Today we are machining some metal inside the scanning electron microscope! By creating a custom fixture, we can manually advance a carbide cutter and cut metal inside the vacuum chamber of my SEM. Then we can construct a timelapse of those images to see what metal looks like under extreme magnification when being cut!

Wow. It's much less crystalline than I imagined. More like moving that clay you demonstrated on. Interesting how it pushes until the stress builds and then separates.

@TheLtVoss 11 месяцев назад

Well aluminum and it alloys are known too be very ductile aka "gummy" steel would be a way better demonstrate for the cristals and well there size depends on the heat treatment and alloy

@@TheLtVoss Isn't mild steel more ductile than 6061? If I'm remembering the young's modulus graph I think mild steel goes from elastic to plastic later than 6061. But, I'd have to look to be sure. Copper is, counterintuitively, stronger than steel or AL. When we talk about material properties, we sometimes mix up the nomenclature in regular conversation.

You could install your own electrical feed through on your SEM chamber. What would be really cool is if you could cut some steel that you first etch to display the grains and then show how the grains under the cut are modified by the cutting process.

@charleslambert3368 11 месяцев назад

@MrFaaaaaaaaaaaaaaaaa 11 месяцев назад

I am glad mr breaking taps decided to give the ol' elbow grease method a shot before drilling holes in his shiny new electron microscope. There is also the method of placing some mechanism between the limit switches and the carriage that gets crashed into when zeroing out the carriage, and using the compressing force to do an iterative action (like rotating a knob 1 degree or w/e)

@Loebane 11 месяцев назад

My first thought was to use extremely high gearing and magnets on either side of the glass. Though maybe that would affect the beam...

I have also operated battery powered devices in vacuum... Best to seal the battery in its own "chamber" but some lithium batteries handle the vacuum ok, solid state batteries are best.

@BreakingTaps 11 месяцев назад

I've thought about it, but my machine (a little desktop SEM) does some internal gymnastics to move the chamber into position. So it'd be a bit more complicated than repurposing a flanged port or something 😢 Definitely agree about cutting some steel that has been pre-etched! Would love to see the grain boundaries moving around!

you could build a self contained electrical system. A sort of "anti-vacuum" chamber, where you could put a couple of batteries and an Arduino Nano, inside a sealed box entirely within the vacuum chamber. It could either have a bluetooth/wifi to let you advance it on command, or just be pre-programmed to move it once every 30 seconds or something.

If it's able to pull down to pressure in just 5 minutes, about his time per frame, it can't be that hard of a vacuum (can take hours for super deep vacuum levels).

@pauldavidson6321 11 месяцев назад

The cutting performance of the insert when running at speed is quite a lot different to the low speed shearing action you show in the stop action SEM sequence especially with negative inserts,they develop a stagnation zone with very high localized temps .

@shannow95 11 месяцев назад

Yes indeed normally at speed there's a sort of small liquid ball that forms just as the tip. There's this just right little window for cutting speed, too slow it cracks and ploughs like this video too fast and the liquid ball just melts the rest and sticks to the carbide tip

@joshyoung1440 5 месяцев назад

What does "stagnation zone" mean? Like where does the term come from? Is it a place where the blade essentially stops for a microsecond until the bit of metal in front of it melts and moves out of the way?

@@joshyoung1440 The blade. Never stops ,the material must flow over the raked cutting edge and become the chip or forced under the cutting edge and become the machined surface .the temperature at the stagnation point is 1200 deg C or higher depending on speeds,feed and materials, hope that helps

@Hydrazine1000 11 месяцев назад

As a materials scientist and engineneer, I absolutely love the close-up cutting action you've managed to capture! One word of caution though! And that word is "galling" or, if I use two words, "cold welding". Your stop-motion capture allowed oxygen to get in contact with all metal surfaces in between each capture. This has an unseen benefit of letting the newly created aluminium (aluminum) surface react with air to self-seal itself with a natural oxide layer. This alumina layer will act as a barrier between direct metal-to-metal unlubricated sliding contact and prevent galling. Once you do the cutting and image capturing in an _uninterrupted_ hard vacuum you'll have a much higher chance of two metal surfaces cold-welding to each other because no protective oxide layer can be formed that would reduce the chance of galling to occur.

@joshyoung1440 5 месяцев назад

@Hydrazine1000 5 месяцев назад

So cool thank you, very interesting how the surface looks like it becomes fibrous when it curls on itself

The best part is at the microscopic level, it shows that although we see it as a perfectly smooth surface, it's actually riddled with imperfections.

I'm watching this video again and again.... thanks so much for spending all that time making it... your efforts are certainly appreciated here.

I love the stop-motion. I love the idea of a clockwork mech. So cool!

I appreciate that you synced the frame changes to the background music. Still love and await your videos! Stay awesome

This is So great! I am a self taught machinist, with a background in woodworking and I've found it hard to build a mental model of what goes on at the tool edge cutting metal - thinking of the metal as fluid, being pushed is really helpful as a way to get away from my mental model (and physical experience) of wood machining.

My dad was a welder by trade. But our cellar had a metal lathe, drill press and allsorts of machinist tools. But with my recent fascination with restoration channels, I have become fixated on metal working used in tool and equipment restoration. I wondered how one metal can cut another metal. I understood the concept of metal hardness, but this video illuminated the physical mechanics and science for me. THANK YOU!

love this one! I had a master's degree in metal cutting theory and made some stationary ESM photos myself almost 40 years ago.

I wish i had videos like this one when i was learning about the mechanics of materials, this video just made me understand things that i learned much better

As a hand engraver, this is absolutely stunning to see. Thank you.

Amazing work! Really didn't expect it to look as much like clay as it does.

This might be buried amongs the sea of comments but i personally appreciate the level of effor you go to into your work. Keep the good work dude.

It's cool they represented carving so well in surf's up, they used seashells and the shavings curled up the shell before rolling over exactly like it did in this footage, good video man. Also a great movie

I will definitely watch additional videos comparing cutter geometry and types of materials.

I'm a machinist by trade as well as a former professor. I appreciate the videos you create regarding the cause and effects of machining. These are great teaching aids both for the practitioners as well as the educators. Carry on Sir my opinion is you've found a niche in this world that is desired.

I've taken several undergrad materials science classes and spent hundreds of hours in the machine shop, and I never felt like I had as intuitive an understanding of cutting action as I do now after seeing a 30 second video clip. Absolutely wild, very very cool, thanks!
