@@CommonRailCoop Not always the operators fault when coming to bumps especially in machine shops where machines run 24/7 . I've lost count of the amount of times I've seen a z axis jump 100mm on daewoo machining centres (dodgy home switches at home position, thinks its home when hitting dog switch) or a turret losing its position on a lathe and indexing the tool off centre height or even worse the wrong tool (swedturn lathes).Tbh Its funny if its happening to someone else as you know the boss attention is not on you that day, although it feels like a car crash when it happens to me.😂

I think what really makes this hit home for me as a machinist is the audio. The number of times I've said or thought "yeah that cut is looking perfect" an instant before I blow up an end mill is... A lot. Hearing other machinists do the same exact thing makes me feel a lot better about it!

understanding the mechanics of how a vice works would be really helpful. a lot of these jobs being held on tall parallels should have been dovetailed. you can't hold a row of multiple parts in a vice. only two parts with the gap between the parts centered in the vice. etc, etc.

As a self taught machinist currently teaching myself ,I too have and continue to make some mistakes. Nothing costly , yet. I have a Wabeco 1410 LF HS with enclosure etc, and was planning to add another machine in approx 6 months. It might be the same, but since watching your videos I am considering that 1100 Tormach. I am guessing by the shirt they pay you in some way or another, but if you were to buy another machine in its price range, would you consider others out there, or jump at another 1100?

2:45-3:07 was pure gold.... no I take that back. the whole thing was pure gold John. Thanks for all the wisdom over the years. looking forward to learning with you for many more.

Thanks John, it is your honesty and humility that make your videos so great. I am still getting over the struggle of wanting to make perfect videos and just put out ok videos as I get better at shooting video and machining. I recently watched a few old (2013 era) videos of John Grimsmo in his garage with his DIY X2 CNC conversion....made me feel less bad about where I am at right now!

This video is just what I needed... My Tormach has seen it's share of broken bits, 'pushed" out of the way parts, vises that got milled over the years... Great to see that am not the only one that experiences this. I have a nice, albeit small, collection of bits in a box I made with my CNC specifically to collect these "errors".

For those of us who aren't machinists, little captions explaining what went wrong would be helpful. Some I understand, like not having the coolant/lube spray on, but others I had no idea what I was watching.

@monelfunkawitz3966

most were work pieces not being secured in vice/jaws, wrong tool offset (Causes it to plunge into the part), lack of programming stock area to include clamps on table (Tranverses across table and knocks the endmill off). Lack of coolant with carbide is not a bad thing, shocking it with coolant is.

@233kosta

For starters your mill shouldn't be able to self feed through its own rotation. That's just a bad day waiting to happen! When you're taking a cut your cutting surface should always be going in the opposite direction to your feed. For example on a clockwise spinning tool you'd do a LOT less damage running a perimeter sweep (see 4:12) going anticlockwise. It means you have to work against any backlash in your screws and gears, otherwise the tool would just pull itself in. I appreciate there's no appreciable backlash on these CNC machines, but one can see the result regardless. You pick these things up when fucking about with ancient gear that's on its last legs, such as AvE's clapped out Bridgeport. You see it all go bad first hand and hopefully - not on expensive parts and/or machine tools. Yes, it's a right pain in the arse to try and do precision work using something a professional machinist would have scrapped within the hour, but if you learn the hard way you come away a better machinist.

@salvadorebertolone

233kosta if your machine is capable, its better to climb mill as much as possible. Cuts better, leaves better surface finish, improves tool life, less load on the tool so less likely to pull the tool out of the collet, among others. You have it backwards, the best machinist is the machinist who makes the part the fastest within the specified tolerance, not who makes the best part to the called dimension, dont go chasing a tolerance that isnt called for. Even on a blown out machine you can learn to climb mill on it when you just know how much your table moves and in what directions.

There are many videos of failure to ensure the last thing in the code is raising Z height until the tool end is clear of the work before returning X and Y to home. Should always be straight up first *then* X and Y can be allowed to simultaneously move to home. You can see the fail when a machine finishes a perfect part, then plows the cutter into it.

