There's a Japanese Gameshow called Supreme Skills, where they set a challenge to an EDM and a lathe to drill through a 6cm long 0.5mm thick pencil lead. It was impressive as hell.
I worked for around a year on wire EDM, almost the same model as Mitsubishi in this video when I started my career (together with CNC mills) and I really like working on that. I made a cube made of four puzzles like that. It's so satisfying.
I believe the number he gave was "five thousandths", so 5/1000, not 1/5000. If you remember that there are 25.4 millimeters in an inch, you should be able to approximate the conversion in your head pretty easily. (It actually ends up being close to 1/5000 in inches since there's about two factors of 5 in the conversion.)
I've worked with Mitsubishi Wire Feed edms (FA20S) myself, and I honestly find them very satisfying to work with. I used to primarily program and run the machine for tool & die components, but I loved to find an excuse to whip out the machine for other use cases that conventional machining methods would be difficult. I have far more experience on milling and lathe work now, from anywhere from micro-machining to huge oil and gas components, but its nice to see wire edm in action as it was essentially my roots beginning as a machinist. Thanks for showing off my passion for others to see, I find this stuff fascinating with the history and science of manufacturing, and how it allows humans to make amazing innovations. A few little tidbits I thought I might mention in case you might be reading this: when referring to the .001's place of a millimeter, it is preferred to say "Microns" as it makes you sound smarter, but also it prevents confusion from the imperial "thousandth's" which is commonly used as it's own term. The first type of edm you mentioned, the sinker type, was far more common decades ago as wire feed edm was not advanced enough at the time. While the accuracy of a EDM machines is amazing, they are not the only machines that can reach such levels of repeatable precision even down to +-.005 millimeters, however, they are set apart by the unique features they are able to cut as they exert very little cutting forces, and the difficult to cut materials that they superior at dealing with. Modern diamond tooling solutions try to give other machine tools access to manufacturing these types of extremely difficult to cut materials, such as tungsten carbide, but EDM machines are a tried and true method that many shops still rely on for tool & die or other prototyping manufacturing. Thank you for your informative video, I have not touched a wire edm machine in a year and I honestly miss the joys of working with them, or having your wire break midway through a 18 hour die and accidentally resetting your G54.

I've seen videos of F-22s and B-2s refueling in midair. One of the craziest parts of it is that the port for refueling seems to appear from nowhere. The nature of stealth aircraft is that you really can't have even small ridges otherwise you've compromised your stealth, so the closed port needs to be perfectly hidden with no visible seam. I wonder if it's the same process being used.

In a 'former life' worked on EDM machine that was used to remove broken studs from machine blocks etc. I always thought it was amazing how they could 'bore' out the broken stud, large enough to cut the stud from it's own threads (diameter of the thread root) and yet NOT damage the threads cut into the hole of the machine block. Some very precise stuff.
Well, one can cut to tighter tolerances, using similar methods. But, then one has to worry about sticktion, the damned thing welding itself while static and assorted other annoyances.
One note about the process, the voltage actually isn't very high. The wire EDM machines we have at work run at around 40 volts. The amperage is quite high however and would instantly overheat and break the wire if it weren't submerged. You can also stick your hands in the tank while the machine is running with no worries of electrocution because the deionized water is such a good insulator.
Wire erosion _can_ be very accurate, if well calibrated and with the proper settings... I've personally had wire eroded parts delivered well out of tolerance before - it's like any other CNC machine in some respects. One of the really cool things about wire erosion, aside from the sorts of details and features you can make with it, is you can put very neat cuts through incredibly tough materials that traditional machine tools would really struggle with: hardened tool steel, nickel superalloys, tungsten etc.
Hilarious! That one-liner had me in stitches. It's the unexpected humor that truly brightens our days. I couldn't help but laugh out loud. Keep those witty moments coming, they bring so much joy. 😂👏🎉
Ya know, I just bought a safety razor about 2-4 weeks ago, and after a small learning curve I love it far more than any proprietary multi-bladed razor I've ever used. Glad to see you on the old school train, Steve
It's a bit tricky, but definitely worth it! It sounds cheesy, but combine it with a nice soap and brush and it transforms shaving from a chore into a fun ritual
The trick is that he completely shaved a copy of his face, cut it and glued it onto his first face, the n gave it a polishing pass so it looks like a single face.
I just want to comment how refreshing this is to have a channel that is educational, clever and interesting among the huge crap that has become the internet.
Yeee, have worked on CNC machines for around 7 years (+ 3,5 years training + 3 years in the office programing for such machines) and some of the tolerances were almost unbearable, especially when it came to things that were hard to work on...like special materials or long and small stuff, like for the production of medical stuff for blood draws and so forth.

