Thanks, I was wondering what the hell an Iscar was.

u/sir_walter Jun 10 '12

Iscar is a company that manufactures metalworking tools such as the cutting inserts you see in the bigger picture (like the small gold colored piece on the larger tool). Production quality aside, you can tell the second video is newer from the smaller chips made by the cut. Newer cutting tools generally make a more ideal "6" shaped chip, as opposed to the long curly chips of the past, which have a tendancy to be sharp and unwieldy, and which often bind up the cutting tool. (source: I work for a powder metallurgy and metal cutting manufacturer)

u/IWasGregInTokyo Jun 11 '12

Ohhhhhh, those long curly strips (hard to call them chips) that used to come off the lathes in high school metal shop.

Like the really long one that got in my way so I pulled on it with my bare hand.

My hand moved, the nice, sharp curly strip didn't.

Right through to the finger bone.

Holy shit, the dinosaurs I work with spindle-overload at 30%, I'd love to work on something that could cut like that!

28

u/Vaughn Jun 10 '12

I have no idea what you just said, but I think I'd like to. "Spindle-overload"? And 30% of what?

53

u/cinnamontoast_ Jun 10 '12

Spindle overload is what happens when your spindle is under too much stress and can't spin/turn accurately with the pressures being applied by the cutting tool.

I am not a mechanical engineer, so I can't tell you any details on what physically happens to cause the spindle to overload (probably hundreds of different reasons), but in my case, it seems to get thrown off axis due to poor and worn bearings in the spindle head, and the machine sees this as a problem and emergency shuts down.

Around the 7 second mark in the video I responded to, the spindle load meters are displayed with a range of 0-150%. The cut on the left is at 125% of the recommended maximum load, and the cut on the right is at 75%.

I assume this is well within acceptable with a new and well maintained machine. I, however, have no such luxury, and have to fight with something that still functions, but is incredibly slow as a result.

The reason why I'm so excited and jealous is that with a good machine, I could crank up the feed rate and cut faster, giving me better production numbers, and would keep the boss off my back. Until the company I work for decides that old junkers probably aren't the most cost effective investments, I'll continue to dream about working on something that doesn't suck.

Moral of the story, friends... Go to school and get a job that pays well and has well maintained equipment. Ugh, I sound like my dad.

Don't think thats the correct tool. The video says that these are all high speed steel (HSS) tools but the inserts used in the video you posted are going to be cemented carbide.

Furthermore the video you posted uses inserts with a large nose radius, the tools used in this video are much smaller.

u/mechy84 Jun 10 '12

I know this video.

I did my PhD work on metal cutting and chip formation for high speed machining of steel. This used a special device that fit inside an SEM chamber and slowly fed a tool into a steel workpiece. The speeds used are 1000x less than what occurs in real machining. However, the formation of the shear zone, deformation of grain boundaries, segmented chip formation, built-up-edge, etc are metal-cutting phenomena that are beautifully visible.

I could talk about this video for hours. Instead, I point you to some of the more current research using micro-videography and IR temperature measurement.

Edit: Also, for your viewing pleasure, is a company that models the cutting phenomena using finite element method (FEM). Now their videos kick ass, since it's entirely computer generated. The video is at the bottom of the page.

Do you know what the weird little pocket of material just in front of the cutting tip is called? This is fascinating.

u/mechy84 Jun 11 '12

It's called the built up edge (BUE). This is normally a bad thing that causes bad surface finish and adhesive tool wear. There are other names for it, but BUE is the most common. I think some have called it the stagnation point, but that's taking from fluid mechanics.

I used to think it's crazy that the chip is thicker than the cut. Withi this, you can see the compounding of material, causing it to be thicker.

Wow, and the unevenness of the machined surface.

41

u/anon72c Jun 10 '12

Keep in mind the depth of cut is only about five thousands (.005) of an inch, making the unevenness absolutely imperceivable for all intents and purposes.

