The Evolution Of Cutting Tools
Вставка
- Опубліковано 30 січ 2020
- The story begins with how cutting tools evolved from simple paleolithic stone edges to the knives, axes and other basic metal cuttings tools via the copper, bronze, and iron age. From there we look at the discoveries of metallurgy during the industrial era, the rise of steel, and the evolution of machine tools. We explore the advancements of the tooling mills, lathes and shapers used as cutting tool materials moved from high-speed steel to carbides, and other exotic cutting materials.

Is steel an alloy?
@@dixie_rekd9601 Its a grey area. Steel is called an alloy because it is the combination of mostly iron and various elements like carbon, phosphorus, silicon, manganese, chromium, etc. These other elements enhance material properties like hardness, ductility, corrosion resistance, wear resistance of steel.
@@GearQuest ive never heard it called an alloy personally, I had always been told an alloy is an intentional blend of metals, rather than a coincidental mixture of impurities
Thank you for this amazing video!
I'm glad you no longer pop your p's when speaking into the microphone.
I am a ballistic engineer, and when i first learned why metal is so strong it was compared to paper. if you have a solid sheet of paper and apply force to it, it will rip, and the rip will continue all the way to the other side with little effort. now take the same material, paper, cut it into strands, and weave those strands together perpendicularly, if you rip that paper the rip will get stopped at the strand boundary/separation. I've never seen footage of this tangling effect on real metal grains. that was really cool how you showed grains shifting under stress
I also hadn't seen actual grains undergo plastic deformation. I would love to see a lot more of it. Also, that paper analogy is pretty good.
Amazing.
There are videos of dislocations of individual metal grains migrating as well as magnified cutting interfaces.
I don't stress this enough: there are only a handful of channels that I know within UA-cam that rival yours.
Thank you, that’s mean a lot to me.
Kreutzwerkz Arvin is quite a different theme though. It’s horses for courses.
I agree
This is the first channel that I am willing to turn notifications on for
I concur I reckon that he's in the same league as the acclaimed "Real Engineering" channel
Fantastic, this what the History Channel should be like!
Thank you. On that note, I grew up binging Modern Marvels on History channel and this channel is a direct result of that.
This is what history channel USED to be like. Same with discovery, and the science channel. I don't know where or when it went all wrong, but at least we always have UA-cam and channels like this
@@octane613 I miss the old days 😕 remember animal planet!?
History channel used to be great about ten to fiftheen years ago
Even in the best days of history channel this far surpasses it. The only thing I would change is to slow it down a bit. It's so packed with information that it would be easier to digest.

Thanks mate good work
Every video needs a comment like this
Quasi crystalline quantum computers🤓
Can someone please mention how gears could be made, before lead screw, and before machine tools i. General,
@@ryanb1874 I suggest you check out a channel named clickspring. There you will find a guy making a very delicate gear mechanism with hand tools that were available 2000 years ago
Just finishing my Mechanical Engineering degree. Amazing video! It's a very good review of material engineering and heat treatment process.
Respect - thats a tough one . Congratulations
Congrats!
My favorite part is how in depth you go into everything. That's what I look forward to! I watched this thinking it would be a brief overview of the timeline of milestones in cutting tools. It was wonderful to learn more about the process of hardening and why things are the way they are. I can always count on an educational video. I don't care if these videos take a long time to come out as long as they maintain a quality like this one.
Thank you for the motivational words! It’s very much appreciated
It's actually mind blowing how impressive it is that people in our past learned so much about metal smelting. It's not the easiest thing to just come up with one day. A complex idea, hard to just have pop up out of thin air, kind of thing..
This channel is everything that's right with UA-cam. This video was SO SIMPLE yet so informative, and as a hobbyist machinist, taught me the "Why" in relation to so many of the concepts which i already operate under. I cannot believe I'm just now seeing this - but it's one that will be watched over and over
this old Tony does a good video about cutting tools for lathes. start with a block of metal and grinding it until it's just right, explaining each and every angle as he goes from. a square
I had so many "Ohhhhhh yeah, now I get it!" moments in this video. you very clearly explained several metallurgical concepts that I never fully understood. Thank you!!
It brings me great joy to have known about your channel. It is without doubt a channel that will grow to surpass the famous engineering UA-cam's in the coming months. The content quality is amazing and in detail. As a mechanical engineer I find your work to be extremely interesting for a non engineer. Keep up the good work and may god bless you
Watching this between cycles in a machine shop! Love your videos man! I've never seen video of the crystalline change in metals before that was a trip!
Keep up the great work!
Wow, this is an incredible piece of work! It's so rare to find such densely informative content that's actually enjoyable to watch these days! Thank you for making this!
Thank you for the kind words.
As a machinist and materials science technician, I found this video to be a great presentation on tool-making and metal making processes !
If you ever need footage for your videos (free of charge) just shoot me a message, I have huge libraries of world class footage... Love your videos 😍❤️!