I had a WIRE EDM shop for 18 years. Did this type of work every day. It's been 20 years would love to know what cutting speeds are now. Back then 12 inches an hour was fast.
i think you would know im a mold maker and ran sinker EDMs from the Pacific's from the 70s to the more modern cnc edm the speed increase is night and day
@jacquelinesears1770 I also started out as a mold maker. That's when I began to specialize in sinker EDM. I ran a Charmilles D10. Then, I went to work for AGIE, where I learned wire EDM. Bought a wire machine from AGIE, and the rest is history. My first employee was a woman she could do it all.
Genuinely thank you for making a video on machining stuff. We have so few people entering the work force and I hope this video inspires some kids to pick up the trade.
An amazing video. Quick word to anyone thinking of getting the razor. I bought a safety razor 17years ago and never looked back. 100 blades for about £10 and as Steve showed, you can take off days of stubble on one pass. Took the wife a little time to work out how to do her legs but she's got her own new. Regardless of what brands you buy its cool you can be environmentally minded, have a better product and it's cheaper
I remember when I was a kid, we'd get home from the grocery store and all gather around the table to drill holes n the cheese. Is that not a normal family activity?
1:49 I love how he went to the effort to drill a hole and feed a wire through the cheese, only for it to split in the corner immediately as he tried to cut it
I always thought of the possibility of invisible seams after seeing loads of cartoons on TV as a child where a trap door would open in a metal floor or a door etc. And thought "I wonder how possible it'd be to actually conceal a door in that way." But not with those exact words 😅
My dad works with wire EDM at his work, it's amazing to see just how PRECISE the cuts are. Literally within thousandths of a millimetre. In fact, i believe the cuts he makes at his workplace are even more precise than shown in the video. It's an outstanding piece of machinery.
I don't know if it was mentioned or shown in this video, but I believe you cut out the hole on main work piece. Then, on a separate piece, you cut out the plug, so it will sit super tight
My previous company used a custom developed wire EDM process to cut dozens of slots with micron-level accuracy, for use in electrical shavers. At some point they moved to newer techniques, but until a few months ago, these processes where still used for the low-end market and ran for decades. Very cool and robust process!
I didn't know how much I needed to see the end results of a wire EDM until I saw this video on my frontpage. Your explanation of the process really makes it clear that an amazing end result needs an amazing process.
I purchased 2 of these MetMo Cubes back when they were 500+ USD each and I LOVE them to this day :D They're now a lot cheaper, nearly half-off... WOW! Please consider purchasing your own you sooo won't regret it hahaa... i strongly believe in this company's products and want to see what else they come up with :D
My old man told me the story of his engineers apprenticeship (1930s)when an exam required him to make an octagonal block and octagonal key. His tutors informed him that the finished piece was an incredible 99% mark awarded. He went on to become a principle examiner in the patent office.
These blocks and your old man's apprenticeship reminded me of my apprenticeship, back in 1984! We had to cut a 2 inch cube of steel across the diagonal BY HAND (it took about two weeks!), then hand-finish the surfaces using a technique I don't remember the name of. In the end we had made ourselves a 'lifting block', which still works to this day! As it's kept carefully wrapped in oily paper the surface has been preserved thankfully! Certainly something to hand on to the grandchildren (when they arrive!)
@@stepheneyles2198 was it hand scraping? Kinda a long chisel-like thing and you end up getting a really unique looking finish pattern that's almost iridescent? Seems like it would be the kind of technique to incorporate on a masterpiece project.
@@JohnDlugosz It sounds like this could be some odd name for a Gauge Block considering the apparent need for precision, storage conditions, and mention of the surface finish of the face being important.
I remember being very disappointed when I learned EDM works in two steps. It really removed the mysticism of the process and just turns it into "it's very precise" which has it's own merits but it's just not the same as thinking it's a single step.
@@volvo09 Eh, wouldn't have much of an impact. What would be really cool would be two things: cheap, sustainable electricty (doesn't use a very limited resource as fuel and doesn't excessively pollute) and perfect recycling technology. We really need the former for the latter to be viable, otherwise it's economically unviable.
@@Fantastic_Mr_Fox ... Are we reading the same comment?. The "waste material" they mention is the material lost in the cuts. If one wanted to have the inner piece to come from the same location of the hole as the original comment described, the cut would have to have practically no width, removing an imperceptible amount of material at best and also not deforming the metal like a stamping process does. This is impossible with current manufacturing techniques and will be for decades, at least in metal. Nothing to do with recycling or whatnot.
@@Shelleloch I know, I'm just saying that in terms of actual waste it wouldn't matter much. I made a tangentially related comment about waste recycling, if you will. But yes zero waste manufacturing would be hella cool, not because of the zero waster part but because of the 100% accuracy part.
Pretty cool. The "tricks" were pretty clear just from looking at the end result. I didn't know about Wire EDM though. I was wracking my brain trying to figure out how they got such precision with a CNC mill.
This channel helps preserve that child like curiosity. I'm 35 and for years now I'm always smiling seeing new video. Part of it is obviously chosen topic but Steve is arguably the most important thing here. I mean guy's hot wiring a cheese and somehow it's not only incredibly interesting but is teaching a lot. He's a perfect 90's children science tv program host. And it's 90's specific because back then science programs were actually designed for all ages and in some cases like in my country "health and safety" were only considered when you WILL actually die if you dont use let's say rubber gloves.
its actually crazy how long we've had this kind of precision, i'm not sure exactly when wire EDMs became a thing but i know that at my machine shop, we have a wire EDM from 1986 that still holds fairly good precision, yeah the ball screws are a little worn out from machine travel over the years but for never being replaced, we still hold .0005 inches tolerance with that old dinosaur
Die EDM has been around since the 1940s. I believe wire EDM was developed back in the 1960s. There is also photo etching maching which is used to make very very small precision parts.
@@guytech7310Photo etching is still used for making electronic parts with insanely high precision, 1000 times tighter than EDM in the latest factories .
Interference fits are the worst. You never know and you should not really try either lol. Like if this piece had just a tiny fit, it would never come out.

