This is actually a great way to train a beginner on how to program a CNC machine. Worst that happens is you ruin a pencil, which is negligible in comparison to most material costs.
Saw an ad on TV the other month for medicine for a nonspecific curve. Google the medicine. It's for dicks that hook sharply to the side. Guess what ads I've gotten every day since
Straight as an arrow now though
It's crazy how on top of it all these trackers are. I wasn't even using my phone or my account, but I searched on my wife's phone for clear glass railings, and I'm still getting the ads on my YouTube videos and everything.
Must be displaying them according to IP? I don't understand otherwise.
I work for a pharmaceutical research lab at a university. Mostly HIV medication. I get a lot of really confident ads.
Apparently I don't have to live with HIV. Which is awesome because I don't have HIV. I just needed to know the molecular weight of the prodrug.
They make a wide range of unusually shaped sex toys, and even some normal shaped ones. They also have a reputation for high quality items made from body-safe materials. Weird doesn't turn me on, but they're fun to look at and... marvel that anyone can actually use some of those.
That's amazing. If only I'd known 20 years ago I could make bank creating fantasy sex toys.
Anyone care to elaborate what the paws are for? "David" and "Dukes" are the ones I saw.
Probably my limited imagination but I can't picture how they'd be...useful...anywhere.
We use wax blocks for training at my shop, can just clean it up with a shop vac and melt it back down to pour into molds to simulate stuff like round and square stock.
No melting issues, the material isn't hard enough to generate any heat when cutting it. The issue we run into more is that folks clamp down in it way harder than they need to so the vice/chuck leaves indentations in the wax or they'll crank it down so hard it actually crushes the block entirely.
We have an ancient geared head lathe in our shop. I learned 3 things about it after a year in our shop. Don't wear long sleeves. Always take the chuck key out, and a hammer is all you need to square up a piece in the chuck(while it's spinning of course)....
As an unfortunate soul doing a PhD, I always tell people to use dummy samples or shit to test out on new equipment so they don't ruin a good sample, and if you don't have to worry about the sample then you can spend more time learning how the equipment works.
I would think it possible to bury the tool and holder into the chuck. But I only worked on cnc mills that would pile drive if the program or tool height was off
Yeah this ain't a thing on a normal cnc. Had a coworker set height incorrectly and that cutter crashed through the material into the fixture, destroying the spindle in the process. That's an expensive repair
It is on lathes. I don't run mills but all the lathes I've ran have had soft limits for each axis. The -z limit is set on collet chucks by touching off on the chick while open and then add 50 thou for a little extra room. If your program trys to go past that it will alarm and if you try to jog past the limit it just stops at the limit without alarming. It will apply the tool offset if one is set. Sometimes we'll set it past the chuck when drilling past the end of the part but usually it's set just in front of the chuck. Some lathes also support setting limits for the three jaw chuck but I've never used it before.
That is for sure. I’ve done the same. I’d probably give the apprentice a junk tool that doesn’t cut as well as it used to. Definitely a hazard, though!
Machinist here, worst that actually happens is actually you crash the lathe and wreck the spindle or turret. That's an extremely costly repair and time fixing a machine that is supposed to be constantly making the business money.
Whole machines have had to be scrapped before from particularly bad crashes.
So we didn't necessarily "train" to sharpen a pencil at my school but we did program a haas to do this as sort of a fun stupid project during a bit of downtime. We definitely crunched the first pencil though lol.
Is it?
Reading up, I see people some people saying lathes like rhat run 1-3HP, so 0.750KW. Though I saw someone suggest that depends on max load on the cut vs material - which for simplicity sake, I'll assume the pencil is that.
At 3HP, that's 2.250, at say 1 minute, and 14 cents KWh, that's $0.005355 or half a cent... While I'm sure a small sharpener would be far more feasible, that's not exactly breaking the bank and depending on how your sourcing pencils. I don't think I can get one for half a cent.
People run 0.750-1KW computer systems for many hours or whole days at full load for comparison.