Thanks so much, world class you say 🤔 I might just take you up on that offer
@@NewMind @New Mind oh yeah !. Obviously that depends on the subject, I won't have everything. But my viewer request is "the history of the catalytic converter" I honestly had no idea that the catalytic converter was such a big subject, oh man do I wish I had enough time to research and learn about the history, Why it was invented, where it all started, and where it is today. After doing that episode on my Channel I quickly realized how we are in 2020 and we're still blowing about 80% of the energy of a gallon of gasoline right out of the tailpipe, and in the case of the catalytic converter, the catalytic converter is with burning most of that energy to reduce emissions, something's got to change soon, that's a lot of energy being dumped.
@@WarpedPerception but its eco cuse its being reduced in cat... thats most "funny" part for me
Cutting tools are part of my life everyday, everywhere Oh Yeah!
love your vids there nice to watch after school :)
When you are pressured to comment on everything to advertise your channel but you don’t have anything meaningful to say...
@@miles11we nailed it.
Cool initials
This channel is one of the best and most underrared on youtube. Consise, informative, good narrator and to the point without having any clickbait.
As a machinist growing in experience, this was SUPER interesting. Thank you!
your explanations of dislocations and the materials science of metal is incredible. I could have spent all day reading a textbook and not understood it as well as you showed me in one minute. Thank you!
I've seen several videos like this, and this particular one is the best by far. As the saying goes, the best tutorial is like a skirt. Short enough that it's not boring, and just long enough to cover the important bits...well done, sir.
Lol ☺️
I'm a knife collector. It was great to see how alloys evolved and powdered metallurgy covered here. A superb video.
7:38 those are kids. Holy crap! Oh, and great video BTW.
I came across this image ( www.moma.org/collection/works/46976 ) in my research and I thought it completely captured the life of a puddler. He's probably around his 30's.
They used children in coal mines, that fuelled the furnaces.
I can't even imagine the amount of research that goes into making even one of these videos. This is incredible.
Top tier content my dude. Suggestion: timestamps for the different sections would be great for longer videos
Damn! Now that is some high-quality stuff. You do a pretty great job of explaining these techniques. Having gone through years of education in this field, the serious scarcity of quality video footage was very noticeable... This stuff definitely rivals a lot of the educational material I was shown during my training. This would make a fine introduction video for several fields and jobs. Very impressive.
A very good concise and brief summary of the subject. Metallurgy is underrated and should be given more recognition, our modern way of life owes everything to it.
A high quality documentary on the history of a great topic. Thank you.
Filled with metallurgical misinformation,. Stoneworking too.
Wow. I am blown away at your vast knowledge of the subject. Such good information.
Also wonderful video production. The selection of vids and pics for visual aid helped a lot. And the layout of the video is also logical and easy to follow. Doing a historical time line and alloys, then touching on lasers and 3D printing. The subject was well covered.
Thank you for the education and entertainment. You are a pro.
I just found a very good channel for mechanical Engineering. This is how it should be taught in class.
The effort and the value of these inventions are best contemplated while standing at attention, saluting and in awe. A video like this literally make my eyes moist.
I love the way you approach the format for your videos. Informative, never dull, great editing. Great talking points. Well done.
Great video. Clear, concise and informative with zero BS filler.
7:55 I spotted an error there: cast iro has actually more carbon than all steels. It's so much that the carbon can't stay in solution and forms small graphite grains, which give the cast iron its properties (self lubrication, brittleness, good dampening of vibrations).
Pure iron however, with no or only a little carbon, is pretty soft and malluable.
Your content is PURE GOLD in a University level. Amazing. I feel like I am sitting in MIT beginners class learning about history and technology I was not expecting!!
Great Job! I have watched this twice now, and it is as refreshingly informative and well done as any I have seen on this subject. Please do keep up the awesome work.
I’m a tool sharpener my trade. This is one of the best videos I’ve ever seen, thank you
my favorite youtube channel. easiest patreon subscription decision i’ve ever made.
Every time I watch a video from this channel, I'm reminded every single time how far we've come as a species and how fast we're accelerating, and my mind gets blown all over again.
As a metal worker student, this video has been so helpful and interesting! ☺
Keep this great quality and you will be famous like real engineering and Wendover in no time.
Been subscribed since you had about 10.000 subscribers, and you are already at 150k!
This channel is growing fast and it deserves it!
Thank you! And thanks for the early support.
Superb video including the history, narration and clips used. Thank you sir!
This video makes explaining my job to friends so much easier omg
I often wonder where my career would have gone if I gad watched these kind of videos as a kid. . . Not that I’m complaining. . . I had a lot of fun in printing and computers.
Thanks for a great bunch of videos.
Wow! What a very succinct summarization of the emergence of metal forming and cutting. Well done!
The effort and time you put into these videos shows, these videos are incredible. Thank you for making these!
1:06 walk this way, master !
Fantastic video btw, never learnt so much in so little time.👍
Absolutely the best overview I've ever seen. Great effort
Thank you sir, for walking us thru the history of cutting tools, metal fabrication n alloy coatings etc. Jussojyan
Very good video, informative, up to date and addresses later exotic forms of cutting tools. A pleasure to watch for a retired toolmaker.