6:52 steve your humor is getting better each time, i laughed many times throughout this video, definitely more than once! that was amazing. edit: the comedic time is getting way better too, the cut after the inches joke was perfectly made, with the level of precision as great as the ones in the metal.
Absolutely fascinating stuff, thanks Steve! As soon as I saw the razor connection I thought you'd missed a trick by not using that as a sponsored segment - absolutely seamless segue by the way, a work of art!
Great video. And as a long-time shaver who uses double-edge safety razors, you are absolutely right about Henson Shaving's razors. I have two - AL13 and AL13M - and both are excellent. Extremely good design: if you don't have the right angle, nothing happens. (With most DE razors, if you don't have the right angle, you get a nick.) The Henson Shaving razor is both extremely comfortable and extremely efficient. I do recommend using a good shaving soap and a shaving brush rather than canned foam: that makes a big difference, even with a cartridge razor.
I am currently in engineering grad school and I use EDM for my research! I test the fracture toughness of additively manufactured alloys, and I use EDM to cut a very narrow crack into the specimens I test. We use a wire that is about 100 microns (0.004 in.) thick, and it gives us a crack width of less than 110 micron. So very cool to see Steve talk about it. Our machine isn’t as fancy as the one in the video. It doesn’t tilt the wire for one, but it’s good enough for our purposes.
Interesting. I made some things like that as toys during my decades in machine shop. You can hold some pretty close tolerances with conventional equipment if you're careful. Working in a controlled environment I was able to hold .00005" diametric tolerances on a Hardinge Toolroom CNC.
1:46 "You first drill a hole in the cheese, we've all done it" I don't know why but that line & dry delivery made me SCREAM with laughter. Like, we had to pause the video and I had to forcibly calm myself down bc I was starting to scare the cats 🤣🤣🤣
Really cool! I've seen videos about these sorts of precision cut blocks of metal before, and I looked briefly into wire edm, but I'm glad you explained it more concisely. You're probably my favorite educational youtuber, and I watch MANY.
Great shots and demonstrations with the cheese! One nit about the styrofoam wriggle room: that one's likely because you're cutting it by sublimating a bunch of the material with a hot wire, so a decent portion of it simply doesn't exist anymore, and that would happen on the outer edge and inner edge, causing a good amount of lost material.
Will definitely look back on this video as the point where Mould started spinning out of control with his "everything can be demonstrated with cheese" mental abyss. All the great ones go insane.
I've been really curious about those invisible seam metal pieces. I've been seeing them a lot in damascus knife forging videos (some absolutely insane effects can be achieved that way). Love your videos and thanks for the new info ❤️
6:45 "A typical wire edm machine will have a precision of about 5000th's of an mm, which in inches is a different number" Steve Mould 2023, also did anyone notice how he shaved half of his beard at the end of the video?😳
The gap at 2:50 actually corresponds to to the diameter of the wire plus two times the spark gap, i.e. the distance the dose to jumps. The spark gap is small, but for this level of precision, it will be taken into account.
Awesome precision and how the wire edm works. A scroll saw with a spiral blade can make similar cuts in wood that aren't possible with a conventional flat blade. I have a video of a set of nesting helixes that are all cut from the same cylinder, the inside pieces are removable and are completely enclosed except for a thin slot along the edge - no gluing involved. I think it would be really cool to make one with a wire edm machine from metal. Keep up the great videos!

