed
[15:22:20] <miss0r> Indeed. I will give it a go.
[15:22:27] <Loetmichel> miss0r: classical case of "Grundig"
[15:22:52] <miss0r> I'm hoping it is on the power board, and not the controller itself. then I might as well give up.
[15:22:55] <Loetmichel> "Gründlich Ueberall Nachlöten Dann Ists Gut!"
[15:23:04] <miss0r> Hell, a refurbished controller card for it is only ~8000eur
[15:23:24] <Loetmichel> (throughly and all resolder then its good again)
[15:23:50] <miss0r> hehe
[15:23:53] <miss0r> I will give it a go.
[15:24:30] <miss0r> But it makes 'some' sense that is is on the power board - the error the HMI reports is "missing x/y axis phase wire"
[15:24:52] <Loetmichel> Grundig was a german company that in the 80ties decided to cut costs on solder
[15:25:04] <miss0r> I know Grundig all too well
[15:25:04] <Loetmichel> for their TVs
[15:25:09] <miss0r> I had a grundig tv...
[15:25:11] <miss0r> :D
[15:25:14] <Loetmichel> with the above effects ;)
[15:25:36] <Loetmichel> hmmm
[15:25:38] * miss0r is gathering strength for the resolder process.
[15:25:57] <Loetmichel> does the drive have IDC cables between the boards?
[15:26:00] <miss0r> Tell me; would you guys think it enough to just heat the existing solder + add a little more with a flux core?
[15:26:10] <Loetmichel> if so: have you tried to "re-press" them?
[15:26:13] <fragalot> miss0r: usually, yes
[15:26:22] <Loetmichel> i have seen those connections go bad over the years
[15:26:22] <miss0r> Loetmichel: re-press?
[15:26:41] <miss0r> as in the connectors?
[15:26:42] <Loetmichel> unplug the cables, press the plugs in a vice
[15:26:51] <miss0r> I have not
[15:26:54] <Loetmichel> so they reseat/cut the cable again
[15:26:56] <CaptHindsight> miss0r: that is what we used to do, add new solder to old joints
[15:27:05] <miss0r> But the PSU is two busbars - they are bolted
[15:27:46] <CaptHindsight> miss0r: this was the through hole days
[15:27:57] <miss0r> the power board is also though hole
[15:28:05] <miss0r> the controller is a whole new can of worms
[15:29:45] * miss0r is uploading photos
[15:30:43] <fragalot> miss0r: do you have a part#?
[15:31:21] <miss0r> its a simodrive lt-module 2x15A
[15:32:00] <fragalot> these guys have used in stock & offer repairs on those https://www.abcparts.be
[15:32:20] <miss0r> https://imgur.com
[15:32:29] <fragalot> i've talked to them quite a few times on tradeshows, from what i've gathered they seem to know what they're doing
[15:33:02] <miss0r> That is good to know.
[15:33:05] <fragalot> yea just resolder the lot
[15:33:07] <fragalot> :D
[15:33:14] <miss0r> Should this repair not work, I will contact them
[15:33:29] <miss0r> but I wouldn't mind being able to pull this off over night - that looks good on the resume :)
[15:33:35] <fragalot> :-)
[15:34:34] <miss0r> I wonder what my chances are, that the tap-a-tap-tap on the side was showing a defect on the power board, and not some micro vibrations in the motor cables ect..
[15:34:41] <miss0r> or even worse - the controller
[15:34:49] <fragalot> 33%
[15:34:51] <fragalot> :D
[15:34:59] <miss0r> lol thanks
[15:35:12] <fragalot> if you don't have a 2nd set to compare or swap parts around, a defect could be anywhere
[15:35:14] <miss0r> I don't suppose I get to keep those odds if I list a few more options?
[15:35:30] <fragalot> no
[15:35:33] <miss0r> :D
[15:35:38] <CaptHindsight> "was able to solve major manufacturing delay overnight"
[15:36:02] <miss0r> I actualy have a machine quite like this, standing next to it, with simylar issues
[15:36:20] <fragalot> but most electronics repair is literally just resoldering joints & replacing parts that look like they shat themselves, or run hotter than they should
[15:36:20] <miss0r> fragalot: By the way; the replacement board for the safety relay worked a charm
[15:36:43] <fragalot> oh good i'm glad it wasn't a critical part
[15:36:46] <fragalot> :D
[15:37:07] <miss0r> hehe - it is not used as such - then I wouldn't replace the innerts :D
[15:37:25] -!- emsjessec has quit [Read error: Connection reset by peer]
[15:37:29] <miss0r> I should just stick to calling it a redundant relay
[15:37:44] <fragalot> they're only redundant if there is a feedback loop signalling one has failed
[15:37:50] <CaptHindsight> "solved critical manufacturing issue with bare hands"
[15:37:54] <miss0r> Nothing looks like its ever been above room temperature in there.
[15:38:17] <fragalot> probably hasn't, but it's likely to have seen a lot of vibration
[15:38:30] <fragalot> so either the cable, or the solder joints are possible to have microfractures
[15:38:30] <miss0r> CaptHindsight: Indeed. I can see the yellow star stickers the boss of the factory will insert next to my name in his little black book :)
[15:38:41] <CaptHindsight> gold stars

