    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.

    It's crazy to see how much the metal behaves just like clay. There is a lot of aluminum in normal pottery clay, so it kind of makes sense. There is a ton of silicon too. Aluminum is a lot more malleable than people realize. Another cool thing that would be similar, is how sandpaper works with an electron microscope. It would be similar, but more chaotic. That video was well worth the hours you spent on this!

  • @user-tc2ky6fg2o
    @user-tc2ky6fg2o 5 місяців тому

    As one who worked with both machine tools, actually cutting metal, and worked in a carbide cutting tool factory as a grinding machine operator, I have to say this is the most fascinating view of the cutting process. We could watch it before via microscope, and high-speed camera only, not sure if the R&D had this view (but let's assume because they had a 3D diffraction machine to see the grain structure in the carbide).
    In the footage, it is clearly visible that the cutting edge is not "sharp". After we grinded it was much sharper. The edge itself is purposely rounded with an abrasive brush or sand-blaster, all computer-controlled, for a specific time, blasting from a specific angle with the specific sand type. All are customized to the carbide grade, and targeted material by the cutter.
    The actual cutting speed (the feed rate, the advance of the cutter) matters a lot in real-world applications, especially for certain cutter geometries and materials, it's a BIG + that it was reproducible in SEM at zero speed as well!
    The biggest part of the R&D of the carbide tools is towards productivity, the higher removal rate of the material. Today's cutting speeds and feed rates are simply incomparable with the speeds from 30 years ago. In some applications, you just see (or hear) a jet of chips impacting the inside wall or glass of the machine tool, while you only hardly can follow the tool movement along the toolpath.
    There are some videos on YT where in Indian/Pakistan workshop they use a lathe to machine a shaft. Sometimes they do it at a very low cutting speed, sometimes painfully slow. They use high-speed tool material, not carbide. But it works! The tool just has to shear the material as seen here. The achievable speed and productivity depend mainly on the tool material, geometry, material, machine tool, stability, and experience. The ideal conditions are tested in carbide factories and communicated in the catalog and on the packaging of the tool.
    It is clearly visible and explained in the video, that the tool does not "cut" or magically rip apart the atoms (or whatever we thought about the word "cutting"), but it pushes away the material and actually shears.
    If the edge is worn, the conditions change a lot, and the tool must shear a bigger cross-section or push toward the wrong (non-ideal) direction. It works for a while until you have to change the cutter.
    It works better to use worn tools in carbon steel, but in stainless, it is worse. The tool has to push away the material a little bit (plastic deformation) before shearing in any material, but the stainless steel however tends to work-hardening when deformed, i.e. a bigger section of material will be harder which wears the tool further (the tool is made for the non-work-hardened material, not the hardened parts)
    Many experienced therefore difficulties in cutting or drilling stainless steel. The tip from a factory expert is just to use sharp tools in stainless. If you have a roughing and fine pass, keep your roughing tool sharp, and then you will have no problem with the fine pass, easier to keep the tolerances with less wear on the fine cutter.
