This is a modern miracle. I can imagine the hours of work, put in by mechanical, metallurgists, electrical software, toolmakers, and all the logic that went behind the scenes not only the logic of the cutters but that tool changing and the coordination of the degreesof freedom involved. I like the manner in which the crankpins are made. I must not forget the mathematicians who coordinated the steps to cut. A modern miracle indeed that few can appreciate. In the old days , the product was more beautiful than the tools used to make it but in modern times the tool is more beautiful than the product.
Those cutting depths are phenomenal. I also like the optimisation of the fast travel; when the cut is finished the tool doesn't just go back to where it started but rather goes on in the same direction, which is much shorter, and starts to cut from there. Great video!
As a former CNC programmer : Respect. So many tools , so many parameters, , so many spindel speeds, feed rates, so many hours of programming and simulating.
Incredibly,beautiful work.knowing what I know about such things, I can only imagine the thousands of hours of machine design, cad hours, programming ,not to mention tool design and application,to make such magic appear for all to enjoy on youtube. My hats off to all who made it possible. I've always said " humans make space ships out of dirt"
I make furniture from large slabs of wood, trees cut by chainsaw and millied on my property trees which I planted 20 yrs ago. There's a world of difference with the precision and high cost of the tooling in the video - yet some concepts are similar. I liked the video!.
This took a lot of team effort by metallurgical, computer, and manufacturing engineers as far as I can see. Hopefully society will learn to have a higher respect for engineers after watching RUclips videos like this. They help us to enjoy the good life. Nice cars etc. Every September the news media shows university students having this good time. They never talk about the engineering students who upon arriving at university have to almost immediately immerse themselves in heavy mathematics, physics, and working the computers from morning to late night almost everyday from September to April. They are under a lot of stress, and they have to achieve high grades. Only so many people out there can achieve a university engineering degree.
Mechanics and technicians will always curse automotive engineers because of the stupid things they have to replace in the impossible to reach places, as well as bad design flaws.....
Ageed. An Engineer is a certain breed of person for sure. Highly analytical but also with very keen visual and spatial abilities. Kind of the bridge between art and science but skilled in both !!
What an awesome piece of machinery. The things you could make with that once you were trained properly, are only limited to imagination. It makes bridgeports, drill presses and lathes look like fisher-price toys.
I have been in this type of manufacturing my entire working life (not going to say how long that is .. ) but I wonder the same thing! I went through the engine room of the Queen Mary (keel laid 1931) some years ago and looked at the giant gears and shafts and was in awe ..
One hundred years ago, men did this with slide rules and their wits. It took a lot longer to complete. The same kind of men put this into a computer program and made life much easier for the machinist. People who build machines like this are my hero's.
+sam schrenker Programmers and Engineers are the bane of a machinist's world! We're the on the ground operative... but they don't want to hear a word of what we have to say. What does that plebe know? Don't get me started. And I did engineering work, AutoCAD, for 17 years. I prefer cutting metal in a shop.
My son just started machine tool in trade school. I graduated from the same school 32 years ago as an automotive technician. A trade is the best education you can receive . With manufacturing returning to the US a trade is your best bet in today's market place.
Joseph Matarese You've got that right. For years, people have been getting out of collage with the idea of being a suit. It's getting very hard to find people that can actually produce anything and there are way to many suits for the amount of jobs.
Having been a manual machinist I'm amazed by many aspects of the CNC process. Like for instance how it knows which tools need cutting oil. How no matter how long the tool is it never chatters. How fast the tool spins. (doing it manually you would never turn the cutter head at like 4,000 rpms and certainly not without cutting oil.but this machine does it successfully) How its taps as fast as it does. How it speeds up right in the middle of a cut once it reaches a part that has continuous metal and knows it won't beat up the bit. How it takes off like .600" per cut while turning the lathe portion. and most, how it takes the perfect amount of material off per cut to get a smooth , shiny finish. I know from experience that when you get close to your desired size, you take small amounts off. And when doing so, the finish often times is not smooth and shiny. The machine (or programmer) knows how much to take off on its final pass to achieve a smooth, presentable finish. I realize it will all get polished anyway, but there is something satisfying about a sweet looking final cut. And of course there is the machine itself. It has like 50 tool heads. A door opens and an arm comes out, inserts a tool, then the arm goes back in and the door closes like something from The Jetsons. It lathes, it mills at any angle, it drills at any angle, it taps at any angle. Then the head turns 180 degrees and it spins the other way on a dime, and does the same things the other direction. Amazing. Maybe i'm making a bigger deal out of it than it really is....... But I don't think so. There are things made on a CNC machine that simply can't be made any other way. All while maintaining strict tolerances.