Reminds me of the stupid stuff we used to get up to in our engineering lessons at school... unsupervised 15-year-olds in a workshop is a seriously bad idea! Two groups of us used to wind each other up, and we sabotaged the other group's open evening CNC demonstration. The CNC machine spent 15 minutes painstakingly cutting a hold-up-to-the-light relief picture of Anna Kournikova into translucent plastic. After a few sneaky changes, the head of department had all the parents huddled round watching it finish, only for the machine to pick out a massive tool, destroy the plastic, and machine a phallic symbol into the vice holding the work! So immature, but it was hilarious at the time! The moment we were left alone we were making swords, knuckle dusters, daggers, shurikens, throwing knives, you name it, we made it! We soldered hundreds of 12v piezo beepers together (each with a slightly different tone..) and hid it in the roof with a few batteries attached, making a horrible but tricky to locate whine.. we made canons out of the Co2 fire extinguisher, drew dicks onto every hidden surface imaginable, sandpapered the lenses in the laptop CD drives, and arranged every single one of the 25 laptops pointing towards the door, each one with "Meatspin" playing (along with sound, and the classroom projector running too). Unfortunately our head of year walked in before our useless teacher, and he hit the roof, bigtime! A friend's younger brother reliably informs me that our handiwork is still being found to this day, and we're still remembered as the worst class ever. I seem to remember we also took 15 soldering irons, arranged the tips into a ring and melted £50 worth of solder into a giant puck... idiots!

Do you keep your broken endmills in a jar of shame? I have kept them in a GS tool holder case and am looking for a larger container to hold them all!! I wanted to do an inventory at the end of the year to know just how much money went to my education/training. haha

Another instance is when I'm trying to explain a concept in a video and I say the wrong term, or I have to take a long pause because I forgot the right word. Admittedly, I'm still trying to find a flow that works best, but just my $.02 thus far. It's extremely rewarding though!

the moment when everybody thinks you are such a professional cnc machinist but you know that stuff like this happens over and over again.

thank you! I'm a self taught machinist as well and it is good to see that I'm not the only one making mistakes!

The Ol' KZread motto; record takes in the 20's, publish and compile once. This was great man. There's a lot to be learned from mishaps, especially when shared. Pitfalls are so easy to step into when the one ahead doesn't call 'em. Thanks for putting out the slippery when wet signs for all us newbs. Not too bad on the crashes actually, I was waiting for one that just tore a half an inch of bit through a vice, but it didn't happen. You got the balance between babysitting and letting your mill take it's steps on lockdown :)

as someone who is in teaching to become a toolmaker... i feel those. i forgot to tighten the work in the wise a few times, and it's not fun. luckily i only work on a regular mill and not on a CNC, and the parts im making so far in my internship are not critical or expensive, and they can usually be repaired

If you've ever ran a CNC this video will make your stomach twist.

Always wondered why my father taught me extreme measures mounting a part to be machined.. Shit can get hairy quick. Cool video glad to see everyone still in one piece.

the air pipe hitting the camera and coming off the job, then it burning up HAHA.. so much precision and prep from these machines but it still can't account for a silly human error XD

not as meany broken end mills as i thought. keep up the good work

Glad to see some good hardy humor mixed in with all of this knowledge. Never a dry episode!

I can’t imagine setting up a machine. Then setting up a camera. Then publishing the mistakes. Well done! ;-)

we need more of these crashes :D

So nice to see that even the best make mistakes. Thank you for making some of these mistakes for me so that I didn't have to learn them. I DID find out however, that a #51 drill will plunge in at 20+ IPM at 10K rpm because I set T26 but not H26 lol.

Oh man.... I tried watching... I cant. I was cringing all through this!!

It's amazing these contraptions work at all

Breaking a 3D dial tip on a pumpkin has to be the saddest feeling. Love the videos!

Now i feel much better, ive snapped bits for various reasons and figured a real machinist wouldn't do that. Thanks.

I think it is great you guys are not afraid to admit you are human. anybody that tells you that they never crash are lying. I did CNC turning for 15 years mostly on Mazaks. Never got into milling too much.

tis the year of the great pumpkin Haimer crash nice video John, I was finale able to buy a lathe just a 9 / 20 inch but the price was right .wile you mostly mill you have still taught me a lot and I truly appreciate it. Thank you

I will never forget the first time I had to tell my boss I broke a tool. He said "well it looks like your a real operator now"

Part of learning to machine on manual machines is that you get a 'feel' for what you can get away with on part holding. The feedback from a handle is nice to teach you how much tool pressure you will have in a certain situation. Most of my part holding is with vacuum, so it is very important to understand it as once you lose vac, you lost the part. Starting out on a cnc makes it a little harder I think, you don't have that feedback from your hands, just sight and sound which are fine once experience has informed you what they mean. Thanks for the videos...