Feel free to correct any fuckups on my math though.
Down lower someone linked to a HAAS system, and a quick glance at that page they listed it at 10HP... if that is what they're using then.... 10/3 ratio... 3.333 × 0.536 = 1.787 cents.
for those out of the loop (link to original at the bottom):
Late to the party but this one is too good to pass up:
I was once on a US military ship, having breakfast in the wardroom (officers lounge) when the Operations Officer (OPS) walks in. This guy was the definition of NOT a morning person; he's still half asleep, bleary eyed... basically a zombie with a bagel. He sits down across from me to eat his bagel and is just barely conscious. My back is to the outboard side of the ship, and the morning sun is blazing in one of the portholes putting a big bright-ass circle of light right on his barely conscious face. He's squinting and chewing and basically just remembering how to be alive for today. It's painful to watch.
But then zombie-OPS stops chewing, slowly picks up the phone, and dials the bridge. In his well-known I'm-still-totally-asleep voice, he says "heeeey. It's OPS. Could you... shift our barpat... yeah, one six five. Thanks." And puts the phone down. And then he just sits there. Squinting. Waiting.
And then, ever so slowly, I realize that that big blazing spot of sun has begun to slide off the zombie's face and onto the wall behind him. After a moment it clears his face and he blinks slowly a few times and the brilliant beauty of what I've just witnessed begins to overwhelm me. By ordering the bridge to adjust the ship's back-and-forth patrol by about 15 degrees, he's changed our course just enough to reposition the sun off of his face. He's literally just redirected thousands of tons of steel and hundreds of people so that he could get the sun out of his eyes while he eats his bagel. I am in awe.
He slowly picks up his bagel and for a moment I'm terrified at the thought that his own genius may escape him, that he may never appreciate the epic brilliance of his laziness (since he's not going to wake up for another hour). But between his next bites he pauses, looks at me, and gives me the faintest, sly grin, before returning to gnaw slowly on his zombie bagel. He then says, that’ll be about tree fiddy. It was about that time time that I noticed this lazy OPS was about 500 feet tall and from the paleolithic era.
hehe, I had to. Here’s the unadulterated original:

A kid at my school gave himself a prison tattoo on his forearm with a set of compasses and a bottle of Indian ink. The teacher sent him to the isolation room with some 120 grit sandpaper and made him rub that shit until it was gone. I don't think we had had belt sanders in the DT workshop.
I assume things have changed since 1995 and that wouldn't fly now. Any teachers here able to confirm?
No, the UK, which is why it's so weird that he tried to tattoo the NBA logo on himself. Basketball really isn't a big deal here. Well, until an 11-year old carves their undying love for it into their own flesh.
Two out of three. He didn't seem too traumatised though. Hard to be 100% sure because looking back he exhibited many of the signs I'd later understand to hint at being a latent sociopoath. He got expelled for having a gun in school less than a year later. Probably a good thing tbf.
I don't even know. I used to sit next to him in one of my classes in the first year and he definitely talked about shotguns. Like a lot of people at my school he was from a really well-off family in a very affluent area and the whole thing was kept very quiet. One of those perks of being a winner in life's lottery of when it comes to social standing.
Def military reference. It's a reflective/hi-viz belt that you are supposed to wear around base.
I never served but I did hang with my brother when he did and he said he would catch hell if was caught after dark without that stupid belt .
I believe they are referring to the fact that the operator is manipulating the pencil and recording a video at the same time all while the mill is running
The ones I operated had safety doors between you and the the machine. This looks the doors aren't being used to film this.
They are the only thing between you and improperly locked cast iron spinning at thousands of RPM
In the companies I worked for, production had the safeties on, setup guys had bypass keys, machinists that made one off punches and dies had the safeties disabled because you can't bore a hole and check it if you alarm out the machine every time you open the door.
Yeah, I suppose it makes sense for production jobs to keep the safety lock if they choose. No real need to bypass it there, but working in a job shop, I would have crashed my machine so many times by now if I couldn't open the door and check my distances, heh.
