I give up. What am I looking at? And why is it reversed?
ImAfraidYoureAllPsychosSoIMadeThisAccount
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?
Fletcher1985
Thanks!
ktheman
Maybe you don't know as much as you think you do... This is subtractive manufacturing because you're removing material.

Be cool substitute for wood chips. Or gravel at least.

What kind of machine is that? Looks similar to some that we have in our shop.

Make sure you run M4 in stead of M3 when doing additive milling.

We had a graphics design company's artists machines too. Your dream may have included fairly sluggish gameplay, or smaller maps.

Can confirm as a welder mild steel can be brittle blue or a vibrant purple depending on temp went cooled/at the time

bluegas68
Heat.
BlackDeku
Because it's an ultra-rare item.
hiro300
Heat makes an oxide layer on the steel. The color is from the oxide thickness. Just like soap bubbles.
barrettsmithbb
It's from the temperature, purple is around 500F.
MapedMod
Oxidation caused by heat.
3Rsim
They are between 271-283°c. Friction makes shit hot.

I thought they were crocus petals. Nothing wrong with thinking it's cabbage- cabbage is good for you :)

At least you’ve got an eye for veggies. Not as fat assed-ness, could be worse.
originalBabewiththePower
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.
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.
RyBorgington
Depends on the material but tan is the optimum color for most steel machining
THUB
This is too little space for me to put all the reasons I disagree with that statement. As a 12 year machinist.
basiecally
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.
THUB
That's definitely true, especially because blue and the dark grey color steel goes at the end of the spectrum are close visually.
aenge
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.
MegatonSTL
So, what endmill, spindle speed, and feedrate are you using?
DaFuqisnull
I'm in an apprenticeship for Machining. You like what you do?
vegivamp
... i didn't really watch the tool, and thought this was red cabbage being sliced... I am not a smart man.
Krembananen
Good answer! Cool video aswell :) Former CNC Operator here.
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
HellooooNurse
You had me going for exactly 2 seconds op. Good shit
tocfanke4
Brohamma
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.
Vaeevictiss
I always got purple shavings when there end mill started getting dull. Didn't know this was intended.
Krembananen
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
Krembananen
Change colour. Sometimes air cooling is needed, other times emulsion coolant is needed. It all depends on multiple factors.
Vaeevictiss
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
idontfitin
so heat turns it purple? cool. does it stay purple or turns grey/silver when cool?
hiro300
No.
Recreationaldrugsnuggler
Im assuming an oxidation type reaction, which would be permanent unless you remove the oxidized layer, like sanding off rust
AnonOmis1000
Tgeres actually a decent range of comers you can achieve. It starts st a golden straw, slowly becoming light, then dark blue, then purple.
Milesgloriosus
Heat helps form an oxide on the newly exposed metal, that oxide is different colors based on temperature. Same as on exhaust pipes. Sorta.

Stays. Fun thing, you can use it to distinguish how hot it was: https://de.wikipedia.org/wiki/Anlauffarbe (couldn't find English source)

Found it: https://en.wikipedia.org/wiki/Tempering_(metallurgy)#Tempering_colors
Hammerwell
It's in the Tempering article: https://en.wikipedia.org/wiki/Tempering_%28metallurgy%29#Tempering_colors
dvd587
So what’s actually happening is an effect called thin film interference. The metal gets hot enough to accelerate the oxidation 1/8
dvd587
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
dvd587
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
aenge
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.
NoEyeDontKnow
What material is being milled? Looks like Ti
aenge
H-13 tool steel
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.
aenge
Heat goes to the chip, not the part. If done improperly then yes, it would warp the part
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
iPickedScout
Tempering is a slow heating process to make metal less hard and brittle, this is not what's happening here.
soniclettuce
Tempering reduces hardness to improve durability. Things that are too hard are brittle and would break easily.
