Yeah, the level of moral excellence, virtue, and integrity is clear. Theres zero mystery why our government [U.S.] is corrupt.

Love the fact that you are not afraid to share your mistakes with the world :) . But I must say that most of this mistakes are caused by not having proper shop discipline. This days that is something that often isn't properly covered during initial training. Here are a few general recommendations for anyone interested: When using 3d tasters/probes , when you get close to any object ALWAYS put your feed multiplication indicator to the lowest setting ,especially if you are going to constantly switch between computer and machine. It's always better to have to make few extra handwheel turns then to break the tip. Also notice that as you break this tips you are also causing damage to the device itself (in terms of calibration). Learn how to program on the machine using GUI (most machines have them this days). I see a lot of machinist that want to do everything on the computer , but the thing is sometimes that requires a lot of fiddling about. At the same a time lot of things can be easily done directly on the machine using predefined cycles , while at the same time minimizing risk of error do to simple and straightforward way of creating part program. You can also save a lot of time this way. If you use G-code learn how to create and use point tables. It's always good idea to have a notebook (no matter how much experience you have) where for a given part you write all the necessary information like: list and order of operations , tools used together with starting feeds and speeds , where will you place your workpoint, dimensions of your stock ,ect... Don't be that genius that "remembers everything" and then ends up making a ton of really stupid mistakes. As alternative you can use something like notepad but there is something about having a actual notebook where you can write things down. User guides and manuals exist with reason . "Real" man don't need them , but smart ones do and we use them all the time. If you are a younger guy , it pays to listen to advice from an older guy. Double check your work zero. After you take the zero simply jog the probe into x=0 , y=0 , z=0 position to check if your zero is were it needs to be. TRIPLE check your programs (especially clearance distance and feed ) and always run simulation before execution. If you are making bunch of same parts and you are using rough cut stock (that for example varies in length by a few mm) remember: the SMALLEST stock part is used to make the first part , at the same time dimensions of the LARGEST stock part are used to define your stock part in software. If you are not sure about speeds , feeds , depth of cut, ect.... remember slower and shallower is better then fast and deep to start with. When possible test your program on a scrap piece of metal. Make one part program at the time. Run one machine at the time , unless you are making a series of parts using an already tested program. On initial program run , Single Block Mode is your friend.Also if you are the guy that programmed the machine then you know where the tool needs to go , therefore you should make use of position display on the control. "I've seen other guys do it " or "It worked the last time" are stupid excuses for stupid ideas. Every machine has a set of limitations in terms of max rpm , max machining power, max part weight (also take a weight of holding fixture into account) , max travel , max tool length , max tool diameter and max tool weight. Learn what they are and abide by them. A good machinist enforces a shop discipline on himself no matter what , laziness leads to mistakes and mistakes cost money.

I'm 70. Seen a birds eye view of most of these mishaps. Every time I saw a indicator in this video I knew it was going to be toast. Thanks for sharing NYC CNC.

So I never trust anything. And hated his extreme rapid down to the parts. I always keep my hand on the stop button lol Also, one of the router we use is a Haas. I have to make sure its at full high on z or else it will rapid over in x and y and run the tool straight through a part of I run a new program. All the other machines we have go back up in z first to clear the part before they move in x or y. So that's another reason I don't like that he did it.

Picked the wrong hole. Yeah my ex wife said that quite a bit

I've been in CNC drilling and routing of PCB's since 1980 as a field service / applications engineer. I've seen just about every way a machine can destroy a circuit board. Usually, I could figure out what went wrong. The problem I didn't catch right away was the spindle was turning backwards. PCB drilling spindles are 3 phase air bearing motors that spin up to 180,000 RPM. In this case, the wiring in the connector was incorrect. Depending on the application, some drilling will work even when reversed. The hole quality will be poor and the drill point will wear quickly. Of course, the solution to a reversed rotation is to swap any two of the three phases going to that spindle.

I am so happy I found this channel. I miss working in a CNC shop. I ran everything from VF-2 to 10, SL-20s and 30s, Mori Seiki Integrex. But probably my favorite was an old OKK VM5III. It was clunky, the program was weird and backward, all of the warnings said "keep your handy parts away from moving." but it ran like a tank. Ran 100s of thousands of parts through that machine without having to replace anything.

I am new to machining, was part time for about 3 months up until about a week ago, when I accepted a full time offer. Today I made my first mistake: I didn't double check that the vice was clamped tight enough on the part, so of course it went flying and sounded like a gun shot....ended up breaking the tool. I feel so damn bad about this for some reason .....I know mistakes are learning opportunities, but I feel like not clamping down a vice enough is something not even a rookie would do. However, watching these types of videos at least helps put my mind at ease a bit. I will make damn sure never to let a mistake like this happen again!

When doing dynamic milling, it is often recomended using endmills with the most cuttingedges and agressiv spiral angel. However, this creates more liftingforce on your part, pulling the parts lose from the vise. And if you run without coolant, the endmill can come lose from the heat and pull itself down.

