Cutting tool & metal chip formation video

Amazing slow-motion videomicrography (loud -- turn the volume down):

I'm surprised by how much material build-up and fracturing occurs at the leading edge of the bit. It's a wonder that it's even possible to get a smooth finish.

    OK, I watched the whole thing. The large deposits of material build up that are left in the wake are interesting. They look like boulder. We're there any measurements to give a sense of scale?

    Must be a slow Sunday night if I'm watching metal chips.

    Interesting stuff. It could easily be cream cheese, peanut butter, or plate tectonics.

    I would have never imagined the process to look like that. It was kind of interesting to see an occassional amount of metal go under the bit, instead of above it, which must obviously be a direct result of tolerances built into the cutting machine.

    If you look at the video starting at 4:07 You'll see the chip material has stopped moving and its bunching up in front of the tool bit.This is not good.

    I'd attribute the occasional amount of metal going under the tool bit to human error. Too much speed and too much feed. Not to mention the lack of cutting fluid.
