nice , but remember there are two separate pieces of metal that must be machined separately. It's not like the "cut out " piece is just sliding back in with zero tolerance. I know most people know this, but for some people they do think it's just the cut out piece being slid back in .
@beaconblaster33 maybe it would still look seamless since it deforms uniformly-but any strain in the frame of such a door makes what may be the most stuck door possible with zero tolerance!
Ive been running EDMs for 15yrs and its cool to see how different metals cut, different lengths of time,and power setting differences each have and will work well together, and the intricate things you can make. love running these things👍👌
@@bogart7498 What a stupid thing to say. I have worked with one of these as well. Do you understand how many people do this sort of work everyday? And why do you suppose this is on my feed ? Because I am interested and engaged with this sort of thing, of course people who do this watch this and are likely to comment. All you do is expose yourself as a very disaffected ignoramus.
Cnc kitchen just did a video at a maker fair that someone had a desktop edm. It was made out of common 3d printer parts so it should be affordable when they make it available to the public.
@@polychoronPeople (private and companies) use this process along with 3D printing to make firearms and related accessories like suppressors. Suppressors especially are illegal to own without paying for a $200 tax stamp and having a Federal Agent approve ownership. The BATFE (more commonly ATF) is in charge of “regulating” suppressors and dealing with those who own them illegally. A common “joke” is that if you make the ATF mad by having some fancy toy you aren’t supposed to (full auto, suppressor, short-barreled rife, etc.) they will shoot your dog. And since the wire EDM gives the ability to make complex designs, like modern suppressors have, he was making a joke that one could use this tech to make illegal suppressors.
@@gerardboles1124It’s not exactly a joke. If you looked up how many time it happens you would be disgusted. Not just the ATF but many police shoot a lot of innocent dogs. Especially when serving warrants they believe they can do anything as long as they have a warrant.
@@TheSchultinatorit’s because a lot of current is burning away iron atoms little by little when the wire touches the highest point of the surface. Imagine a lightning hitting the part and striking away material with a little explosion. The liquid they use is a non conductive (or a high resistance fluid) liquid called Dielectric(German:Dielektricum). Funfact: you could submerge electronics like your PC in that fluid and your would get one of the best cooling system.
@throwaway3873 Mineral oil is what most of the aquarium style builds use because then you just have to worry about capacitors, with distilled water there's the worry of ion contamination.
When she says shes the masochist to your sadist and y'all were made for each other like zero tolerance machining: "put ya money where my mouth is baby solve this Rubik's cube
Just to be clear, that rocket part looking thing was a metal 3d print that they cut in half with the wire EDM, it was not created on this machine, wire EDM is often used to remove metal 3d prints from build plates, in this case they were using it to cut it in half to show off how metal 3d printing can create internal structures in a way that really no other type of manufacturing can.
“Honey, I lost my cool motorcycle jacket cross made out of metal. Do you know what happened to it?” “Did you check the completely smooth block of metal in the living room that used to have a cutout of the cool motorcycle jacket cross?”
Because EDM (Electric Discharge Machining) is just super satisfying, as are its results. The technique you are seeing here is wire EDM: an electrically charged wire is pulled through the steel with arcs forming that erode away at the material. The voltage is specifically adjusted to only allow for a specific arc range and every conductive material within that radius around the wire gets eroded off. The machine is CNC guided and allows for extremely precise machining.
The closest thing to an asmr tingle I feel is from watching and listening to those beautiful metal parts slide into place and disappearing like nothing happened. I love every second of this, the springy op art looking piece at the end pleases me greatly. Thank you!
@@ChanceandChoicethere's only so much one can learn without access to the actual machine. Theory can teach you the basics, sure, but if you're actually in front of the machine it tells you so many things with how it looks, sounds or smells. It tells you if you're too fast or too slow, if you need more cooling or stabilization or if your part isn't clamped down correctly.
My tips: (1) Learn CAD/CAM. Bobcad is popular. Lots of online tutorials. (2) buy a small milling machine and CNC control box with xyz control. Maybe a few grand total. Great way to get familiar with G-code and machining basics. (3) When ready, go to waterjet instead of Wire EDM. They are cheaper to run, and use far less electricity. $20k or so.
@@andywolanA much cheaper way to learn & play around with g-code would be to buy a 3D printer. Which would be a recommendation that I would use for anyone not wanting to drop $10k+
Common name is an _interference fit._ The bearings in the inertial navigation gyro platforms I repaired use them. Bearing in the freezer & platform in the oven to assemble.
@@singleproppilot Yeah, the newer ones were all solid state, strapped down systems. The benefits of modern computing power! (The Delco CIVA had a whole 6kB of memory for program, data, & scratchpad. And it was based on the Apollo guidance system they built, according to Delco.)
The first segment is misleading. Those are two different cuts of metal. Not the same with a hole punched out. It doesn't matter what material, what thinness, what technique. There will always be missing material from the cut. Nothing's perfect.
The way these edm process vids show the pieces fitting together it gives someone, who doesnt know wtf is happening in the vid, the perception that it was all cut at the same time from one piece in one pass. @@Martin-xh1hd
Bridgeport made a optical line tracer in the 60s and this example was how they showed how accurate it was with two pieces of metal fitting together with no lines. Whats old is new again.
FYI - this is a thin strand of wire, electrified, run from one reel to another - like a band saw. Where is lit up, to look like a "laser", is where the wire has made contact with the piece being cut. Items that slide together need to cut two items A. The positive side and B. The negative side. A. Is the shape and B. Is the block that the shape slides into. In this video there are complex 3d printed metal items being cut in half.
@@jollymycology6391EDM means electric discharge machining and it works by an electrode made of material that won’t disintegrate touching the material which is basically burnt off (doesn’t actually burn because it’s submerged in a solution but it erodes and settles in the tank)
The wire doesnt touch the material the electrical spark jumps from the wire to erode the job it would be in short circuit and the machine would stop if the wire was in contact with the job
You know when you have an itch and you find the exact right spot to go after it when scratching it, and you get that "ooooo" face with a rolled eye or even a slight shiver cause "that was a good scatch". That was how my brain felt in the beginning with the part sliding back into the negative space. Good brain scratch. *spine shiver*
Should be zero CLEARANCE, but it’s not even that. They may be very, very small clearances, but not zero, or you would have to push the parts together with a hydraulic press.
I was an EDM operator. We made cardiovascular equipment pieces the size of grains of sand. Those darn things like to run off zero constantly at that small a size cut. Loads of wire issues too on our older ones. Now im an operations team lead but i still run EDMs when needed
I'm sorry doc, but meet the grahams It's just not disposable. It's a piece of art, we've never even seen beef track like that ever, the way its written, the way is executed, its just art