There is also the thing that CNC programming is not quite like just programming. You have to have a great deal of hands-on (technical) experience to accomplish something of this size.
MrMarkpark Yeah, I agree this video is amazing, and I also wonder, for example, how is the cilindricity of the crankpin journal, since it's machined controlling the spin rotation and the miller head simultaneously.The bad quality finish when machining a last little portion is probably due to the depth of cut being equal or smaller than the tool "sharpness" radius, so as it does not properly cut the metal but actually extruded and ploughs some little bits of material. The choice of using or not oil usually comes from a lot of research regarding cutting a material A with a carbide B, within parameters of cutting speed, feed and depth of cut, then evaluating the life time with or without oil, etc.
This is amazing, but I find more amazing that people with just creativity and craftsmanship were able to do this 100 year ago and still have the same level of precision .
They weren't nearly as precise as CNC. They could still make good parts and knowing how to use manual machinery is important, but CNC is where it's at. One of my tenants has a CNC shop and not one of his guys can run a old Bridgeport. If the computer goes down no parts are made. Kinda sad really, they're programmers not machinists
It's a thing o' beauty to watch it go through that process. The guy who set it up, who had to work out the different sections of the program, needs a good pat on the back too. :)
Yes, the machine can be programmed and set-up to make anything. From a Porsche 930 Turbo crank to a landing gear for a 747. We are a dealer fpr the equipment. Unfortunately, we don't offer machining services.
Watching this video is just a thing of beauty... Wish I could just afford to buy one of these cranks to hang on my wall in my living room.. Automotive Art! And what an awesome CNC Machine! :)
Brilliant! I just love the different crank-throw counterweight, based on the overall balance when the engine is assembled. I was look out for this in particular but you did not disappoint! Of course, we know that crankshafts should be machined from a drop-forged blank but your video goes to show that it's also viable from a straight bar. Well done, sir.
+Gordon Burns That used to be the case but not any longer. As Shepherd Ginzburg correctly points out above: "No, we use billet cranks for strength. MichaelkinsfordGray is correct in entirety. When you build a top fuel racing engine that makes 8,000 horsepower, only a billet crankshaft will survive. Even then you are lucky to get 10 passes out of it before cracks appear."
To answer a question, all Top Fuel engines have a billet crankshafts,blocks, heads, cams, whole superchargers,etc. along with with many other high end race cars, bikes,boats, planes etc. Very pricey items made to survive severe use. I work on a 5 axis machining center and manually program for prototyping. A thinking man's way to have fun. Computers are our friends!
After fifty years of toolroom work, there was always an argument about who was the most important, the engineer, the cad cam programmer, the machinist. After all those years, I still love the sound of heavy chips raining down into a chip pan. Those tool holders are amazing to see. The person that programs parts like this, is earning his/her pay.
since when i was kid seeing the tv shows about cars always question me how fabrique this part of the engine now i know it. in some way this is inspirings me
It was an absolute treat to see this process unfold! The level of skill necessary to create such a machine and then program the operation is quite astounding. What engine is the crank shaft for?
Damn I loved watching this. I'm a retired CNC Machinist. I actually miss setting up and running these things, just don't miss the hours of working 2nd shift till 1 am. LOL

I watched a team of machinists in a workshop using machines up to 100 years old make crankshafts by eyeball measurements and you know it's rough but awesome, then you watch a computer programmed by a master machinist and the result is flawless and likely double the performance from a given engine. CNC machining is beautiful to watch.