6:50 "A typical wire EDM machine will have a precision of around a 5000th of a millimetre, which in inches is a different number" 😂
I came here to say this but you beat me to it😂
I think he meant 5 thousandths, not 1 five-thousandth.
0.00019685 inches
The length of the right side of his stubble is the same number as the left side. They’re just different units.
I believe the number he gave was "five thousandths", so 5/1000, not 1/5000. If you remember that there are 25.4 millimeters in an inch, you should be able to approximate the conversion in your head pretty easily. (It actually ends up being close to 1/5000 in inches since there's about two factors of 5 in the conversion.)
I've worked with Mitsubishi Wire Feed edms (FA20S) myself, and I honestly find them very satisfying to work with. I used to primarily program and run the machine for tool & die components, but I loved to find an excuse to whip out the machine for other use cases that conventional machining methods would be difficult. I have far more experience on milling and lathe work now, from anywhere from micro-machining to huge oil and gas components, but its nice to see wire edm in action as it was essentially my roots beginning as a machinist. Thanks for showing off my passion for others to see, I find this stuff fascinating with the history and science of manufacturing, and how it allows humans to make amazing innovations.
A few little tidbits I thought I might mention in case you might be reading this: when referring to the .001's place of a millimeter, it is preferred to say "Microns" as it makes you sound smarter, but also it prevents confusion from the imperial "thousandth's" which is commonly used as it's own term.
The first type of edm you mentioned, the sinker type, was far more common decades ago as wire feed edm was not advanced enough at the time. While the accuracy of a EDM machines is amazing, they are not the only machines that can reach such levels of repeatable precision even down to +-.005 millimeters, however, they are set apart by the unique features they are able to cut as they exert very little cutting forces, and the difficult to cut materials that they superior at dealing with. Modern diamond tooling solutions try to give other machine tools access to manufacturing these types of extremely difficult to cut materials, such as tungsten carbide, but EDM machines are a tried and true method that many shops still rely on for tool & die or other prototyping manufacturing.
Thank you for your informative video, I have not touched a wire edm machine in a year and I honestly miss the joys of working with them, or having your wire break midway through a 18 hour die and accidentally resetting your G54.
I think you meant "down to ±5 microns" 🙂