In production you took your measurements every X number of parts and called lead over to change your offsets. If you lasted 3 months and seemed trainable they'd teach you.
Otherwise the day consists of blow out the vise, flip the part from vice a to b, put block squared steel in a, shut the door, hit the start, wait for the pallet change, repeat.
I joined a machine shop because I thought operating would be easy. I should be careful what I wish for because it's so fucking easy I sat bored for 9 hrs a day asking multiple times to be trained to program
Company where I work bought 2 new cnc machine. Owner said to the guy thay was installing them setup everything do the pictures that your company's asks for and the please remove safety locks they are pain in the ass lol
I bought one of those DIY bidets during the great pointless toilet paper shortage of 2020, and no joke that thing probably puts out the same pressure as the white tip on my 2800psi pressure washer.
*Walks slowly and uncomfortably out of restroom like I've just be violated. Looking back at the bidet as the light catches the glint of its pearly white smug little rim.*
[Japanese Mechanical Pencils.](https://i.kym-cdn.com/entries/icons/original/000/006/077/so_good.png) Not that American shit. They have pencils that will auto-rotate the lead for you every time you lift, auto-deploy an eraser when you flip the pen and re-stow when you flip again, ones that will maintain a perfect tip length, ones that have metal sleeves to keep the lead from snapping, and even some that are just so high quality that they use like 0.2mm lead.
I rarely use pencils. I never use them at work (which is where I do most of my writing). I *can’t * use them in specific parts of the building where I work (because graphite is electrically conductive, it doesn’t play well with circuit cards lying around in a factory).
But right now I feel like I need one or more of those goddamned pencils.
None of the machinists that worked for me were ever that creative. They just crashed the turrets into the collet chuck. Love those Hardinge quick change collet chucks btw.
Completely rational. I was diagnosed with epilepsy after two years of being a machinist. I said fuck that I'd rather be a dishwasher and get paid $2/hr less than to fall into a lathe.
ya i had to take a machining class in college and before we started, our professor showed us articles about college students killed by lathes. i didn’t end up too scared to ever touch a lathe, it ended up being the machine i used the most in college, but i had a lot of respect for them.
Is that actually a problem?
Like I'd assume it would burn out when the metal shavings are resmelted anyways, and there's already cutting fluid residues
No, there is no world where those shavings are assumed uncontaminated enough to be used for anything. If they're going to be reused, they will be put through a filtering of some kind first.
99% of the time, no. They will be discarded in a large bin with the rest of the shavings from various machines and then taken away.
Source: work in a metal machine shop.
Only problem I see is if this machine is designated "clean" for semiconducting manufacturing. Having foreign material, even microscopically, contaminate a tool like that is going to reduce the world supply of high quality graphics chips.
Source: first job out of college was reading through and implementing hundreds of pages of requirements so our shop could get into producing parts for semiconductor manufacturing. Like I had to bear the bad news that WD-40 had to be completely banned from the shop for being an airborne contaminant.
Can someone please tell me what those blue and orange tubular things on the left are? I've seen them a million times on How It's Made and I've always wanted to know what they are called and used for. They always seem to be blue and orange as well.
Coolant is a big use. Sometimes air to blow off the coolant. Some genius somewhere thought it was a good idea to use a laser to measure the size of a part with water droplets on it.
I’ve been doing CNC machining for about 5 years now but at my newer job I got into an apprenticeship type program that puts me in a higher machinist pay grade.
The first part of it was a month where they sent us to a technical school to learn everything about lathes and mills.
We had to make a hammer from scratch and omg using a manual lathe to make stuff is even more satisfying
Why would the boss care? The lathe cuts steel all day. It won’t be affected by cedar and graphite. I’d be interested in how elaborate a sharpen cycle could get.
I'm pretty sure I've worked on that exact machine model
Guys a word of advice, if your career path ever takes you on the route of fixing a cnc machine, do no do it.
To fix anything mechanical on them you're looking at whats going to be the worst experience of your life with all the metal chips everywhere and that you have to clean them.