What impresses me the most is the intelligence and knowledge that must go into the design and construction of such a complex and versatile machine and I should have written why is ,cooling not required in some instances.A most interesting video.Thank you.
Hope my previous answer helps, but to add to it.... For this type of steel, where the chips can freely evacuate the work area, the heat leaves with the chip. (Heat is always the killer). For the drilling operations (for example) the chips would Gaul because they can not be freely evacuated. The coolant both cools and helps to push the chips out.
MARTECHcnc Thank you for the info.I should have thought of that myself.Steel being not simply one substance.Once again,thank you and keep up the good work.
I've worked on a Mori Seiki MT253 5 axis. The machine was epic but the parts weren't. Now I'm on a 20 year old 3 axis mill. I'd go back to the Mori any given time.
I have intimate experience with both the Mori NT Series and the WFL. Although the Mori is not a bad machine, it is not in the same class as the WFL. The machine construction is completely different. One important point about the WFL, is that they build ONLY MillTurns. That has and continues to be their focus.
Loukas Dimitriou Hello - If you would like to make an inquiry, please visit our website and use the machine inquiry form. The machines are typically configured and quoted after through review of your application. Thank you for your interest.
Had a guy taping me doing some cutting on a Okuma 5 axis lathe a few years back. He was begging me to run it with the door open for a better shot. Had to laugh when i said, are you going to hire me after they see the film and fire me lol because it would have been the end of my job given where i was at the time.
Thank you for a great video! Is that the crankshaft for an engine? Looks to me like a triple or, more likely, a V6...With staggered crank pins on number 1 & 2??? More info would be appreciated!
It's just a demo crank, it is to show the machining operations that this particular machine can do. This crank shaft will not run in a car. However, the split journals are for even fire v6's, so there are vehicles that run the split journal style crankshaft.
autofixation It looks like they've got multiple style journals on this. Some single, some dual. I will say this: Audi/VW loves to use that split throw style setup, I've seen it multiple times in their 2.7 V6 engines.
With today's modern software, complex components like this crank can be programmed and the program/tools 3D Modeled. Most of our users are working with very expensive alloys and/or castings. Trial & Error or scrapping out the first few "test" pieces, is simply not an option. No wood used.
This was probably programmed based on a model in solid works, module works or some similar cad program. All the tool paths were programmed there based on the precise footprint of the tool. As it is an improperly programmed CNC mill won't generally destroy the work piece, but rather its tools with improperly set feeds and tool speeds, which is often times a more expensive error than if the mill just destroyed the work piece with an improper cut.. With a large piece like this likely not, but often you'll be working smaller parts like fittings, adapters, or spacers. Where the cost of the material is far below the cost of the tools.
grame141 I'm pretty sure that you have to set a strategy for it to follow, and that you have lots of of choices in the process that follows. I've only done some more basic cnc milling though.
The software will create its own paths which you can alter but the g-code is automatically generated. it's possible to alter the code afterwards but there's no instance where you would have to manually write the programme yourself from scratch. At most you would have to make some corrections after running a simulated cut.
grame141 grame141 - you are pretty much on track. First a model would be created, then the file imported into the CAM software. Tool selection and order of operations is interactive as part of the software package.
MARTECHcnc Absolutely AMAZING that so much can be done on one machine and with such precision and speed. At 13:22, I believe it shows the surface for the connecting rod bearings. There must be another, final step to make that surface sufficiently smooth and round enough for bearings. How is this step performed?
this is some seriously serious shit! I'm guessing this was programed by a computer where the dimensions/parameters of the object were given and the computer derived the code to make it work. If it was programed by a human or team thereof they are some bad mfkrs!
+Louis Balboa all CNC s work with CAD inputs that means it was first designed in PC by engineer and CAD programmer then CAD design was done by CNC like a 3d printer roughly.
When you use some CAD & CAM program like Mastercam or NX it is not so difficult to make this kind of part. I can even say it is quite simple because this program calculate for you everything. Of course it is possible to do this kind of part manually on control panel as well. You have to just focus on 1 operation at the moment and then when you done with this one just proceed to next one. No rush! Quality first :)
You would have to be extremely competent to be able to program this on the control panel. You would probably need a masters degree in mathematics as well! Mastercam doesn't set the tools up for you, either.
