Yeah American schools are horseshit. In the uk you can choose to go to university or you can learn a vocation even earlier than when you would normally leave for uni. There’s no option like this in America, you either know about this stuff from a family member or friend or you don’t even realize what’s there
@@coheedmonstar33 This is not entirely true. We did used to have these programs in the high shcools but where i live we have a robust vcational school system that allows students from all schools in a fairly large system to take these classes rather than just what could be offered on campus at a higher cost. Most of these programs are available in their last 2 years of public school. Sadly there is a strong emphasis on college and many in our educaiton system seem to have stopped carign for kids not on that track but with programs like our vocational prgram, especially where they have partnered with the local communit college system kids have some great opportunities. Of the two most successful people I know one is an accountant, the other is a plumber. Only one of them owns their own business.
The Lord used this message you wrote to remind me to pull my safety sunglasses out of one of my work bags i leave at home and, put it in my lunchbox to take to work with me tonight. Thank you.
Just checking this out for a friend, who's looking at training in machining for his profession. This is genuinely fascinating, and good comparison between manual and computer controlled machining.
My son is going to look at CNC schooling next week, he just came back from Navy boot camp because he could not meet the minimum requirements for running. I am excited for him to check out the CNC field!
I'm starting a new job in this trade so I needed to do as much research as possible! Ive done hours of monotonous research before I found this guy! His presentation technique and enthusiasm makes absorbing this sort of information much easier and even enjoyable. EXCELENT introduction sir, thank you very much.
Hi John, I just feel like re-doing machinist school...! Young one ones NEED the support and encouragement and people to look up to. Fun that the teacher called on you to show, and even nicer of you eagerly responding. Cheers, Pierre
G’day John, my name is Aaron and I’m a Technology teacher located in Melbourne Australia. I’m also the manager of the our Trade Center, Harvester Technical College. Just want to give you a shout out and support what you said mate. Never a truer word spoken and I couldn't agree more with you. We are having the same issues over here in Australia. Lots of kids want to be builders and plumbers, but most have no idea about engineering (machining / fabrication). It blows them away when I bring them into my engineering room and show them all our gear (manual & CNC). It also probably doesn't help when the manufactures (Ford, GM & Toyota) are leaving this country in droves. The STEM movement is slowing gaining momentum in Australia also. We’ve just got to keep on fighting the good fight. Check out my channel if you get time. All the best mate, Aaron.
NYC CNC Hi John, thanks for getting back to me. Totally agree, nothing like a VMC spinning bits and ripping chips to get the student's attention. I use the HAAS gear at school, plasmaCAM, 3D printers and Epilog laser as a hook to rope them in. It's like bees to honey. Cheers, Aaron (Melb, Aust).
Hi Aaron, what future does manufacturing have in Australia? I think it is dead, and won't be coming back to life. Successive governments since the 1980's have done everything they can to make sure that manufacturing is no longer viable in this country and have "dumbed down" the education in this sector, ie no more tech schools. Mining and real estate was seen as our savior but mining is done, and many would say real estate is in a massive bubble ready to pop. Australia is going to find it tough going forward. A country the doesn't manufacture, has no future. Just wait until Holden shuts down, the shit will really hit the fan. Don't want to be negative, but I can't see how this will end well.
Grant Patullo Hey Grant. You make a very valid point. I've spoken quite a bit about this throughout the past years and to anyone that would listen. Unfortunately I foresee a nation of coffee shops, and nobody with any money to buy a cup. Both Governments past and present have much to answer for the demise of manufacturing. I see a couple of answers, bring back tariff protection and process our raw minerals here in Australia. Yes, the Tech schools were shut in Victoria. Labor started it and the Libs finished them off. Thankfully, some (like the one I'm at) have returned under the Rudd Govt trade training funding. However, many were built as a big shiny buildings with no equipment in them. Their educational outcomes were the use of coping saws and spoke shavers. Little to none CAD-CAM-CNC education. My engineering students are doing well and getting employed (apprenticeships) at small job shops, fabricators, medium - large industry and Govt sectors. Maybe we need our own home grown version of the USA TV reality show #titanamericanbuilt that showcases some awesome Australian manufacturing. Great chatting with you Grant. Cheers, Aaron.
