The only thing that could have made this better is a running tally of the cost of the parts, tooling, fixtures, etc. that were ruined.
Ain't nobody wanna do dat!! lol that would just be painful ;)
I thought this would be ecip. Like epic meal time :D
Would make me vomit lol
if anyone tallies it it'd probably John LOL
What ever happened to dry runs
Thank you for being so open about your mistakes, mishaps and experiences. It gives other people a chance to learn from it and possibly avoid similiar things in the future. Also shows us that everyone is human..........you wouldn't know that from reading a lot of comments on machining videos. They never make mistakes and were perfect at machining since the day they were born.
Great, now all the indian robot voice copycat channels can post new "CNC fail" videos without using the same five crashes over and over again.
John better watch out for those.
Right? You guys keep reporting those thief's! We'll keep crashing machines! I mean, granted, it takes us YEARS to get footage like this...
Years? How? I distinctly remember you saying you've never ever crashed a tool before...
There's a video on FB that's yours. I wanted to report it but FB provided no mechanism for doing so. Much annoyment.
@@JamesChurchill3 "that's my secret, Cap. I'm always crashing."
Damn there is so many videos like that, always the same title format containing lots of ‘hit’ words and sometimes don’t actually make sense “HYPNOTIC || CNC Machine Tool Work Heavy Fail Industry” with all these videos and never any credit given, and ofcourse a few ads in there to so they can benefit of other peoples content.
I feel like half of this video should be put in another video called "why work holding is the most important thing" lol
Also, there's some scary shit here...
Or titled why it's important to single block new programs.
Well single block for the first few cuts.
"Selecting the right feeds and speeds based on material and going easy on the cutting depth for dummies" by J. K. Machinisto is a nice book they should sometimes read
Also checking tool offsets. Like even eyeball it ffs
FlesHBoX and how too triple check before you make a cut😟
It feels so good to see that I am not the only one that crashes machines , snaps endmills... and makes scrap parts
Bernd Strauss I never scrap a part. I just make elaborate and unapproved engineering changes 🤣
I really appreciate your willingness to put your mistakes out there for all to see. We all screw up. The only way to improve is to accept responsibility and learn. Don't ever try to shift blame. A good boss will see right through that and you will only damage your own reputation. As a machinist, your integrity is everything.
Glad to see I’m not the only
One to end mill a parallel. Mine was a manual mill, but happened to be the FIRST use of a brand new carbide end mill. First one I ever bought.
I cringed in anticipation through the entire video.
I just kept saying "No... NOOOOOoooo" to each one. :(
Ive been in Cnc for about 20 years now , This brings back so many memories
Personally I'd like to see these types of things kept in the original videos as it gives more meaning and can provide a better lesson than a compilation video that has only entertainment value. And entertaining it was.
Agreed! I've seen a few videos in the past that made me think they were lucky to get away with a certain workholding setup etc. This compilation shows that in some of those cases they actually didn't!
Yeah; sort of like doubleboost does at the end of many of his videos: he adds a short clip of whatever bloopers he made during filming. It heightens the contrast between the finished video vs. the blooper.
Thank you so much! You made me feel so much better about my last few days screwups! I am at the end of a deadline and inam learning f360&cam as i go and i broke a cutter and felt so stupid! I saw that other people even pros do mistakes too. I found out something else- once you have only one cutter left and no time at all, you suddenly become very calm patient and careful :)
How can you tell this is an actual workshop you ask? Well the swearing ofcourse. No one says ''oh fudge'' after taking a huge bite out of their machinevise.
Nah its more like "OH BOLLOX!" 😂
1:40 possibly the smoothest save of the year 🍺😁🤘
what the hell was happening
A collet nut was singing us the song of its people.
People watching a machine crash. Pmsl.
There was nothing to safe 😂
came to say the same thing!
The most important part of innovation is the encouragement to make mistakes.
A swear jar would pay for all that broken carbide! Do you guys replace vise jaws with apprentice marks? I don't recall seeing any in any of the videos
I thinked the same
You'd have to pay quite a bit to keep my mouth shut after I broke a $100 tool or worse.
I'm guessing as fugal is John is they don't just throw them out, just not film with them.
You running to the machine to estop it as the other two were just staring at it was the best. Good save John
funny that endmills never seem to break when you try to mill your hard jaws
Fuck, I had a SGS 36513,( My now goto endmill for roughing in steel btw) in an er16 collet, a poor choice because i was pushing it hard enough for it to pull out.