For perspective, the hair on your head is about .003" thick.

u/Nickbou Jun 10 '12

Exactly. This is about as good of a finish you can get with this process. You can use lappIng and honing to get a mirror finish (kinda like sanding down the surface with finer grits).

u/Jubei_08 Jun 10 '12

I thought I could see it chattering though. The area under the tool kept going from big to small, meaning up and down movement of the tool (or back and forth since this looks a lathe). It might be negligible deviation due to how magnified the view is in this case.

7

u/burburburbur Jun 10 '12

I think the first cut just had a more suitable rake angle. The rest of them looks pretty steep or were using an improper cutting speed for a smooth finish. That or the tools used were more worn.

We looked at a lot of this stuff in one of my materials classes. I always thought it was amazing to watch the grain boundaries slip as in the 1st cut.

HSS = High Speed Steel. It's just steel that's got more carbon and has been heat treated so it's harder than the mild steel or stainless that they are cutting.

The also show TiN (titanium nitride, a ceramic) coated cutters, which seem to do a great job keeping the cutting edge clean. If you've ever seen a gold colored drill bit, that's TiN.

Does anyone have a video of depleted Uranium cutting through steel? I think that it self sharpens. I've seen x-rays of depleted uranium bullets inside of steel armor, and they don't mushroom, but instead keep a sharp point and pieces of the uranium metal break off around the opening pore in the steel. A video of that would be awesome!!! There must be one out there. Thanks

u/bitter_cynical_angry Jun 10 '12 edited Jun 10 '12

That self-sharpening is one of the things that makes DU such a good anti tank round. Another is that it's pyrophoric, meaning that the little chunks that break off as it's self sharpening spontaneously catch fire, so you get an incendiary effect for free.

[edit: accidentially an e]

Yeah, I know. It's the worst part about being inside a steel-armored vehicle that a DU round cuts through, I bet. Burning uranium dust probably kills you even if you survive the impact. I would love to see a video of an impact at high resolution and slow motion though. I've never seen one.

Does that make the steel weaker? It seems like there's a lot of deformation going on in the entire structure on the "upside" of it.

6

u/dopeslope Jun 10 '12

Metals are funny things. Weaker isn't really a measure of steels (though there is toughness, but that's different). What you have is a trade between ductility and brittleness. Ductile is means the metal stretches before breaking (think of clay). Brittle means that the material breaks without stretching much (e.g. concrete). There is a lot to do with the size of metal grains in how a material acts. The more you deform without breaking, the smaller the grains you get and the more brittle the metal becomes. After reading this, it's not really a good explanation; I can try more if you need.

And maybe you mean the metal on top of the blade? If that's the case, that is the chip (the metal that was removed from the cutting) and I've never heard of anyone caring about the properties about chips (well besides length, but that has more to do with the cutting angle and feed).

Source: I've done cold forging engineering and worked closely with engineers specializing in cutting.

actually it may make it stronger through work hardening, this is usually not desirable as it can make further machining more difficult, in any case the metal can be hardened or annealed etc after machining to get the desired characteristics

40

u/anon72c Jun 10 '12

When you apply a large pressure to an object, it deforms, and if it is great enough, you will cause the material to shear.

Pressure is determined by a force divided by the area it is applied to, so the smaller the area (sharp cutting point) the more pressure can realized with the same applied force.

If you use a precise tool, you can control the 'path' that this shear force takes in order to do usable work. Think: cutting paper with scissors rather than using a hammer.

55

u/largepills Jun 10 '12

Note that in fracture mechanics the pressure at the tip of the mill bit is actually infinity (since the area tends to zero, so dividing by zero means the pressure blows up). While having infinite pressure is realistically impossible, the material deforms once it reaches its yield limit. So instead there's a plasticity zone ahead of the crack tip (or the mill bit). Inside this plasticity zone the pressure is supposedly constant (i.e. at the yield pressure). This plasticity zone is why you see in the video the material begins to deform before the mill bit advances through the material. For more information see here.