DCTTeacher1 Grant Patullo What's happening in Australia happened in the UK decades ago, and arguably happened to a certain extent in NZ a long time ago as well. Manufacturing isn't dead, it's just dead as you have known it. I'll see if I can find a recorded link somewhere, but Paul Bohannon did an excellent job of presenting future options for manufacturing in Australia at AU Extension in Sydney last year. It is about adapting to the situation, people & companies will always need stuff made locally. Machine & professional software costs are coming down, it's about being dynamic & innovative. I have no doubt that a number of Aaron's students will go on to make waves. We definitely need more tutors with the level of passion Aaron has.... that applies across all subjects.
Hi Scott, I was going to add that I think the smaller operators with lower overheads could adapt but bigger operations that have all there eggs in one basket are going to struggle. And we also have the big fish eating up the smaller ones with mining at the moment. So we'll see how that turns out. There will always be a need for engineering and manufacturing but like you say it just won't be like it was.
John, I have a hunch that you were paying your sole employee his normal hourly wage to operate the camera. This video not only cost you your (increasingly valuable) time, but money out of the coffers to pay your employee too. Thank you for going out of your way to help educate our youth! I do the same thing as an adult volunteer with the U.S. Naval Sea Cadet Corps. The little that I contribute is very gratifyiong and I hope you feel the same. Your Videographer did an outstanding job! I like the format a lot!
NYC CNC I agree, I like the fomrat and video, however, the dolly left to right and back again over and over the first 2 minutes was a bit much. lol Perhaps it was just a bit distracting to me with the background continually moving. Squirl!
NYC CNC John, I love the videos. We have several machines at our community and would love to make videos. Was wondering what camera you use for your videos and what software you use to edit?
@@StarlightEater make sure you dont mention that to anyone. fake it till you make it. seriously you mention that to a boss and hes wondering what else youre bad at because math is not hard at all when you try to learn it especially the easy repetitive math you have to do with this shit
Thank you John for taking time to explain this process from A to Z making the difference between a manual and a CNC milling machine. This is my very first time watching your channel and I fall in love with it and have some flashbacks. I used to teach machine tools technology for nine years in the 80's and the early 90's. Since I left my country for more than 25 years, I never have a chance to touch a machine tool. But, I still have the desire to build my own shop. After watching this video, I'm so happy just like it was myself operating the machine. I'm a subscriber now and won't miss any other. Great job!!! Keep it up and thanks again. 👍👍👍👍👍
Hello and thanks for the info, I watched your vid a long while ago when I started to learn both the manual and CNC mill and lathe at my first makerspace job, then that was intimidating - and now I am starting to learn milling with a KUKA arm in my latest job which I never would have thought I would be able to do as a kid. Tiny, helpful education can amount to such big things especially when it's not condescending and seems to genuinely care about making people interested and excited to learn.
NYC CNC This was spot on introduction to machining. It shows the exact very basics in short time and not boring kids with too much detail which could easily happen in such vast topic as machining , but yet it's the this kind of "keep it simple stuff" that might get someone interested in learning more about it. Very good job. Personally I think manufacturing precision and like is something that will come up in various other job related topics and might indeed bore students. Although it might have been good to show somekind of complex cnc machined part at the end briefly just to see what can be achieved by computer aided machining versus "old machining". I hope some teacher would happen to read this end as adult looking back, I would've loved to see precision metal working examples as "whole". We never saw examples for the big picture seeing ie. machined parts assembled in to bigger constructions. These kind of examples would've make me appreciate metals works as industry whole lot sooner than it did. I really hope teaching has evolved in this area.
Thanks for the video! I want to go into machining, but I have to get some training first. And everyone gives me crazy looks and reactions when I tell them I want to be a machinist. If I were a man, they probably wouldn't be like that, so I'm just going to ignore them.
Hopefully people are slowly becoming more accepting of female machinists. Definitely ignore those people, and don't let the crazy looks stop you from doing what you wanna do!!
Yes ignore them. I have been a machinist, welder, metal worker for 30 years. It is a great and creative career. I make good money and enjoy everyday at work. Go for it and best of luck to you.