Didn't even notice until it had slipped far enough to run out of flute length, that's the only reason it snapped. Left a beautiful finish 1/2" deep into my HRC60 jaws. Yes, That endmill is too awesome.
@@tomrevere9091 I think I was a few seconds of feed time from possibly dying when I was using a Bridgeport a few years ago. I was milling a 4x4 with the side of a maybe 3" flute length cutter, so I didn't have nearly enough tool in the collet. By the time I finished the cut, the tip of the tool was a good 1/2" lower.
My guess would be that those mills are HSS and not carbide
Scary stuff. I have thrown two parts in the last 8 months or so. One wrapped around the spindle and shot out the side window. I was really bummed out for a while. Thanks for sharing your mistakes!
LOL, the haimer at the end. Dying.
I felt its pain! :D
I pushed z- and fucked one!
One time put the measured value on the wrong box and crashed a 25mm drill, someone distracted me!
Great time!
Renishaw work probes. You're incredibly careful and may not break a probe for a year. But once you break the first one, you start breaking them like clockwork -_-
that shit pissed me off. theyre stupid expensive
@@ubbgn someone discracting me while im working is the most annyoing thing imo...
Dear God. I've never machined anything in my life, but that had to be the most painful video I've ever watched. I cringed so many times.
My kids put on horror movies every once in a while. I don't have any reaction to them. Turns out I'm horrified by watching tools get broken.
One of the things I really like about your channel is that you definitely show when things go wrong and, usually, what you learned to do differently. Love your work!
John, I have done EVERYONE of these and the only thing I am surprised at is the lack of swearing. At least you didn't mill your bed. One of my clients put a half inch gouge in their CNC table and their machine is big enough to fit your couch in.
something about end mills snapping is very enjoyable to watch. its like a weird satisfying feeling I can't understand. the haimer was great also. soo odd.
nice to see the mistakes, the internet give the impression that everything is easy mistake show us we are still learning.
Many channels give those that are trying new thing the impression they are failing when all they are doing is learning how not to do thing that fail
few show this step in the creation of things, it take strength to show our mistakes thanks for your show of strength
You just persuaded me to build enclosure for my g0704 cnc conversion.
I'm glad to see there are other humans out there making mistakes too love the bloopers👍
Thank you for uploading this video and injecting a bit of reality into this CNC thing.
This make me feel a lot better about the small handful of hiccups ive had in my first year. Yeah, no crash or thrown part is ever good but as long as you learn from it.
didnt enjoy it but was fun to watch my cnc heart is not going to sleep well tonight :o
It's good to see that everyone has a bad day. Thank you for the laughs!
Wow...you are only human. That makes me feel better for some weird reason. Great video🤪
Super honest of you! Great to see we’re all human 😀
mistakes are a sign of progress and experience.
"A master has failed more times than the novice has even tried"
You gotta learn through denial and error
I am brand new to CNC, so I don’t know exactly what it is I am watching, but what I do know is that this video is probably a great learning experience for us all. Thank you for sharing.
I enjoyed that, as a managing director of my own precision cnc factory , it's nice to see the true life of everyday machining. 😋
The surface grinder mistake at 1:14 could have been a hell of a lot worse. Breaking a grinder wheel while it is spinning is freaking scary.
Been there, done that - as an apprentice back in the late '70's.
One piece of the wheel embedded itself about 3/4 of an inch into a brick wall - after passing over my shoulder and travelling about 30 feet across a crowded apprentice cage!! I still have nightmares. ;)
We were told VERY early on in college to 1) NEVER grind aluminum on a wheel not meant for aluminum, and 2) NEVER grind steel on a wheel loaded with aluminum.
One of the auto mechanics in the shop next door probably wasn't paying attention, or wasn't told. And it's the only time in 12yrs I've heard of a bench grinding wheel exploding on startup.
@@thundercactus Why? What does that do?
The town I'm originally from has a long history in producing blades (knives, scissors, razors etc.). They used to use water mills by the river to drive huge (several tons) grinding stones. Well turns out, stones don't like thermal cycles a lot, so every now and then such a stone would explode killing everybody in the mill.
@@MonstertruckBadass well, a grind wheel not meant for aluminum will fill up with aluminum chunks and get clogged, after that it will not grind or cut anymore and just rub against your workpiece, and if you leave it alone and its set to grind a certain amount of stuff which it can't, the rotational energy on that bich is merciless
1:15 I did that exact thing, except on a Haas mini mill. Was running it manually just to some quick facing, thought I had enough clearance then ran the tool holder right into the clamp. Didn’t do much, just ground off a large chunk of the clamp, and put basically friction welded some of the steel from the clamp onto the holder
Here we see multiple reasons why these machines have shields and E-Stop buttons :D
Ours dont lol
@@FLUFF-lk4ww Not sure I'd want to operate anything without at least an E-Stop, but then again I don't do that sort of a thing for a living...