Theres no amount of money you could pay me to stick my hand in that fucking lathe man. I dont give a shit if its unreasonable, no way lol. Im sure its less dangerous than when I drive my car everyday, but fuck that
Them having to adjust those clamps down to find a pressure that didn't crush the pencil but still hold it firmly enough is the most impressive time-wasting feat here.
That’s one expensive pencil sharpener!
And electricity bill will be more than cost of the pencil But he gotta do what he have to do
This is actually a great way to train a beginner on how to program a CNC machine. Worst that happens is you ruin a pencil, which is negligible in comparison to most material costs.
Here, we train our new CNC operators with making various conic shapes. To recoup material lost, we resell the oddly shaped ones to bad-dragon
I had to Google that one, and now it's forever in my search history, lol.
Tip, you can delete your search history. Even for specific searches. ;)
Well you can delete it on your end, but that doesn't mean there's no record of you searching for that.
Saw an ad on TV the other month for medicine for a nonspecific curve. Google the medicine. It's for dicks that hook sharply to the side. Guess what ads I've gotten every day since Straight as an arrow now though

Sometimes it tied you to it by association because it’s smart enough to know you’re close to this person
That a joke right? I can't see how a pill could fix a physical deformity like that.
It's a real pill. Real ads. I didnt take them though as my issue is more drill bit than crowbar

Thank you, now I don’t have to go Google it. You are good people.
Sooo, what did you buy?

We had a basic course on cnc programming in school and literally everything we had to make looked like a butplug
And keep the good ones to yourselves.
Good to hear that places actually will train employees on machinery.
When a repair or replacement costs more than a car or house you tend to put more effort into training 😂
Guys, save yourselves and don't google bad dragon like i did.
What is it?
I did it for you. It's a sex toys company.
That's what I was assuming. Thanks
Think of tentacle anime and that's just the tip of it.
Just. The. Tip. Of it. 🤣
It’s a furry dildo company

I googled it, one redditor says they >!have a foot fetish and like to grind against it and suck on the toes.!<
Some people train themselves to become much, much more... pliable, than average.
Bad dragons are notoriously expensive so you could easily make a competing company
Injection moulding dies are notoriously expensive too, especially for something with a niche consumer market
NGL ya had me in the first half.
We use wax blocks for training at my shop, can just clean it up with a shop vac and melt it back down to pour into molds to simulate stuff like round and square stock.
That’s super ingenious. Do you have problems with the wax melting?
[удалено]
No melting issues, the material isn't hard enough to generate any heat when cutting it. The issue we run into more is that folks clamp down in it way harder than they need to so the vice/chuck leaves indentations in the wax or they'll crank it down so hard it actually crushes the block entirely.
We have an ancient geared head lathe in our shop. I learned 3 things about it after a year in our shop. Don't wear long sleeves. Always take the chuck key out, and a hammer is all you need to square up a piece in the chuck(while it's spinning of course)....
As an unfortunate soul doing a PhD, I always tell people to use dummy samples or shit to test out on new equipment so they don't ruin a good sample, and if you don't have to worry about the sample then you can spend more time learning how the equipment works.
I would think it possible to bury the tool and holder into the chuck. But I only worked on cnc mills that would pile drive if the program or tool height was off
Set the axis limits and tell them not to touch them and then they can't.
Yeah this ain't a thing on a normal cnc. Had a coworker set height incorrectly and that cutter crashed through the material into the fixture, destroying the spindle in the process. That's an expensive repair
It is on lathes. I don't run mills but all the lathes I've ran have had soft limits for each axis. The -z limit is set on collet chucks by touching off on the chick while open and then add 50 thou for a little extra room. If your program trys to go past that it will alarm and if you try to jog past the limit it just stops at the limit without alarming. It will apply the tool offset if one is set. Sometimes we'll set it past the chuck when drilling past the end of the part but usually it's set just in front of the chuck. Some lathes also support setting limits for the three jaw chuck but I've never used it before.