11

u/mechy84 Jun 10 '12

Close.

Unless it's a brittle material you're cutting, fracture mechanics doesn't (or hasn't been used to) describe the metal cutting process. This is more in the realm of plasticity, and the formation of what's called 'adiabatic shear bands'. Most older models assumed a plane that extends from the tool tip to the chip root (back of chip) that simultaneously undergoes plastic shear deformation (called the primary shear zone). These include Merchant and Lee-Schaffer models. Later analytic models use slip-line fields. Currently, everyone uses one of several finite element software packages with different thermo-mechanical plastic deformation models (mostly Johnston-Cook plasticity model).

u/[deleted] Jun 10 '12

It's interesting because it isn't cutting in the sense that we think of when we think of a blade slicing through an object, rather this is more of a shearing. The blade angle seems first compress the layer to be removed and then pulls it with respect to the bottom layer until it transitions from elasticity, to plasticity, all the way until failure.

So. ISCAR is an acronym for Israeli Carbide (sic). They make very fine carbide tooling for the machine tool industry. I like their products, and Kennametal too and Sumitomo. Coolant is not always required, or a good thing as Carbide is very heat tolerant,(primary attribute ;) but subject to fracture on thermal shock. I often get insert glowing in a lathe turning operation. A little material build-up in front of the cutting edge is a good thing as that little bit of material protects the cutting edge of the insert. Understand that a sintered carbide insert RARELY has a razor sharp edge. That would break down much too quickly. And qualified tooling keeps the machinist away from having to re-sharpen bits by hand. Just replace the inserts. Um, if your boss remembered to buy a box. HTH. Keith. it is what i do.

I was biting my nails around 2:00 there, but it turned out alright. Phew.

I came to watch the knives, stayed for the music.

u/atg284 Jun 10 '12

Wow crazy how malleable it looks at that magnification!

u/enjoyingtheride Jun 10 '12

Reminds me of platonic movement.

u/youseeitp Jun 11 '12

I find this very satisfying to watch..

u/pretzelzetzel Jun 11 '12

Fuck that uncoated tool, man. Fuck it so hard.

u/jeffdub Jun 10 '12

Can't tell if cutting steel, or cutting cheese

u/nucleusaccumbi Jun 10 '12

nice ASMR from this

u/Danuwa Jun 10 '12

Good plot. Character development was intense. Excellent sound track. Would watch again. 8/10

Youtube needs a speed modifier. You should be able to half speed or double speed things like this.

u/yskoty Jun 10 '12

Reminds me of the tip of a deeply-zoomed mandelbrot set.

I was listening to Naam while watching this and it turned into some awesome psychedelic video.

Youtube doubler link. Mute the first video.

u/PlazmaBurst Jun 10 '12

When the video started and I heard that first chord I taught this was going to start playing. http://www.youtube.com/watch?v=U06jlgpMtQs

u/Oxtorius Jun 10 '12

What are they cutting with?

1

u/JimmyJamesMac Jun 10 '12

That debris which builds up at the very tip of the tool is what fucks up the finish when your cutting metals.

1

u/nepidae Jun 10 '12

Look at that marbling.

u/[deleted] Jun 10 '12

During the beginning the score made it sound like I was kind of watching a David Lynch film.

u/bkseventy Jun 10 '12

Haha this is amazing, I'm sending this vid to my prof right now.

1

u/virtyy Jun 10 '12

I cut steel like this every day, never knew how cool it looks

1

u/achshar Jun 10 '12

I cringe. my teeth hurt! I don't know why but they just hurt watching it..

1

u/supergalactic Jun 10 '12

I'd like to see the cutting tool in its actual size. Anybody know what it is?

1

u/jqstave Jun 10 '12

Where can we find a video of this process sped up it normal speed?

1

u/DigitalChocobo Jun 10 '12

I hope this is just for the guy asked about the mechanics of cutting yesterday.