Eddie J. Parsons The only time you need mastercam or others CAD/CAM software program in this case is simultaneous 4 axis milling. I didn't say it is easy to make this part on control panel. The easiest way is to use some CAD program (can be mastercam again) to find exact points for tool. There is too much calculating to do it manually because of eccentricity.
Mariusz Rodziewicz I use Solidworks (models) and AlphaCAM Mill/Lathe (machining). AlphaCAM is all you need, I definitely wouldn't recommend Winmax for beginners, it's a dreadful software.
If you watch this video and think that machinists are being made redundant, you are not looking far enough ahead. The human race is being made redundant.
Very inetresting automatic CRANK SHAFT all operations machining is very good. I could not observe inherent Q C measures if any tool chip off...etc. IT IS VERY GOOD. S S Rao

There's no info on their website. Thank you!
There's no info because you have to quote(?) them for the price, but several hundred thousand is good guess to start with.
Loukas Dimitriou Hello - If you would like to make an inquiry, please visit our website and use the machine inquiry form. The machines are typically configured and quoted after through review of your application. Thank you for your interest.
***** MARTECHcnc thank you both for your reply!
its crazy that one bar of aluminum,or steel, or whatever it is can be shaped in to something so different. Amazing
Swiss lathe machinist here. I love watching big pieces get machined
That’s a work of art both in planning and production.
OMG! it is amazing, i love it.
"I swear, Oscar, if I find one thing wrong with this next crankshaft we're melting you down into cans" -Manager
I´m lost for words. Awesome! Great work :)
Had a guy taping me doing some cutting on a Okuma 5 axis lathe a few years back. He was begging me to run it with the door open for a better shot. Had to laugh when i said, are you going to hire me after they see the film and fire me lol because it would have been the end of my job given where i was at the time.
that is goooood leson
thank you
Thank you for a great video! Is that the crankshaft for an engine? Looks to me like a triple or, more likely, a V6...With staggered crank pins on number 1 & 2??? More info would be appreciated!
This Crank is not for any specific engine. It is merely a Demo to showcase the machines capabilities. Cycle time for this part is about 2.5 hrs.
@@MARTECHcnc Ah ok, I was getting really confused as to what kind of engine this thing belonged in! 🤣
G96 constant surface speed turning! I am a cnc lathes and screw guy. One slick machine here!
This is more awesome than the Robots in the Pacific Rim!
Need a crankshaft for a Merlin engine!!! :)
How is amazing you see a machine making a good work, using excellence in software and trained employees 👏. Congratulations.
The guys who programmed it should be honoured! 🙏
What engine is this for? Seems strange to have slightly off set pistons on the same throw, then a perfectly aligned pair on another throw.
It's just a demo crank, it is to show the machining operations that this particular machine can do. This crank shaft will not run in a car.
However, the split journals are for even fire v6's, so there are vehicles that run the split journal style crankshaft.
autofixation It looks like they've got multiple style journals on this. Some single, some dual. I will say this: Audi/VW loves to use that split throw style setup, I've seen it multiple times in their 2.7 V6 engines.
This is strictly a demo crank to demonstrate the machines capabilities.
I didn't think this was ready for an engine either. The con journals didn't seem to have a final finish on them.
6:57 - Interesting to hear the RPM increase to hold the surface speed constant.

Wauw what a huge groove tool. And no vibrations... Amazing machine
Cuts coming off like a steel ruler, what a bit of kit compared to the old days!
How many crankshafts did they destroy to program this right. Or do they use wood?
Impressive!
With today's modern software, complex components like this crank can be programmed and the program/tools 3D Modeled. Most of our users are working with very expensive alloys and/or castings. Trial & Error or scrapping out the first few "test" pieces, is simply not an option. No wood used.