it's not for everyone though: some alloys are as hard to work with as they are delicious
Cheese welding is good too, lots of skill and patience required though!

Some very precise stuff.

@@4f52 Maybe he just didn't like it, was tiring, didn't pay well, stuff like that, Mark Rober quit being a NASA engineer to be a youtuber.
Well, one can cut to tighter tolerances, using similar methods. But, then one has to worry about sticktion, the damned thing welding itself while static and assorted other annoyances.
One note about the process, the voltage actually isn't very high. The wire EDM machines we have at work run at around 40 volts. The amperage is quite high however and would instantly overheat and break the wire if it weren't submerged. You can also stick your hands in the tank while the machine is running with no worries of electrocution because the deionized water is such a good insulator.
People really underestimate how much of a resistor pure water is.
this would be a good way to hide stuff. like sneaking things on an airplane
... and it is only 40V, as you just said. Nobody ever was electrocuted with 40 V...
@@Blox117w... what are you planning to do with this info
Would the water stay deionized if you put your hand into it, though. 😂
Wire erosion _can_ be very accurate, if well calibrated and with the proper settings... I've personally had wire eroded parts delivered well out of tolerance before - it's like any other CNC machine in some respects.
One of the really cool things about wire erosion, aside from the sorts of details and features you can make with it, is you can put very neat cuts through incredibly tough materials that traditional machine tools would really struggle with: hardened tool steel, nickel superalloys, tungsten etc.
it'd be very easy to make stuff like 123 blocks this way too. just grind in one dimension and let the machine handle the rest of it
I mean your first point is literally true for everything.

@@All_SportGG Just a guess on my part. But I think the brass wire mostly carries the electric charge which is actually doing the cutting.

Just what all men truly desire. Beautiful and *super tight* .

Yeee, have worked on CNC machines for around 7 years (+ 3,5 years training + 3 years in the office programing for such machines) and some of the tolerances were almost unbearable, especially when it came to things that were hard to work on...like special materials or long and small stuff, like for the production of medical stuff for blood draws and so forth.

I had a WIRE EDM shop for 18 years. Did this type of work every day. It's been 20 years would love to know what cutting speeds are now. Back then 12 inches an hour was fast.

@jacquelinesears1770 I also started out as a mold maker. That's when I began to specialize in sinker EDM. I ran a Charmilles D10. Then, I went to work for AGIE, where I learned wire EDM. Bought a wire machine from AGIE, and the rest is history. My first employee was a woman she could do it all.
Its my wife's account i am a mold maker her husband sorry about that @@patrickturner2788
Genuinely thank you for making a video on machining stuff. We have so few people entering the work force and I hope this video inspires some kids to pick up the trade.
An amazing video. Quick word to anyone thinking of getting the razor. I bought a safety razor 17years ago and never looked back. 100 blades for about £10 and as Steve showed, you can take off days of stubble on one pass. Took the wife a little time to work out how to do her legs but she's got her own new. Regardless of what brands you buy its cool you can be environmentally minded, have a better product and it's cheaper
Yep. Buy a safety razor, better in every way. Multi stage disposable razors are a masterful display of capitalist innovation.