[15:40:06] <CaptHindsight> "solved critical manufacturing issue with bear hands"
[15:40:43] <miss0r> solving anything with bear hands in impressive, unless it is catching salmon directly out of a stream

[15:59:14] <fragalot> like I said, not that expensive
[15:59:19] <CaptHindsight> the problem is usually moving them
[15:59:51] <CaptHindsight> some body here had one they we going to convert
[16:00:07] <CaptHindsight> was in Atlanta area, built and flew planes
[16:00:22] <CaptHindsight> had a laser mishap
[16:00:31] <CaptHindsight> whatever happened to him?
[16:00:46] <fragalot> no idea
[16:01:24] <SpeedEvil> I thought you said he had a LASER mishap.
[16:01:47] <CaptHindsight> SpeedEvil: minor fire, just the top floor
[16:02:09] <fragalot> colleague of mine outsourced some copper parts to a laser shop once
[16:02:17] <fragalot> turns out that the laser they used does not like copper
[16:02:28] <fragalot> also turned out to be a brand new machine, less than a week old
[16:02:34] <fragalot> ._.
[16:02:52] <SpeedEvil> :)
[16:03:05] <methods_> ouch
[16:03:12] <methods_> yeah co2 lasers can't cut copper or brass
[16:03:13] <CaptHindsight> tan from the sun :) https://www.ebay.com
[16:03:17] <methods_> or not for very long at least
[16:03:37] <methods_> our new fiber laser will however cut up to 3/8" copper and brass which is really cool
[16:03:48] <fragalot> methods_: he explained it apparently acted like a "perfect mirror" & just reflected the full beam right back up where it came from
[16:04:21] <methods_> yeah
[16:04:28] <CaptHindsight> know your wavelengths!
[16:04:37] <methods_> it's not a good thing to do to your laser
[16:04:37] <SpeedEvil> Phase conjugate mirrors FTW
[16:04:52] <CaptHindsight> or use fancy optics
[16:05:03] <fragalot> CaptHindsight: this is why some things get outsourced to people that are expected to know better than you do :P

