I thought this might interest some people in here.

chip formation analysis is a fascinating and useful science.

actually such research has lead to me to often thought experiment about the notion of super sonic machining. ie, machining a material faster than its compression wave propagates, and thus, you would see none of the inherent negatives associated with plastic deformation of the material. rough calculations i have done makes such a cutting tool pretty insane, ie 1m cutting radius, 300krpm+ type stuff.
need a couple million dollars to build a prototype, but i imagine if it could be done, one could cut with surface finishes better than polished or ground surfaces. assuming of course your machines error motion was on the order of ~100nm or so.
.... all in a days work ....

Only slightly related; since it applies to things being made.

The reason I ask is that I have a Phantom (Miro LC320S with the PL mount for when Morolen comes along) coming in my direction once they clear their backlog and potential work is always an opportunity to play with lenses and different setups
I love videos like this.
It's fascinating because I have made all kinds of chips, and then watching the video you get to see what caused a chip to be a certain size or shape. Very cool!
Not that I have ever known. Toolmakers like to show the videos of their tools cutting though.
well that depends. most do not. some do.
cutting science, in order to maximize material removal rate is key in several industries, such as aerospace. where making large titanium pieces with massive cut times (like 30+ hours) is fairly normal. here, even a 5% increase in material removal rate saves tens of thousands of dollars. so figureing out ways to remove the most amount of material per unit time is key.
i won't go into specifics cause its touching a bit too close to what i do, but yes, companies, the government, lots of folks are interested in understanding the mechanics of cutting and chip formation to improve surface finish, form error, and productivity. these arn't your 5 haas CNC machines on an industrial flat down the street companies no. Lawrence Livermore, Oak Ridge, 3M, Dow, big boys doing fundamental scientific research ... these kind of guys are interested in this stuff.