Hey NYC CNC , Thanks for showing that video and I hope that the young people that watch this will really take to heart what you said. I graduated school in 1981 ( I am now one of those old guys ) and my shop teacher was one of the best teachers that I ever had. After school I went into the army and when I got out, I got in the electrical field that I learned in school, and for 25 years I have been blessed to have a job at the same company doing what I love, and that is being a Lineman. I do machine work in my shop and this is something I really enjoy, and I learn a lot from watching all these video's that people like you take time to make. Thanks Buddy
Ok first kids : ALL WAYS LOOK AT THE TOP OF THIS BRIDGE PORT! Because SOMETIMES the person before you might of left the wrench ON THE TOP OF THE SPINDLE!!! It's used to tighten the spindle chuck👍 Make sure it's CLEAR! Because you will ether BREAK the spindle spline OR you will FLING THAT WRENCH like a rocket and kill someone OR a combination of both 😵And if you want your parts to be CORRECT! You must edge find your clamp or chuck jaws! MaKe sure your clamp & clamp jaws are good and tight !!! Because if they move AT ALL YOUR ZERO IS GONE & you will need to re-edge find all over again! AND ZERO THE X,Y,Z on the small computer looking box with the digital readout , with a tool called a edge finder!!! That is your point of zero/ Origin Unless the machine is zeroed out already,but that hardly the case! AND ALSO VERY IMPORTANT!!! If at anytime you remove your work pice from your clamp. YOU LOST YOUR ZERO! Unless you have god like hands that can tighten and place the work pice back Precisely , exactly , BACK the way it was in the clamp jaws EVEN IF YOU HAVE BUMP STOP!!! Always trying to finish your operation without removing the work pice!!! Because if you're trying to hold a moderately tight tolerance we will say +_ .005 you could easily lose that by removing the part out if the jaws!! Especially if you're trying to hold .0001 just forget about it trust me ! & a (WARNING) PIN BACK ALL LONG HAIR, ROLL UP LONG SLEEVES,NEVER TRY AND WIPE THE WORK PICE WHILST THE SPINDLE IS MOVING!!!!!! If you try and wipe coolant,tapping oil, whatever with shop rags while the spindle is on IT COULD PULL YOUR HAND IN !!! You are NOT fast enough to let the rag go before the spindle grabs the rag in and BOOOOM your hand is no more!!! ALWAYS TURN THE MACHINE OFF!!!! and of coarse safety glasses 👍
I've been machining for 20 years now. Mills getting progressively bigger till currently working on 15 tonne workpieces Glad I learnt after being caught by my sleeve on a Bridgeport mill 18 years ago and escaped with just bruising with friction burns. Only because my right knee had the sense to hit emergency stop on the way in. Plz do not think these are toys,I got lucky as the 50mm face mill inserts were not sharp like an endmill. Stay safe and turn off moving parts before placing anything you can't afford to lose near them.
i thought of the same thing when i took my cnc course. if you think of it tiny metal dust particles are around the air you breathe. so technically i guess it could be safe if you wear one. like they say safety first.
I am thinking about getting into STEM. I have always been in the medical field, but my daughter wanted a 3D printer for Christmas. So my stepdad got her an Ender 3 and I have had to give myself a crash course in how those work and had found it fascinating. I already have 2 medical science degrees (medical receptionist and certified surgical technologist) but just got back into school for my third degree, radiologic technology, but now I'm seriously considering changing my major to CNC machinist and see where that takes me.
It's been a while since I heard "a thousandth" in machining. I think it was the first time I did it actually. Since then every machining job I've had has been on the metric "micron" system.
Never got into or understood STEM and CNC and honestly didn't know much about it; but after working as a Wire EDM operator for about a year and leaning various things. I've been considering going over to Milling so this is genuinely fascinating so thank you for the video and explanation.
Gotta love educational videos like this, actually helps a bit since planning to kick start my metal fab course in January (wanting to start a small machining company in Texas, idk if in East Texas or CenTex atm).
+NYC CNC I've started watching great channels like yours and even taking some Lynda.com classes on it. I'm wanting to get an X Carve from inventables to play around with. I'm fumbling around sketch up but not having much success with it. Guess I just need more time behind the mouse with it.
I know absolutely nothing about machining other than the (admittedly hundreds) of videos I've watched on RU-vid, but what does this bridgeport do that your tormach can't? Why was buying it such a necessity for you? (excuse me if this is an overly ignorant question!)
NYC CNC Awesome, thanks for the answer! I live in a tiny apartment (with no basement) in Denver so any kind of real machining for me is a pipe dream (I keep my engineering on the computer end of the spectrum, mostly programming). I did a bit of gunsmithing and general farm-related machining growing up on a large farm in Central Kentucky though, so I can definitely relate to your love of being back on the farm in Ohio. I love watching your videos though, I get to satiate my yearning by living through them, ha! Keep up the great work!
