How Metal Cuts

[Former Member]

I see all sorts of posting on what we perceive materials do when being cut, well here it is under an electron microscope.

Really good video Degen. Those polished aluminium cutting inserts are pretty sharp but they look like butter knives bulldozing through mush at this scale. I saw a special vibrating knife on kickstarter which is supposed to cut more cleanly and easily. Anybody see anyone applying that to machining?

Vibration assisted machining (VAM) is a research topic. I found a paper on this with a broad survey of what people are working on. It is LONG paper. There are a lot of pictures showing many technical approaches for milling, turning, and drilling.

Vibration-assisted machining (VAM) is a process in which high-frequency small amplitude vibration is applied on tool or workpiece to improve cutting performance, especially for hard and brittle materials. It has been applied to several machining processes including drilling, turning, grinding...

.....just finish the pot of coffee, then hand feed, should be plenty of vibration...
Probably not helpful, but I got up too early for some reason today....