"Which in inches is a different number." Has to be one of my favourite comments on UA-cam for at least a few months! XD
Wire EDM was all the rage in the early 2000's club scene.
I always thought of the possibility of invisible seams after seeing loads of cartoons on TV as a child where a trap door would open in a metal floor or a door etc. And thought "I wonder how possible it'd be to actually conceal a door in that way." But not with those exact words 😅
You know all those cartoons were based on Chicago's Hotel of Horrors. Look it up. The guy even had paintings with holes in the eyes to watch people.

You did notice those blocks have a wire- brushed surface ? Helps to conceal joint lines.
@@antoniograncino3506 Of course we all did.
The "portable hole" in a bugs bunny cartoon always intrigued me from a young age.
If the clearance is so tight, whats stopping the metals from cold-welding into each other and fuse?
Cold welding only works for ductile metals, not carbon steel.
My dad works with wire EDM at his work, it's amazing to see just how PRECISE the cuts are. Literally within thousandths of a millimetre. In fact, i believe the cuts he makes at his workplace are even more precise than shown in the video. It's an outstanding piece of machinery.
Wow
I don't know if it was mentioned or shown in this video, but I believe you cut out the hole on main work piece. Then, on a separate piece, you cut out the plug, so it will sit super tight
@@jakefriesenjake yeah it’s something like that, im not 100% familiar with the technology but it truly is incredible stuff
My previous company used a custom developed wire EDM process to cut dozens of slots with micron-level accuracy, for use in electrical shavers. At some point they moved to newer techniques, but until a few months ago, these processes where still used for the low-end market and ran for decades. Very cool and robust process!
I didn't know how much I needed to see the end results of a wire EDM until I saw this video on my frontpage. Your explanation of the process really makes it clear that an amazing end result needs an amazing process.
I purchased 2 of these MetMo Cubes back when they were 500+ USD each and I LOVE them to this day :D They're now a lot cheaper, nearly half-off... WOW! Please consider purchasing your own you sooo won't regret it hahaa... i strongly believe in this company's products and want to see what else they come up with :D
My old man told me the story of his engineers apprenticeship (1930s)when an exam required him to make an octagonal block and octagonal key. His tutors informed him that the finished piece was an incredible 99% mark awarded. He went on to become a principle examiner in the patent office.
These blocks and your old man's apprenticeship reminded me of my apprenticeship, back in 1984! We had to cut a 2 inch cube of steel across the diagonal BY HAND (it took about two weeks!), then hand-finish the surfaces using a technique I don't remember the name of. In the end we had made ourselves a 'lifting block', which still works to this day! As it's kept carefully wrapped in oily paper the surface has been preserved thankfully! Certainly something to hand on to the grandchildren (when they arrive!)
@@stepheneyles2198 was it hand scraping? Kinda a long chisel-like thing and you end up getting a really unique looking finish pattern that's almost iridescent? Seems like it would be the kind of technique to incorporate on a masterpiece project.

I remember being very disappointed when I learned EDM works in two steps. It really removed the mysticism of the process and just turns it into "it's very precise" which has it's own merits but it's just not the same as thinking it's a single step.
The technology to practically have no waste material would be incredible.
@@volvo09 Eh, wouldn't have much of an impact. What would be really cool would be two things: cheap, sustainable electricty (doesn't use a very limited resource as fuel and doesn't excessively pollute) and perfect recycling technology. We really need the former for the latter to be viable, otherwise it's economically unviable.
@@Fantastic_Mr_Fox ... Are we reading the same comment?. The "waste material" they mention is the material lost in the cuts. If one wanted to have the inner piece to come from the same location of the hole as the original comment described, the cut would have to have practically no width, removing an imperceptible amount of material at best and also not deforming the metal like a stamping process does. This is impossible with current manufacturing techniques and will be for decades, at least in metal.
Nothing to do with recycling or whatnot.
@@Shelleloch I know, I'm just saying that in terms of actual waste it wouldn't matter much. I made a tangentially related comment about waste recycling, if you will. But yes zero waste manufacturing would be hella cool, not because of the zero waster part but because of the 100% accuracy part.
A lot of EDM is dubstep.
This is a joke.
I love that we have footage of Steve (or really, any human) ironing cheese 😂
that's actually a sander. some of them are shaped like irons, presumably so that you can sand the insides of sharp corners

