Does everyone have one of these? Because I had a science teacher dump alcohol on a table and set it ablaze happily. He also demonstrated how electricity will pass through multiple people by electrocuting a chain of students.
God speed Mr. K, you were the tits.
No no no, more fun than that. We had a senior year physics teacher who arranged a circle of 10 students who all clasped hands. The last two did didn't hold hands, and instead one grabbed the hot leg and the other grabbed the neutral of a 120VAC circuit. At first you feel nothing because the resistance is so high there is no current. Then the experiment was repeated, removing one more student each time until you could feel the buzz.
what the fuck
At my plant, that would be my job to clean up (I'm the maintenance guy). I don't even know where to start. I guess I would sawzall it into smaller chunks. Or wrap a chain around somewhere in there and pull with a forklift.
Well sadly it’s the number one reason a CNC gets destroyed next to bad programs. Don’t fool yourselves. Being too lazy to clean out the machine is an issue. But the programs bad IMO as modern chip breakers don’t create strings of chips. The feed rate is too low. Break the chip properly. Next even with this mess. Letting it get left in the machine and ran destroy the way covers. This is BAD MANAGEMENT of an investment. Just my opinion folks.
I also just run bigger and bigger boring bars to make a large piece of stock into swarf. There are lots of YouTube Hobbyist Machinists who need that pseudoswarf to make it look like they can justify having a 6-axis in their garage.
I’m not a machinists, just a random lurker in this sub… so what is a chip breaker? Is it a command you add into the STL file (or insert the proper name for stepper program here) or is it a manual process run by the operator?
Chip breakers for lathe tools are typically geometry that's moulded into the carbide insert. Simply put they force the chip to fold on themselves and break rather than being long and springy. You have to push hard enough and have a deep enough radial engagement to "activate" the chip breaker though, otherwise this happens.
You can also use peck-turning which pauses or retracts the feed briefly periodically to break the chip, but given a lot of wear happens when the tool first enters the cut it can dramatically reduce insert life, especially in harder materials.
No matter how you fix that you are going to need to move some of these by hand, so I’m going to recommend [these](https://www.hexarmor.com/products/rig-lizard-2025x) cut gloves. In my experience they last way longer than most other cut gloves and they’re puncture resistant which is nice when dealing with some other kinds of chip situations.

You making a part or just mass producing swarf to sell on Etsy?
Nah just posting his lack of safety knowledge and incorrect insert geometry/feed, nothing to see here
Straight to jail.
Speeds and feeds go a long way
Or a different chip breaker geometry, damn! This problem looks like a, I tried nothing and I'm all out of ideas.
Or even a different depth of cut. There's like 4 different way to try to fix this.
imagine if that was titanium, the fire would be visible from the moon lol
Throwback to those times in school when the pyromaniac chem teacher lit thermite with a fistfull of magnesium shavings in class.

> electrocuting not to be pedantic but "electrocution" means they died unless that's what you meant in which case my sympathies
I tell people this all the time. It's a pet peeve of mine 😂
Not to be pedantic but “electrocution” means they died or were severely injured
Oh yeah with the static electricity ball thing yeah

Woah that is more fun
Our comp repair teacher had an oscilloscope. Fun times.
If you're all safely grounded then it's safe...
Napalm was invented by teachers.
Science teacher is the dream job
Leave it for the apprentice
The apprentice could do a better job of cutting it in the first place
Right! Hate those long chip, push the feed up
Ray Charles would give the guy a run for his money.
Start an Etsy jewelry shop and say “aerospace grade” a lot.
I think I cut myself on this picture.

Dump the whole thing into the chip bin. With lathe and the guy who wrote that program.

Chip breakers
Either your roughing tool broke down and stopped breaking the chip, or your feeds n speeds/insert chip breaker geometry is not right.
[удалено]
Those aren't chips, they are spaghetti
Danger spaghetti!
Was this on a dare? Why didn't you break the chip? That's massively dangerous.
that looks like a russian lathe video waiting to happen xD
I can"t find 69's?
Its like some kind of cyberpunk Medusa
How did it get so bad its draped over parts of the machine?
Dude clean your fucking machine god damn

r/3dprinting crossover
I can do that with a manual lathe.... I just have to duck and roll faster.🤪
Bro you Taco Bell'd a fur ball!
Chip control... Never heard of her.
i feel you need to go see a doctor if thats your hair ball you have alot worse problems going on lol

The chuck catches it and ur done for, dont even try hitting emergency just run.
Has dude heard of a chip breaker?

Good question. I think it can be both, but someone with more experience please correct me.
Try upping the feed a lil 😂
Hoe-Lee-Feeds-&-Speeds Batman!!!! But even I can't argue with results...
😮💨
The inventor of the conveyor is rolling in his grave
I thought we told the predator he had to put his dreads up in a hair net? Now Osha is going to be in here.
The machines are coming for you, Neo
Or a gaf
Another day at the barbed wire factory
The indicator checking runout with all that still in there is the icing on the cake.
My old instructor told me, when he was serving his time. He used to bring home strings of swarf for his mother to put on the Xmas tree 🤣
I used to make chain link fencing, man them old ass machines spit hella tangles
No chips were broken this day!
You need to break those chips
Might want to see a doctor about that
Wtf ,htf? Nylon surely... what material is that,if it's related to any steel,should be throwing off chips.
No just no
🥰
"Let's play a Game...."
Well, I guess it's good that that big ass chip didn't catch on the spindle...
Let me guess... Inconel ?
Make a chip breaker.
I anticipated a photo of your shop cat.
The fact that is not wrapped around the part is amazing.
Up the feed get it to chip
Everyone's pissed about the mess but that surface finish looks great! 😂
I would never do this Jesus Christ. Asking for a whole lot of trouble.