When you have 120m/min. in rapid-feed the E-stop button changes name to "Too late-button"
@@dietermeyer9231 well that's me enlightened then.
Thats only if you don't know what your doing!!!
My favorite part was John cursing.
My favorite part was when John said **bleep** **bleep** **bleeeeeeeeeeep**
Thats why machines with a feed rate override are so much better :)
Looooool👍👍👍👍
I've sometimes the same Problems with Grinding Tools.
Some Errors in G Code are Expensive
Wow, some of those crashes were a bit on the scary side. So glad no person was hurt. Thanks for the video.
Sometimes I get a little intimidated by how perfect everything seems to turn out when you make it. Its nice to see that you make mistakes as well. I feel less bad about my stupid mistakes now
Great video, at least it tells me I'm not the one one messing up. John is amazingly fast on the e-stops.
Cuz He has to pay himself.
3:21 I keep thinking on the scenes in Airplane 2 with the sound-operated doors!
You should post a follow up video with commentary on why each mistake was made and how to avoid it.
Thanks for that. I don’t feel so bad now.
As an amateur you often wonder what the hell am I doing wrong. Shit just happens sometimes..
In love the ones where someone is clearly hitting feed hold and trying to step it down slowly. Then goes careening into something on a Z move. 🤣
Don’t worry. I just jammed an endmill into $750 jaws the other day thanks to a solidCam glitch I didn’t catch.
Endmill breaks, peep. Endmill breaks, peep. 😂
I know the feeling, every machinist has them once in a while.
@4:12 "i'm done" -- Me at 4:30 every day
i am so thankful for these guy s making these videos. i have always been terrified of crashing a machine and getting fired immediately. thats like my feeling every day at work, but when i see that other people are crashing machines and making mistakes, it make me feel so much better about my fuck ups hahaha. thank you so much for these
I like how your machines have a beep to alert you when they crash ;)
I got my CNC machine working today (and haven't cut anything yet) This makes me feel really glad that you guys make still make mistakes but also kinda terrified lol
I do this every week in the test lab. It's fun to break tools finding the upper limits. Nice video John.
some of those look expensive
Pretty much everything is expensive when you fuck up with a CNC machine
Thanks so much for sharing this. Shows everyone is all in the same boat at times.
wonderful sliding e-stop!
Nice to see the challenges as well as the successes!
Thank you John,
your passion is always inspiring...
LOL, at least I am not the only one !!! Isn't it amazing how fast the work moves or when your end mill breaks? Oh I'll just sidestep it? NO YOU WON"T!!! Wear your eye gear or some shielding for large parts, ALWAYS! Before your brain can process it, you are wearing it in your forehead, if your lucky. Thanks for the fun. Stay safe, later.
I don't think I could handle half of those failures. Maybe I should rethink getting into machining lol
This was both hard to watch, and somewhat heartening :-) A nice reminder that everyone has these things go wrong from time to time. Thanks for sharing!
06:03 is an interesting trap for new players. (Run off the edge of a prior cut out and it switches to a laser flame cut on re-entry, that will get your attention!)
Thanks for that, made me feel SO much better about my CNC crashes. Mine are on wood crashes, less scary but still crashes!
👍👍👍👍👍👍. Great content. We all know it happens, anyone who does things makes mistakes there the best lessons we have.
Awesome video John. It's funny but I have seen some of the same crashes on manual machines. Thanks for sharing.
Most of these aren't even bad crashes, they're just work holding failures. That's gonna happen when you're pushing the limits of work holding like you guys do. I applaud your efforts, especially with the stuff I'm not brave enough to try, like the double sided tape and super glue stuff.
Oh man, this really needs to be emphasized that if you arent making mistakes you arent trying. Things happen, so easy to miss a little detail. But my number 1 rule has become if it seems not quite right, STOP! It probably isnt.
Thank you, it's always good to see the professionals screw up, makes me feel a bit better about all the bits I've broken in my learning process.
3:28, lucky its only a fan, that poor gopro :P
congratulations. my anxiety is through the roof and im incredibly angry now. im not even at work rn either
Yup, G43 H value will get you everytime. I punched a 1/4 drill through 1/4" plate one time and it didn 't even damage the drill.