Dude! This video answers soooo many questions that I’ve had in life! Thanks a bunch and you’ve got a new subscriber!
Man, even the ads before videos in this channel are awesome... I had an industrial CNC laser cutter commercial 😁
U should be having a 10 million subscribers by now,.... really appreciate your hard work taken for creating one video....great work man
I was just reading of a process used by a suppressor manufacturer using new 3d printing technique that allows creation of baffles the old subtractive milling approach could never do. Thank You VERY informative
Thanks for the upload i have wanted to know this since i started machining a couple years ago
so interesting. Love your videos. Thought you wont go ino depth of the metals but more into how cutting works etc but this is great, very cool, especially with the history timeline
Awesome video! I've often wondered how one could explain dislocation theory quickly and simply and you did an amazing job!
Thanks!
A very well produced video, a classroom quality presentation. I've worked in many aspects of metal cutting in my career, currently manufacturing cutting tools, and I can attest that the information provided is accurate.
Fantastic, as always. My favourite youtube channel. Thank you for your uploads!
my college metallurgy teacher never taught most of this back in 1993.
hope things are better today.
Loving yr content m8....I'm in 3 vids and already see I'm Gina be taking in knowledge that matters....the mem vid was spot on
Well done on the research for this video. You took on some fairly complex material science and summarized it nicely. Better than any other channel in this category!
Epic, I worked in factory with a CNC milling machine, replacing these tools, setting up the product, etc. Very cool techniques behind the continuing industrial revolution that we are enjoying. :)
Wow you just explained metal crystal structures better then my material science teacher did in a whole month
This channel is literally the most underrated channel ever!!!! Far less productive education and documentary channels have millions of subscribers yet this gem is only at half a million, this is a crime!!
I work as CNC machine operator/programmer and seeing how everything evolved through the time is mindblowing. The machines we have today are so complicated and can achieve things unthinkable before that.
How things change, back then it was an achievement to get 1.5mm accuracy on 1000mm dia.
Step by step, these days a roughing cut is 10 times more accurate.
Great video btw !
This is a severely underrated channel. I love this content!
You are undoubtedly the best channel i know
This is such a masterpiece! Looking forward to more of your content bud! Keep rollin!😄💎👌
For anyone interested in the history of technology this is an excellent video. Well done!
That was a nice prepared topic.. Thank you 👍
Love your videos. Always absolutely fascinating and expertly delivered
such a sweeping and expansive explanation from handy man to latest technological innovation,keep it up bro!!
videos like these make me appreciate youtube and content creators even more!!
Excellent video as always!
Just want to thank you for all the things I've learned from this channel
You’re welcome and thank you for the kind words and support.
Thank you for this astonishing video. As always top notch content 👍
I've just learned as much in 22 minutes that I knew from previous decades. Thank you!
love this kind of content, thank you
Superbly educational - thank you. Astonishing "fact density" but also a simplicity of explanation such that non-engineers (like myself) can get a huge amount from this. Don't stop :-)
Always keeps my focused attention. Always dense with information and education. Don't ever change your formula.
Excellent video. Always wondered about late 19th century cutting tolerances behind huge steam engines. First place I’ve heard it. Thanks.
This is your best video yet! And that is actually saying quite a bit considering the quality of your content.
Wow! Great video. It's awesome watching your channel grow. Keep focusing on the high quality and the subs will continue to increase. Good job.
I feel like I'm watching a summary on the year long metallurgy course I took. Well done getting all this information in such a small video.
The production quality of this channel is exemplary!
Great video you put alot of work into this beautiful steel what a material.
Now that was a goddamn excellent mini documentary. Thank you so much!
This is so fascinating, I'm obsessed with your videos
Nice video NM! Keep up the good work; you're doing great!
Very excellent presentation. Thank you!!
Wow! These tools are so cutting edge!
I absolutely love this channel.
God damn. You have really outdone yourself this time.
I can't imagine how long this research and writing took. GREAT! JOB !!!!!
Daaaaaang you had to learn SO much to make this video. I'd have to watch it multiple times and take copious notes to pass any quiz on it.
I have never heard cast iron be called "low carbon" before. It has a carbon content above 2% and contains graphite flakes within the metal matrix.
maybe a low carbon cast iron, which would indeed be high carbon compared to a steel?
but since the context was cast iron he just stuck with low carbon in that reference frame
It was low carbon compared to its predecessors, so in the context given (chronological history of development) the statement was correct.... but I did a double take on it too :P
A "lower" carbon content would have been a better way of putting it
Ductile Iron, used for pipes and machine tools.
Incredibly cool. Thanks for posting!
Absolutely fascinating! Thanks for the video!
Another informative and beautiful video, man!
I work in a CNC shop. Some of those solid carbide endmills and indexable carbide tools are ones we use every day!
Wooow.. this vid is so detailed. I could binge! Subscribed!