Then, at the last moment, as this 3x15 disk of steel was spinning at something along the lines of 3000 rpms, the cutting tool slams into the blank. The blank is ripped from the jaws, bounces off the inside bottom, then off the back side and slams into the safety glass window. The impact is so hard, it breaks 2 of the 3 panes of glass and knocks the door off the slide. In that fraction of a second, I hit the emergency stop and almost shit myself. That freaked me out so bad, I didnt run those parts for another 2 or 3 months. Mind you, I had only been doing CNC lathe work for maybe 6 months at the time. I might have 2 solid years of experience on CNC lathes/mills to date.

Is this amount of mistakes normal? I'm a CNC operator but in stone industry, and we have maybe 1 mistake every 600-800 jobs. I would need years of recording every job to create clip like this...

@@Luk_452 As far as I'm aware, the shop in these videos is mostly a self taught guy who wanted to make his own parts, and ended up moving into a job shop type business. Obviously they have experience now,but I bet a lot of their stuff is figuring out how to machine odd things and doing one-offs.

@@ScootyPuff_Jr ah... this makes a lot of sense now. I don’t know this channel,KZread recommended and it’s only video I’ve seen from NYC CNC. Thanks for taking time to explain this. Have a nice day!

"Aggressive corner" LMAO! Not many videos make me sick to my stomach but this one gets me, nice job fellas.

Love how you put your mistakes out there. We all do it. Only those who have nothing to hide show it

The spinning dial also killed me :D

I *bleep*ing laugh everytime i hear a swear word bleeped out. Love it

Thank you so much for this vid! Makes me feel so much better about my mistakes!!

Thanks for making me feel human again, good luck out there and may your offsets never be backward!

1. You’re making lots of different parts (1st runs), there’s going to be more crashes. 2. You record everything, so it’ll yeah, lots of crashes

I didn't understand it when I was in school, but now I do, why my teacher was so paranoid and strict about checking every line of code a student wanted to run on his machines.

Hi do you program manually and forget to check the tool path or do the crashes happen even using cad cam software. If software are these errors in the material types and cutting speeds or what tool library? I have done all these too. I was always programming by hand. I can laugh now watching it. But its tragic when there is a dead line and the last tool breaks.

Man, some of these are hard to watch! I though uncle bumbelfuck was a hack job with his Hass but you guys smash up your fair share of stuff also! Love your channel

Anytime you can make an endmill emit light I'm impressed!

Thanks Y'all....I am starting with cnc machining and there is about a 50% crash on each new design...You made me giggle and get back out to the machine...Cheers Jeff

Are there unit tests or something like unit tests you can set up for machines like this? Like bounds you can set in the code so that machine will never go past them?

This was harder to watch than a scary movie at night when I'm by myself.

What is the re-sale price on those machines. Asking for a friend.

Love the nonchalant raw brut force of cnc crashes. It’s like the pinnacle of comedy for me

Man, this looks like a resume of my week.

My favorite one is still the Haimer tip that goes full orbital velocity hahahaha

3:51 this is why we have "distance to go."

I saw a lot of offsets and secure part mounting issues. I’m surprised to see so many calibration gauges getting destroyed too. I manually jog when calibrating. However, I have set fire to a DHT I was cutting a part on because I hit a thumbscrew and carbon fiber dust is quite flammable.

Makes me want to keep on going, thanks for the video.

This video is giving me anxiety, I keep reaching for the emergency stop.

From a LEAN perspective, why so many issues with dovetail work holding? Is it time for a mandatory torque wrench?

@mgmjferg89

It appears a dedicated torque wrench is absolutely needed. I used a Seekonk on my Lang self centering vises (umc750ss) and as long as the material is square and you got that thing to click you were good.

anyone feel all tense watching this? Great video...just the run of the mill "when's it going to happen" anxiety hahah

Getting what carbide out? 99% of the time the part is totaled. Fuck-it-bucket and start from the beginning. Fixing the issue that broke the tool is recommended.

In the words of an old co worker for 2:34, "just dont turn the spindle on with it in it."

Thanks for sharing. It's nice to know that there are others that live a less than perfect life!

it's 3 in the morning and I am tearing up from laughing. thank you.

This is some ass clenching horror. Forget Friday the 13th and Jason. This is the ultimate fear response.

In the dawn of time when I invented the CNC machine and sent it to the future, I implemented an E-stop button. Well, I sure am glad that I did!

I watched a lot of fail vids, NEVER have I winced or grabbed my face so much in one time than this. As an engineer, watching all those poor DTI's smack into billets was just excruciatingly painful and with every nasty breakage or tool seize, I just howled NO NOOOO...

This hurt to watch... Except for the spinning indicator, that was hilarious!

I feel pain when watching. Earlier, I was laughing on others, till I made a stupid crash myself

"that's awfully close to the vise, are we sure it has enough clearance?" i said, but after finishing the phrase sparks instantly started flying