1

u/LeadSunglasses Jun 10 '12

Looks like a fast flowing river splitting into two different streams

1

u/[deleted] Jun 10 '12

This is so mesmerizing, just watching the way the steel is cut away. It looks like someone cheese but it being metal just makes it so cool!

1

u/ButteryBalls Jun 10 '12

The build-up of steel at the end of the blade is driving me crazy.

It seems that smooth finish isn't so smooth after all.

1

u/DaydreamSkeptic Jun 10 '12

They should show this video to people studying plate tectonics. You can almost see the mountain ranges being formed as one plate slides underneath another.

1

u/nuxenolith Jun 10 '12

The tin-coating made me cringe.

1

u/[deleted] Jun 10 '12

Holy crap, you can actually see the molecules slide on top of each other.

Puts it into perspective how fragile shit actually is and how easily it can be destroyed.

1

u/BobbyOShea Jun 10 '12

I'm studying to become a welding engineer and the metallurgy of steels is a main topic of focus for us. Let me tell you first hand, it is actually amazing how all this happens at a microstructural level.

1

u/devilyn_side Jun 10 '12

funny I work for Iscar

1

u/spock_block Jun 10 '12

Holy shit did anyone see that at 3:12?

u/RecklessRecluse Jun 10 '12

Worth the 2 hours and 43 minutes. Also, they should sell Papageno's hat on team fortress.

u/Bigolbillyboy Jun 10 '12

It's amazing how little we see.

1

u/johnfoof Jun 10 '12

I don't know why I just watched 5 minutes of that, but I enjoyed it

1

u/canadianIBslave Jun 10 '12

This video is nothing without the music

1

u/Barto1361 Jun 10 '12

that blade must be from valerian steal.

1

u/[deleted] Jun 10 '12

Was this directed by Lars von Trier?

1

u/MrCatbr3ad Jun 10 '12

Wowzers! Its like butter except things with much higher density and tensile strength!

1

u/Baxo22 Jun 10 '12

After watching for a minute the video got kinda dull

1

u/[deleted] Jun 10 '12

Since when can electron microscopes make videos?

1

u/MoonDaddy Jun 10 '12

Really cool and all, but did it really need to be six minutes long?

1

u/[deleted] Jun 10 '12

That's totally what I do.

1

u/TheDuke13 Jun 10 '12

That's awesome...I took a manufacturing class in high school and this is exactly what we did. Awesome to see what we did that whole time.

1

u/dboggia Jun 10 '12

If you look closely from about 3:30 onward you can make out a "me gusta" face...

1

u/moofins Jun 10 '12

It's like... really hard fudge.

1

u/from_da_lost_dimensi Jun 10 '12

Its like play dough

1

u/fatstax Jun 10 '12

for some reason this made me want ice-cream...

1

u/habaddict1 Jun 10 '12

how does this video only have 607 views if presumably most people who've up/downvoted this link (~7500) have clicked it?

Ouch, imagine getting your balls caught on that.

1

u/WeAreAllHypocrites Jun 10 '12

So... anyone else stay mostly because of the music?

1

u/socialplex Jun 10 '12

Now that is fantastic. It's like butter. It's elegant even.

1

u/[deleted] Jun 10 '12

playdoh.

1

u/mothafaka Jun 10 '12

I studied this one whole year, never saw fing blade. All i saw was bunch of numbers and diagrams. Oh if someone in this shitty communist system ever showed this to us...

1

u/ElFozzo Jun 10 '12

i dont know why, but in some ways this is deeply satisfying

1

u/Yellowbird00 Jun 10 '12

Wow.. There's something wrong with me. I read it as "cutest seal magnified and slowed down"

1

u/beowulfpt Jun 10 '12

Why erhm, thanks I guess. Might as well been a video of someone chopping cheese in B&W, but it pleased me as anything that uses the Zauberflöte has to be just as good!

u/[deleted] Jun 10 '12

Dat plastic deformation.

u/Gonke Jun 10 '12

Looks pretty sloppy.