This was probably programmed based on a model in solid works, module works or some similar cad program. All the tool paths were programmed there based on the precise footprint of the tool. As it is an improperly programmed CNC mill won't generally destroy the work piece, but rather its tools with improperly set feeds and tool speeds, which is often times a more expensive error than if the mill just destroyed the work piece with an improper cut.. With a large piece like this likely not, but often you'll be working smaller parts like fittings, adapters, or spacers. Where the cost of the material is far below the cost of the tools.
At 4:50 it sounds like Inception sound effect
Amazing.i never see this before!!
great vid technology is moving pretty fast it will be amazing to see what we will be able to engineer in the next 10/15 years !
This is pornographic...
Max Bender I would have thought you'd import the 3d model into the CNC software and it would automatically generate a g-code ?
grame141 I'm pretty sure that you have to set a strategy for it to follow, and that you have lots of of choices in the process that follows. I've only done some more basic cnc milling though.
The software will create its own paths which you can alter but the g-code is automatically generated. it's possible to alter the code afterwards but there's no instance where you would have to manually write the programme yourself from scratch. At most you would have to make some corrections after running a simulated cut.
grame141 grame141 - you are pretty much on track. First a model would be created, then the file imported into the CAM software. Tool selection and order of operations is interactive as part of the software package.
MARTECHcnc Absolutely AMAZING that so much can be done on one machine and with such precision and speed. At 13:22, I believe it shows the surface for the connecting rod bearings. There must be another, final step to make that surface sufficiently smooth and round enough for bearings. How is this step performed?
this is some seriously serious shit! I'm guessing this was programed by a computer where the dimensions/parameters of the object were given and the computer derived the code to make it work. If it was programed by a human or team thereof they are some bad mfkrs!
+Louis Balboa all CNC s work with CAD inputs that means it was first designed in PC by engineer and CAD programmer then CAD design was done by CNC like a 3d printer roughly.
It's not programmed, just a guy eye balling it while controlling a joystick.
R. J Patt ... Ha Ha
Jaxxon: Yes, the typical method on a part like this would be that the part is first designed by CAD and then processed by CAM software.
Is anyone there 2023?
2024 😬
This is not work...this is pure art!
one of the best videos!
When you use some CAD & CAM program like Mastercam or NX it is not so difficult to make this kind of part. I can even say it is quite simple because this program calculate for you everything. Of course it is possible to do this kind of part manually on control panel as well. You have to just focus on 1 operation at the moment and then when you done with this one just proceed to next one. No rush! Quality first :)

You would have to be extremely competent to be able to program this on the control panel. You would probably need a masters degree in mathematics as well! Mastercam doesn't set the tools up for you, either.
Eddie J. Parsons The only time you need mastercam or others CAD/CAM software program in this case is simultaneous 4 axis milling. I didn't say it is easy to make this part on control panel. The easiest way is to use some CAD program (can be mastercam again) to find exact points for tool. There is too much calculating to do it manually because of eccentricity.
Mariusz Rodziewicz I use Solidworks (models) and AlphaCAM Mill/Lathe (machining). AlphaCAM is all you need, I definitely wouldn't recommend Winmax for beginners, it's a dreadful software.
Mariusz Rodziewicz
I agree
It seems most of the ''former cnc programmer '' of this comment section have no idea what they're saying
More of these would be good and yeah, this is porn!
Looks precise as hell
Very interesting see how a crankshaft is made and also the amazing of the CNC machines.
If you watch this video and think that machinists are being made redundant, you are not looking far enough ahead. The human race is being made redundant.
gotta run and program that sucker, it doesn't just do it by itself.
+BA_300_AAC Not yet . . .
someone already said that.
no, more skills are being developed, for instance the 100,s writing the programmes to do this
Very inetresting automatic CRANK SHAFT all operations machining is very good. I could not observe inherent Q C measures if any tool chip off...etc. IT IS VERY GOOD.

Great Video and great info I enjoyed watching keep up the good work!
Dont think Ive ever watched a youTube video that long, and had it go by so fast. Thanks for making it up. Bad fuckin azz!!!
I will report this video for pornographic material
someone ought to..I almost had an organism watching this.
gbin21 xwow
too much cleavage .
The camera man is a pro, just look at the shots down low, from behind,you dont learn that from a book