[16:06:51] <fragalot> miss0r: you done yet? :P
[16:06:58] <CaptHindsight> https://www.ebay.com
[16:07:14] <CaptHindsight> never worked with software for those
[16:07:57] <CaptHindsight> can you make a punch a standard and them use it to punch larger holes?
[16:08:26] <CaptHindsight> in nibble mode
[16:08:32] <fragalot> on some machines
[16:08:53] <methods_> yes
[16:08:56] <CaptHindsight> say you have a range of round holes
[16:09:17] <methods_> a lot of them have rotating holders too
[16:09:28] <methods_> so they can punch and roll in any direction with the sheet
[16:09:40] <fragalot> yeah they're fun machines. kinda underrated
[16:09:44] <gloops> id think it would be difficult to keep a circular shape, if thats a necessity
[16:09:55] <fragalot> some of them can even roll form beads into the sheet metal
[16:10:13] <CaptHindsight> can you just use say a 5mm dia to make 6-25mm dia holes?
[16:10:14] <fragalot> gloops: sheet metal punches nibbling something out are more for approximate shapes than exact holes
[16:10:19] <fragalot> CaptHindsight: yes
[16:10:24] <gloops> right
[16:10:31] <methods_> https://www.youtube.com
[16:10:34] <fragalot> it'd be ragged, but it would do it fine
[16:10:59] <CaptHindsight> fragalot: do you have to use the machines controller to do that or is that done before in CAM?
[16:11:30] <fragalot> CaptHindsight: i've only ever used our sucontractors machine once, he just does everything on the machine
[16:11:52] <fragalot> pretty sure he has never done any CAM & runs all his machines right from their controllers
[16:12:52] <methods_> definitely easier to do in cam
[16:13:01] <fragalot> and with the speed at which that guy rams the parameters in, I think you'd be hard pressed doing it faster in CAM for the type of work we ask him to do
[16:13:03] <methods_> just load up the turret and auto tool
[16:13:04] <CaptHindsight> been thinking about converting some machines here to sheet metal forming
[16:13:36] <methods_> you really need to do a lot of chassis work with lots of holes or special form tools before turret punch makes sense anymore
[16:13:46] <methods_> lasers are just so much faster
[16:14:04] <CaptHindsight> but for one offs
[16:14:06] <fragalot> are they still faster if you need to do large hole patterns?
[16:14:36] <fragalot> lasers are certainly a lot more versatile, but imho punches still have their place
[16:15:28] <CaptHindsight> lasers can't form a rib
[16:15:49] <fragalot> not with that attitude
[16:16:00] <CaptHindsight> do you just need holes or some forming?
[16:16:36] <CaptHindsight> laser and prayer for metal forming
[16:16:39] <fragalot> we only need holes, some hex shaped for inserts, or square for HMI's, round for buttons, etc
[16:17:27] <fragalot> punches can't do this though. https://www.youtube.com
[16:17:44] <CaptHindsight> similar here plus some DB connector shapes
[16:18:20] <CaptHindsight> but have been thinking about CNC forming for short runs of obsolete sheet metal parts
[16:18:33] <CaptHindsight> say old cars
[16:19:28] <CaptHindsight> vs hammer, English wheel and lots of welding, grinding polishing
[16:20:27] <fragalot> that'd be an interesting project
[16:21:39] <CaptHindsight> https://youtu.be
[16:22:15] <methods_> methods_> you really need to do a lot of chassis work with lots of holes or special form tools
[16:23:22] <methods_> it's much easier to put a lower skilled person on a laser too
[16:23:34] <methods_> the learning curve for a turret punch is quite a bit steeper
[16:23:54] <CaptHindsight> https://youtu.be example application
[16:24:00] <methods_> sharpening tools, choosing die/punch clearance, loading/unloading tooling
[16:24:04] <fragalot> don't worry just put the top & bottom dies in at random & pray
[16:24:29] <methods_> lol
[16:24:40] <CaptHindsight> they eventually meet at some mutual shape :)
[16:24:54] <methods_> believe me i've had to unstick my fair share of punches put in the wrong way after some moron came back from lunch high as a kite
[16:25:09] <methods_> cross loaded punches are hell
[16:25:30] <CaptHindsight> imagine you scan the metal part required with your phone....
[16:25:36] <CaptHindsight> send the scan in.........
[16:25:52] <CaptHindsight> the part gets formed and shipped to you the next day

[17:57:36] <Tom_L> they have a form
[17:57:43] <Tom_L> so does a hydropress
[17:58:07] <CaptHindsight> hydropress has a form
[17:58:19] <CaptHindsight> SPIF has just a tool path
[17:58:33] <Tom_L> i didn't see the fixture til just now. he just mentioned all you need is a form

[17:59:43] <Tom_L> hydropress is definitely quicker
[17:59:51] <CaptHindsight> old car parts seems like a great fit
[18:00:22] <Tom_L> depends how much the metal stretches
[18:00:30] <CaptHindsight> any application that uses forming for production
[18:00:40] <CaptHindsight> but you only need 1 to few
[18:00:42] <Tom_L> you'd have to work out your path so it didn't work harden and tear
[18:01:32] <Tom_L> they still have springback
[18:02:03] <CaptHindsight> https://www.youtube.com
[18:02:13] <Tom_L> i think we allowed 2-3 degrees on the sides of the hydroblocks typically
[18:03:03] <CaptHindsight> https://youtu.be
[18:04:02] <Tom_L> i'm not real sure why the even need the spindle on there
[18:04:27] <CaptHindsight> https://youtu.be heat shields for exhausts
[18:04:44] <CaptHindsight> the first thing that rusts and gets thrown away
[18:05:05] <pink_vampire> I love PVC
[18:05:15] <CaptHindsight> i have an old EDM I might convert, no spindle
[18:05:45] <pink_vampire> keep the EDM an EDM
[18:06:29] <CaptHindsight> was an EDM, now it's just 3-axis with no tools
[18:08:19] <Tom_L> they've been doing that on lathes for years
[18:08:29] <Tom_L> makes sense to use a mill

[18:22:49] <andypugh> Cool punch. Also does bending and swaging: https://www.youtube.com
[18:23:15] <andypugh> Oh, and tapping.
[18:26:15] <andypugh> I just recieved my granite square from China.
[18:26:31] <andypugh> I wonder why they felt the need to coat it in rust-proofing oil?
[18:28:38] <CaptHindsight> granite rust is difficult to remove :)