This video was so helpful to me. I'm not alone! Thank you John for putting this out!
Damn this hurts to watch... seeing the cutters just rapid into hardened steel :|
Oh ya, I agree.
the problem with this is they pretty much have to run 100% speed at all time for the video wich gives them no time to react
Glad to know that everyone fucks up once and a while.
7:00 of pucker factor 10 !!!
Those pesky travel moves. Why can't we just teleport to the next start position?
Also, I now appreciate machine enclosures 10000% more.
but they are pretty much useless in cases like these: ua-cam.com/video/q_Lzw0VBu-I/v-deo.html
A lot to be said for body armor .
omg yes. had an endmill go up and headed straight for the part. was able to press feed hold just in time. travel moves pfffffff
HA! Now I don't feel so alone!
Great video. Sad to say those yellow sparks and broken end mills look all to familiar. Keep up the great work!
Good on you for sharing your learning experiences with us. Also more Judd is ok with me.
Some of those crashes really made me clinch up and initiated my reflex to hit the E-stop!
oh burning the hard jaws was the most painful to watch cuz i ve been there
Oh, that was painful...
That was hilarious. Nice to see that I'm not the only one who crashes machines.
I love that you have a furry worker there! I bet he helps lots!
I'm sorry, was this a comedy video? I was laughing most of the way through. These fails are golden!
I love CNC work when it is all dialled-in and running right, but that first run - OMFG! - is that stressful!! :(
Thanks for sharing. I feel a bit better now. :)
hahahahah now i don't feel so bad!!
:)
Same here! 👍😂
I just crashed for the first time today and I just started with this company 3 mos ago. I definitely don’t feel AS bad, but I still feel shitty for letting it happen. 😐
Hella rooks. With software too.
Loved the flaming acrylic .... As someone not in the business ( but do plenty of DIY 3D printing, and would have preferred choosing machining as a career path ) I would be interested in watching the sane video as a “directors cut” that describes what went wrong - I.e. programming error, or spindle speed too high.
Sure a lot of Z0 = (G54 + (tool offset for the old tool and the new tool is longer)) crashes in there, not that I ever have any of those ;)
@mondayfool i was thinking the same thing i ALWAYS and ever turn down the feed while machining the first part, i dont get some of these.
@mondayfool I don't, I trust my process and for the number of times something goes wrong I save a lot of time so it's a net win.
@mondayfool i would love to work in a work envirement like yours, of course sometimes it is relaxing to let those parts run but after a week or two it gets very boring.
As a machinist, I like anyone that runs their first part at 0-25% rapid and has their finger over the feed hold button.
As a CNC service tech, I like anyone that hits the go button and WALKS AWAY on the first off lol
That is why you get Heidenhain.
I remember power outages at my old work and all the machines coming to a very abrupt stop...
I remember Feb 2001...at boeing... 7.1 earthquake... machines made noise I never heard before or again...lol
Great stuff! Had a chuckle here and there! Thanks for sharing John!
Love the bloopers guys
This rivals "Scott's Tots" on the hard-to-watch-o-meter.
Bonus Points for obscure Office Reference. P.S. next time I visit, we gotta drive by the set building!
Whacha gonna do? Whacha gonna do? Make our dreams come true. 😂 ...Yeah cringes. I have done a version of I think every one of these.
Great video. Makes me feel much better about myself, thanks for being willing to share your mistakes!
I knew it! Now eager to watch even more.
So truely workholding is one of the toughest parts of machining. Apparently that and tool heights/z0 lol I admit though it is sad to see that tool crashes gets more views than a chocked full of education video like some of the others.
I love it at 1:44. I've had a few times where I've run across the shop to hit the E-stop wondering the entire way why the guy standing next to it hasn't hit it yet.
how did you set the machines up to make the bleeping sound after a crash?
Its standard on most machines. At my work we have tape over al of the speakers. Because they thought it was a good idea to have a beeping sound when a program was finished ( most irritating idea ever)
I think they mean all the bleeped swears after the crashes... LOL theres no way to mute those
Just starting to learn how to use a flatbed CNC router at work. It's great fun making it all come together to make a beautiful cut. Luckily we normally do much softer materials than I see here, but I've already seen broken bits and pieces that were grabbed and moved around at alarming speed.
Rule #1: Wear eye protection.
Rule #2: Here's the emergency stop.
Rule #3: HERE IS THE EMERGENCY STOP!