Hi,i'm an 18 year old from Singapore and am very new to all of this. I'm currently studying Laser and Tooling Technology and this is part of it. I just wanna say this video has helped me understand alot more in depth and for that,I thank you :)
Great video, I was wondering, since you mentioned building the pen plotter, would you be able to advise, or offer any help. I'm wanting to make a guitar pickup winding machine, but something cnc controlled that will count number of winds, has a left right travel and a bobbin holder.
cool video heyy im 30 years old do you think im still on time to get in cnc machining ? , and you said the bridgeport mill machine is about 2000 dollars , how much is the tormach cnc version of the bridgeport that you used?
Hi, how are you I live in Brazil and I have 25 years of manual machinist experience. would it be difficult to get a job there in the USA with all this experience? thank you.

John I want to go to school to be a machinist so bad! I just can’t get anyone to give me a chance. I’m a 4 1/2 year almost 5 year recovering attic and I can’t get nobody to give me a chance man I just want to be a machine is so bad I have a lot of my own tools I have a South Bend 8 inch Dalton six-a type 4. I love machining
Been years since I've operated any machine, though I can close my eyes and still smell the smell, hear the tools running through metal and can still see that almost orgasmic machine finish. There's nothing like it, the finish that is, of a properly machined piece of metal.
I miss manufacturing. I hate being a service technician. I started machining in 1991 for Bardwell & McAlister Lighting & Grip. I learned how to use manual lathes and mills. I also learned how to TIG weld from a Miller employee. I think I need to give notice.
Thanks for the video John! I've been wanting to start with machining for a while but never really knew where, so this really helped me. If only I had the money to buy the tools! You have given me a place to start so I'm no longer clueless, thank you!
Trump and his damn pact act fucking over manufacturers has made me so angry that im learning machining and producing my own vape atomizers. I have watched tons of machining videos but never with the goal of learning it myself. Thanks for the video! I do wish it wasn’t so expensive to get started though, lol.
Problem is they advertise STEM careers to pay more than they actually do and its hard to get into the field of study cause they always want to place you in an unrelated field or similar field. You can want to be an engineer and end up only being able to find a job in research testing which is quite boring. In my case I have an electronics engineering degree, now I have to go back to school and take two classes not included in my program and pay out of pocket cause nobody will hire me without CNC programming. Thanks to the college not informing me and adding these courses to my program. 🙄
You milling wrong way round. It is actually backwards. The chips should fly to the back of the tool. In this case the chips can stuck between the tool and the part cause flying front of the tool and making knurled surface if you know what i've mean.
Machining is such a sneaky way of learning , math, physics, electronics, chemistry, even a little biology from the occasional skinned knuckle. Start managing a shop and add statistics, accounting, finance and human relations. The practical application of of all of these disciplines give you the tools to be a better machinist and a true artisan.
More people just need to understand that in this Field you can do just about ANYTHING you can go ANYWHERE and Get a GREAT paying job the sky is literally the Limit and doesn't require a Degree but more often then not you Get DEGREE Money without the Degree Debt and isn't going to break your back. Most dudes straight out of High school Go to College. Military, Service industry or Straight up Sweat shops that have sky high turnover, when they could be making BANK and having a good time doing it.
PLEASE ADVISE.. so im a machinist who is building my own home shop. Naturally a get hit smack in the face with the 3 phase problem. You have any experience with bridgeport using single phase 220 by way of a VFD.. is it worth it, does it work well? Basicly, do i move forward with a single phase Precision Matthew bridgeport clone or a frankensteined bridgeport controling my variable speed with a seperate control? I need advice an quick.. Thanks to everyone who chimes in..
Welding is only one small part of fabrication. I don't understand someone that learns only one aspect of something that has 15 different layers to be a serious fabricator.
Nice video....I'm an electrical engineering student and I believe all engineers should be familiar with how these shop machines operate as opposed to theory-based knowledge. Especially working at a shop and some engineers have no clue how some stuff works....
50 years ago, this kind of stuff were must have skills if you wanted to get a job. Now machining is essentially a rich mans hobby. Lots of people can't even afford the tools and don't even have the space.
Welding is easy. Well, it's really not easy at all. But as someone who has plenty of experience and is somewhat proficient in both areas (self proclaimed) i definitely feel machining, whether it be manual or cnc, is way more brain heavy and involved than gluing some metal together. (Intentionally downplaying welding for dramatic effect)
Do you have a guide, playlist, website or book that I can start using to gain knowledge? I have zero clue about anything in the trade space and every time I look get paralyzed on choice and stop looking just to come back later.