@@jamesorendorff2284 Also referred to as a mouse sander, which coincidentally works well on cheese :P But please don't sand a mouse with it.
Specifically, that's a Parkside detail sander from Lidl. Probably the same place he bought the cheese.
Pretty cool. The "tricks" were pretty clear just from looking at the end result. I didn't know about Wire EDM though. I was wracking my brain trying to figure out how they got such precision with a CNC mill.
This channel helps preserve that child like curiosity. I'm 35 and for years now I'm always smiling seeing new video.
Part of it is obviously chosen topic but Steve is arguably the most important thing here.
I mean guy's hot wiring a cheese and somehow it's not only incredibly interesting but is teaching a lot.
He's a perfect 90's children science tv program host. And it's 90's specific because back then science programs were actually designed for all ages and in some cases like in my country "health and safety" were only considered when you WILL actually die if you dont use let's say rubber gloves.
its actually crazy how long we've had this kind of precision, i'm not sure exactly when wire EDMs became a thing but i know that at my machine shop, we have a wire EDM from 1986 that still holds fairly good precision, yeah the ball screws are a little worn out from machine travel over the years but for never being replaced, we still hold .0005 inches tolerance with that old dinosaur
Die EDM has been around since the 1940s. I believe wire EDM was developed back in the 1960s. There is also photo etching maching which is used to make very very small precision parts.

Absolutely fascinating stuff, thanks Steve! As soon as I saw the razor connection I thought you'd missed a trick by not using that as a sponsored segment - absolutely seamless segue by the way, a work of art!
Great video. And as a long-time shaver who uses double-edge safety razors, you are absolutely right about Henson Shaving's razors. I have two - AL13 and AL13M - and both are excellent. Extremely good design: if you don't have the right angle, nothing happens. (With most DE razors, if you don't have the right angle, you get a nick.) The Henson Shaving razor is both extremely comfortable and extremely efficient. I do recommend using a good shaving soap and a shaving brush rather than canned foam: that makes a big difference, even with a cartridge razor.

I am currently in engineering grad school and I use EDM for my research! I test the fracture toughness of additively manufactured alloys, and I use EDM to cut a very narrow crack into the specimens I test. We use a wire that is about 100 microns (0.004 in.) thick, and it gives us a crack width of less than 110 micron.
So very cool to see Steve talk about it. Our machine isn’t as fancy as the one in the video. It doesn’t tilt the wire for one, but it’s good enough for our purposes.

Great shots and demonstrations with the cheese! One nit about the styrofoam wriggle room: that one's likely because you're cutting it by sublimating a bunch of the material with a hot wire, so a decent portion of it simply doesn't exist anymore, and that would happen on the outer edge and inner edge, causing a good amount of lost material.
The same would happen if you were trying to use wire EDM with the same method which is what he was showcasing.
So you’re telling me the impossibly thin cuts aren’t EVEN made
There are videos on DIY wire EDM's you can build at home. They're not as precise as commercial versions but still incredibly accurate.

Yes! Most people seems to have missed that.
Best quote I have heard in awhile, 'It's about 5 thousandths of a millimeter, and in inches a different number'. Love it. No idea why.
The gap at 2:50 actually corresponds to to the diameter of the wire plus two times the spark gap, i.e. the distance the dose to jumps. The spark gap is small, but for this level of precision, it will be taken into account.
Awesome precision and how the wire edm works. A scroll saw with a spiral blade can make similar cuts in wood that aren't possible with a conventional flat blade. I have a video of a set of nesting helixes that are all cut from the same cylinder, the inside pieces are removable and are completely enclosed except for a thin slot along the edge - no gluing involved. I think it would be really cool to make one with a wire edm machine from metal. Keep up the great videos!