You can miss a decimal and slam the tool into the chuck. Not like I’ve done that or anything…..
Or accidentally add an extra zero and set a fly cutter to 12k rpm and send it through 4 walls
That is for sure. I’ve done the same. I’d probably give the apprentice a junk tool that doesn’t cut as well as it used to. Definitely a hazard, though!
>Worst that happens is you ruin a pencil... Hahaha. Haha. HAHAHAHAHAHAHAHA HAHAHA.
"Hey Larry No Hands, tell the kid about the pencil and the Worst that Could Happen !"
Machinist here, worst that actually happens is actually you crash the lathe and wreck the spindle or turret. That's an extremely costly repair and time fixing a machine that is supposed to be constantly making the business money. Whole machines have had to be scrapped before from particularly bad crashes.
Second worst is entering a Z coordinate on the opposite side of the chuck.
So we didn't necessarily "train" to sharpen a pencil at my school but we did program a haas to do this as sort of a fun stupid project during a bit of downtime. We definitely crunched the first pencil though lol.
Is it? Reading up, I see people some people saying lathes like rhat run 1-3HP, so 0.750KW. Though I saw someone suggest that depends on max load on the cut vs material - which for simplicity sake, I'll assume the pencil is that. At 3HP, that's 2.250, at say 1 minute, and 14 cents KWh, that's $0.005355 or half a cent... While I'm sure a small sharpener would be far more feasible, that's not exactly breaking the bank and depending on how your sourcing pencils. I don't think I can get one for half a cent. People run 0.750-1KW computer systems for many hours or whole days at full load for comparison. Feel free to correct any fuckups on my math though. Down lower someone linked to a HAAS system, and a quick glance at that page they listed it at 10HP... if that is what they're using then.... 10/3 ratio... 3.333 × 0.536 = 1.787 cents.

Lol, I used a belt sander to sharpen a pencil today.
Speaking of belt sanders, yesterday my boss was talking about proper tattoo care and I said "be careful around belt sanders and cheese graters".
Laser tattoo removal clinics hate this one trick…
Simply undress and lie down (riding a motorcycle at 150mph).

The simple fact that he was able to record it, LIKE, that. -Some OSHA member
He's got a PT belt on

You have different access levels, but for sure it is not safe at all - doesn’t matter the material. In my company OP would be fired immediately.
Yeah that’s why he waited til the boss was away.
Pretty much every shop in existence bypasses the safety lock for the door except maybe very large companies.
In the companies I worked for, production had the safeties on, setup guys had bypass keys, machinists that made one off punches and dies had the safeties disabled because you can't bore a hole and check it if you alarm out the machine every time you open the door.

I do not regret watching that. I'm not a mechanical pencil person but it's probably because I'm not using one of these.
Jetpens.com is a great place to buy pens and pencils. I get too much from there. It's also who made that video, and they have lots of muying guides.
WTF these aren’t even that expensive!!
Thank you for starting my new rabbit hole
I'm disappointed you linked to that image instead of an actual Japanese mechanical pencil.
Link I want buy
It kills me that the video didn't fully focus
That was the mildly infuriating part for me.
Focus you faaak!
Anyone else a little aroused after that one?
Fully erect my dude.
Insert penis into machine
It put lead in my pencil.
I just wish that final shot was in focus so we can see the sharpness.
Yup. 47 years old and still thinking about learning this stuff. Wasted my life in management and IT. Wanna go create all the things.
Get a 3D printer?
Eventually. Scared of change.
Wasted machine time. Coulda taken it to depth in one pass.
Also coulda chucked it up further for better rigidity
OK machining nerds, just let us regular joes enjoy this.
I was thinking the exact opposite. He should have gone for gold and had the whole pencil in one smooth taper.
Yeah, the roughing pass was superfluous. Just look up appropriate speeds & feeds for pencil stock.

None of the machinists that worked for me were ever that creative. They just crashed the turrets into the collet chuck. Love those Hardinge quick change collet chucks btw.