Ive been researching this for a long time and can't seem to find a real answer.... is there any desktop or moderately sized cnc mill thats capable of cutting steel like pistol slides?? PLEASE HELP
2 flute end mill? Slot drill, not the best tool, end mills can't cut downwards, slot drills can due to their design. You can mod a Bridgeport to CNC , I've worked on them , over 30 years old upgraded fine.
I operated A CNC TURNING CENTER WITH 2 AXIS. MACHINING DISC BRAK ROTERS I LOVE BEING S MACHINIST BUT OUR COMPANY WAS CLOSED.I ENCOURAGE YOUNG PEOPLE TO GET INTO MACHINIST SUCH A FACINATING TRADE.
The problem with machining compared to the other trades is the income-to-hassle ratio is terrible. In most markets a machinist earns at least $10/hr less than a welder, plumber, or electrician. Not to mention the other trades are much less susceptible to overseas-outsourcing.
Is it true that CNC operators will be replaced with robots within 3-4 years (or maybe just a little later) and just the CNC programmer position will stay for human?
How does the CNC know where the material it needs to cut is? If I wanted to cut a smiley face out of a piece of wood, how would it know not only the X and Y of where to put the first eye, but also how far down and how fast it needs to go in order to not destroy the bit or the material? I just got a $250 hobby/intro CNC and I’m scared of using it because of this. Any tips?

There's a huge difference between being a production machinist and not..production machining is boring and repetitive,higher up team leaders and so on write your programing and you just find your work shift then run.not much fun
Same thing upstand ny we got boxes at my high school and if you signed up you got to pick a trade to learn and instead of your hs they would drive the kids to wemoco for a few hours and the welding and machining classes were 50/50 the first year and your senior year you have to pick one to stick with and we had at least 40 kids in my class and only 7 chose machining, I picked machining and all seven of us got co op contracts and got jobs before we even graduated and the welders out if the entire class I don't think they got any
Hi Great things you are doing here ,I am Already a cnc programmer and user but i lack some basics i want to know how to get manual for The cnc i am using i have the model of the computer hand i am using is that enough ? i want to be able to know how to learn to work on any cnc not only my machine.
Hi, I’m just getting started off with CNC machining for hobby/specialty part manufacturing to reproduce parts for vintage paintball guns. I’m considering the Haas Mini Mill since they seem very user friendly when equipped with probing system and dynamic work offset/tool center point control. For the work I want to complete I need 5 axis milling. Is it possible to use a 4-axis machine then rotate the part 180 degrees re-mount and mill what would’ve been the “5th axis” if the part was milled in one step on a 5-axis machine. Or will this cause accuracy issues between steps in the milling process or just over complicated the program to run. Adding the tilt and rotary nearly double the cost of a 3-axis machine. If re position a work in progress is manageable (not sure if the probing system would help in this situation ) it could be worth the savings. But if it causes more headaches that it’s worth I wouldn’t want to end up kicking myself over saving $12k upfront cost. Also are there any smaller machines on the market capable of being optioned out with a master/slave for 5-axis milling? Most of the parts I want to mill are very small (1”-7”) with the odd item being around 12”x5”x1.5”. Accuracy and finish quality are very important which is why the Haas products have caught my eye but if there are smaller machines on the market it would be better on my budget/space limitations. I’ve searched for machines a lot but manufacture don’t exactly advertise their offerings very well making it hard to find for people outside the industry. Any information would be useful. Thanks!
It is really helpful who is trust to learn more.I appreciate that those who made easy us to re-study again and remember us the Africans that what we learned before.I one who is behave the somalin machine shop engineers to take this chance no one befit.
Brings back memories of my machining days using a Ikegai AX25N lathe with a Fanuc 6T control and a OKK mill with a Mitsubishi control. Around thirty years ago 😄. I do miss it.
Great job John, you may have covered it before, but I'm curious as a family home shop hobbyist (looking for semi retirement) my wife and grown daughter are pretty artistic but I'm more of a fabricator/builder. I wonder if there are ways to get into simple/inexpensive engraving. Just to put names on parts to personalize for people, like for something to set on desk or something. I do have manual lathes and mill. Thanks
Y would you move your quill in z wen the table moves the same you just added another factor into things that can go wrong as far as chatter and tooling over loading
