It's a milling machine cutting a block of steel. If I had to venture a guess, it's a carbide end mill cutting maybe 4140 steel?

Well, there isn't really any purple junk food.
Hammertulski
Blue corn tortilla chips and black bean dip are kinda purple in the right light. That's still probably healthy, though.
Doopapotamus
Purple drank. Kids' cereal. Chicha. Grape-flavored fruit snacks.
Because if you do it right, all the heat goes Into the chip and not the part. I'm also using air blast which only cools the tool.

Called dry hobbing I think
thatlukejames
Hobbing is a process for cutting teeth or splines in stock. This is dry milling prob using carbide and air blast to keep the tooling cool.
ImakeEverythingAwkward
What material is that? My 24 hour machine work shop only let me cut 6061 Al land 1018 steel and none of them did that
vegivamp
... i didn't really watch the tool, and thought this was red cabbage being sliced... I am not a smart man.
Vaeevictiss
I always got purple shavings when there end mill started getting dull. Didn't know this was intended.
Depending on the material and the endmill used, you want to keep the temp within a certain margin. Sometimes that makes the chip 1/2
Change colour. Sometimes air cooling is needed, other times emulsion coolant is needed. It all depends on multiple factors.
Ya i usually only use cooling fluid with stainless. Never with aluminum as it never seems to need it. I only mess with it as a hobby as well
tocfanke4
so heat turns it purple? cool. does it stay purple or turns grey/silver when cool?
dvd587
So what’s actually happening is an effect called thin film interference. The metal gets hot enough to accelerate the oxidation 1/8
of the metal and thus starts depositing a very minuscule layer of that metal’s oxide on the surface of the chip. The reason why it gets 2/8
so hot is the cutter is designed in such a way to deposit most of the heat in the chip, thus preventing the cutter or stock material 3/8

Tgeres actually a decent range of comers you can achieve. It starts st a golden straw, slowly becoming light, then dark blue, then purple.

Heat helps form an oxide on the newly exposed metal, that oxide is different colors based on temperature. Same as on exhaust pipes. Sorta.

It stays that color, depending on the amount of heat it could be other colors as well.

Dude more those shavings are razor sharp. I used to clean mills and sliced my thumb so cleanly it didn't hurt a bit.
BobHubert
It’s due to tempering meaning these are very hard (not the only thing) this is something you look for when making a knife
soniclettuce
Tempering reduces hardness to improve durability. Things that are too hard are brittle and would break easily.
iPickedScout
Tempering is a slow heating process to make metal less hard and brittle, this is not what's happening here.
Tankynumnums
Correct me if I'm wrong but that's due to tempering the steel. Those shavings are about 540° F coming off of there. Does the part warp?
snipekill1997
Not tempering, the outer surface is hot enough that it gains an abnormally thick oxide layer that's exact thickness causes the color.
Heat goes to the chip, not the part. If done improperly then yes, it would warp the part
NoEyeDontKnow
What material is being milled? Looks like Ti
H-13 tool steel
basiecally
It’s just really unusual to see purple chips in steel, they often come out a shade of blue. Purple is a very tight spectrum of temperatures.
miner1coalminer
Thank you!
halosk8ingking
Feed rate is a bit too high
THUB
Kind of, but steel goes from yellow to red through to blue at a predictable temperature, so if you've got the cutting speed right, purple.
Yeah, it’s all predictable based on temp and alloy, but from my own work, dark and light blue seems to cover a larger spectrum of temps.
That's definitely true, especially because blue and the dark grey color steel goes at the end of the spectrum are close visually.
RyBorgington
Depends on the material but tan is the optimum color for most steel machining
This is too little space for me to put all the reasons I disagree with that statement. As a 12 year machinist.