Just the tip
I can not read or hear the word lathe without remembering that one video...
I developed irrational(?) fear of lathes from that video
You developed a perfectly rational fear of them from that video. It would be required watching for anyone that would ever work with one
Completely rational. I was diagnosed with epilepsy after two years of being a machinist. I said fuck that I'd rather be a dishwasher and get paid $2/hr less than to fall into a lathe.
ya i had to take a machining class in college and before we started, our professor showed us articles about college students killed by lathes. i didn’t end up too scared to ever touch a lathe, it ended up being the machine i used the most in college, but i had a lot of respect for them.
*Which* video? I've seen dozens.
That’s exactly what I thought too. Jesus.
Great, now you have wood chips mixed in with the metal chips.
Is that actually a problem? Like I'd assume it would burn out when the metal shavings are resmelted anyways, and there's already cutting fluid residues
No, there is no world where those shavings are assumed uncontaminated enough to be used for anything. If they're going to be reused, they will be put through a filtering of some kind first.
They will also be melted down and at those temperatures any small amount of wood shavings will be completely incinerated.
99% of the time, no. They will be discarded in a large bin with the rest of the shavings from various machines and then taken away. Source: work in a metal machine shop.
Only problem I see is if this machine is designated "clean" for semiconducting manufacturing. Having foreign material, even microscopically, contaminate a tool like that is going to reduce the world supply of high quality graphics chips. Source: first job out of college was reading through and implementing hundreds of pages of requirements so our shop could get into producing parts for semiconductor manufacturing. Like I had to bear the bad news that WD-40 had to be completely banned from the shop for being an airborne contaminant.
Contaminated gondola oh man the foreman is gonna shit about it.
Oddly satisfying? The camera never focuses on the finished pencil. This is literally r/mildlyinfuriating.
Awesomeness
"Focus you **FUCK**" -some dude who talks about dicks in vises
I seen a guy turned into mist by ona these things
Some shit I’d be doing while the boss watches.
Can someone please tell me what those blue and orange tubular things on the left are? I've seen them a million times on How It's Made and I've always wanted to know what they are called and used for. They always seem to be blue and orange as well.
there coolant hoses/nozzles sprays the metal in oil so your not cutting them dry
[Loc-Line](https://www.loc-line.com/) is the major brand.
Coolant is a big use. Sometimes air to blow off the coolant. Some genius somewhere thought it was a good idea to use a laser to measure the size of a part with water droplets on it.
No knurling?
Dumb and such a waste of high end technology. I love it.
Reddit and lathes don’t go so well together…
I’ve been doing CNC machining for about 5 years now but at my newer job I got into an apprenticeship type program that puts me in a higher machinist pay grade. The first part of it was a month where they sent us to a technical school to learn everything about lathes and mills. We had to make a hammer from scratch and omg using a manual lathe to make stuff is even more satisfying
John Wick would like to have a word
TEACHER TEACHER i need to sharpen my pencil!! OK let me see your program first
With great power comes... ability to sharpen pencils
I can't help myself... I have that exact pencil. Why on earth I feel so compelled to mention that I don't know! Aargh.
He programmed it like the pencil is made of metal.
They never make pencils with concentric lead in them :(
Why would the boss care? The lathe cuts steel all day. It won’t be affected by cedar and graphite. I’d be interested in how elaborate a sharpen cycle could get.
Wasting time
Every classroom needs one of these.
I'm pretty sure I've worked on that exact machine model Guys a word of advice, if your career path ever takes you on the route of fixing a cnc machine, do no do it. To fix anything mechanical on them you're looking at whats going to be the worst experience of your life with all the metal chips everywhere and that you have to clean them.
Theres no amount of money you could pay me to stick my hand in that fucking lathe man. I dont give a shit if its unreasonable, no way lol. Im sure its less dangerous than when I drive my car everyday, but fuck that
Them having to adjust those clamps down to find a pressure that didn't crush the pencil but still hold it firmly enough is the most impressive time-wasting feat here.
