I've noticed whenever AI generates anything structural or integral, it tends to look very organic and cellular. It has always been interesting to me.
Well it draws inspiration from the intelligent design of nature. The design that is created by the one and only all knowing intelligent creator. The One, the all Mighty and the Absolute, Lord of the heavens and the earths ALLAH. Glory be to him.
Try reading the Quran, the holy book of Islam. It is the words of Allah the all Mighty. I urge you to read it critically not blindly and you will mesmerised by it and how it could predict all the facts stated within it 1440 years ago. Facts that could have never been made by a man, who doesn’t read or write, living in the dessert 1440 years ago. It is a miracle book.
This is no cheesy comment, but a serious invitation. Just try reading it sincerely, with the intention of finding the truth.
Reminds me of the Japanese engineering of the bullet trains using inspiration from the kingfisher.
That tends to yield the optimal performance when things are designed organically
yeah that one seater sports car that is largely AI designed as well, extremely organic.
@@viboldsok Japanese also used a fungus to design and optimise the train network
I'm super impressed with that fact that Rob is basically at the point that that parts he needs are being made in house
Lol i fken wish i had a milling machine, i had to ask on a shop for a custom bushing because my 15 year old mountain bike's shock blew and the new one has a different diameter (i'm going from a Fox DHX 5.0 from 2009 to a 2019 DHX2 Factory series), with the bushings being frame specific it means that what i need simply does not exist. Hopefully it comes out great and doesn't cost much, otherwise i'm kinda fked.
@@buildaboiworkshop it needs to sustain forces of over 400 Lbs or 200Kgs on rough landings i don't know if i would trust aluminium with it. I don't have a 3D printer either and i don't think precision would be good enough to press fit one in without lots of trimming and testing. I called it a bushing but it's technically just named "mounting hardware" there's no real name for the component i'm talking about. The original ones on the old shock seemed to be made out of steel. Basically it's an adaptor for the screw that it mounts to for there to not be direct trunnion contact
@@buildaboiworkshop nah i just can't fuck around and take chances with stuff like that, any tolerance could end up with excesive wear resulting in extremely premature damage to the parts, plus i do not have the hardware i would need to make that work either way. It would also be kind of ridiculous if for some reason i needed to sell the shock and i had some crappy stuff done to it, it's very high end and it would be a total waste to do so.
I agree completely. This guy is after a bushing which is most commonly produced in aluminium but sometimes plastic (not particularly strong plastic either). I routinely turn these up when the factory part is unavailable and have even used a drill and and a pair of scissors as an arbitrary lathe to turn the plastic versions to length. People tend to massively overthink these things @@buildaboiworkshop
@@Ferrari255GTOjust a lathe would do
To save you some money in the future, buy some blocks of machining wax to use for your first tries of making the part. It can be machined much faster, and costs significantly less than the aluminum. Save the aluminum for the final pieces and use the wax for all your mistakes. Also, change your coolant out, looks like there's a lot of rust.
I was thinking the same thing about the coolant. It looks terrible
Yeah, i'd use some machining wax or other easy to cut material for prototypes or first off parts.
that "rusty coolant" is what they bottle and sell as keeps later.
This is the way. I learned some CNC in shop class in high school and it was all machining wax.
we used to use a something we called "rin" for aluminum vacuum forming prototypes. Its like a red plastic but i assume color can be anything. similar to delrin but way cheaper.
THIS is a proper use for AI, not creating content, not creating art or music, but for engineering, science and other similar stuff
But I love my AI girlfriend! Lol
@@Yz4Lifedoes your AI girlfriend make rotaries
Yeah unfortunately the main incentive will be making money through ads etc.
But is engineering also a type of art tho?
@@SpeedyJuiceMan Not theft tho, the AI platforms for engineering are not trained on previous ideas but just change stuff and see what works rinse and repeat
Hey Rob, they look awesome! But just for future reference, a properly torqued bolt will have significantly more clamping force than 100lb. A Grade 8.8 3/8" (M10) bolt torqued to 30 lb/ft (40Nm) will have around 6,600 lb of preload (30kN, 3,000kg). Even at only 12lb/ft (16Nm) there will still be 2,400lb (11kN, 1100kg) of preload. You may want a spacer tube between the flanges, unless you thread a bolt in the top and separate one in the bottom so that there is no compression between the two. With how thick the flanges are you may be okay though. Well done though, keep it up!
Oh shit! Thank you for explaining that!
Exactly what I was thinking!
@@RobDahm Also topology optimization does great things but it still needs to be tested against the real world forces
yeah seems crazy having the bolts trying to warp the flange. rob is definitely no engineer 🤣
@@muzzarobbothats what happens when a software guy ventures into mechanical eng territories😂
Very impressive! One thing though that I think will definitely help out. As a former CNC machinist working with high dollar parts, we NEVER ran new code or any sort of new setup at 100% speed. I get hard ptsd watching the tool fly into the part at full speed. We would always set the physical speed knob to 0% before ANY lines run, then turn it up a single click and watch it go line by line. That's what it's there for. It's been a while, but we used the setting that pauses after each line (forgetting the name at this point), so every new line of code we can start at zero, turn it up slightly and make sure it's doing what we expect. Any variable that could potentially lead to a crash, we would double check. It was very normal to have fucked up lines of code saved in our programs, typos, mistakes, issues with indicating faces, parts not chucked up as well as we believe, etc. that are easily caught from listening to the grinding when going slow. You'll save a ton of time, money, tools/material, and getting yelled at by the guy taking over on the next shift, trust me!
all true unless working with work hardening materials like inconel and many other less known ones.
Yes, this. Also using safe-mode helps a lot.
Single block is what your looking for and definitely remains on with my rapid @25% the entire time I’m running thru a new or un proofed program
@@jangelsantana2266 Yeah! Been a while since I've been on my Okamoto machines
@@EngineeringSiblings That's fair, I mainly worked with silicon carbide and tungsten carbide
This motor is literally the rotary final boss😭
Until you pull the same trick with the twelve rotor it did with the four rotor and put two of them together 😂
@@kugelblitz1557 one front.. one rear.. then mad mike drifts it.
ENGINE
@@slickman5969 engines are motors
A “motor” is an electrical powered device, an engine is an internal combustion engine that you find in cars,
If you want a good secret to see better through your door glass, get tempered screen protectors for the biggest iPad you can find and stick them inside... the coolant repels off quite nicely... I think the ipad pro is like 13"? We found out about this little hack and we've done it to every machine at work... Joel will thank you for the better quality shots... 😅
Rainx
I wonder if you could find hydrophobic/oleophobic film that is priced less than a screen protector? Gotta be a huge markup on anything for an "iPad".
lol 9:21 looks like they already put phone screen protectors on the window 🤣
@@jerrylancaster256 yip some sort of hydrophobic coating like rainx or never wet would probably work fine and is much cheaper to re-apply.
just get a rotary wiper/ spin window, works perfect for ave
Man those 20min videos fly by but we all were waiting 10 years+ to see this engine again
To any that are wondering about this, the process to develop these parts is called topology optimization and uses structural analysis to slowly whittle away the material that is not needed to meet the load inputs and space claim set by the user. Basically, the designer makes a model of all the space that can be used for the part and than sets design parameters, like structural loads or airflow requirements, than the CAD model is slowly and iteratively generated by the software. Finally, the model is cleaned up by the designer to ensure the part is manufacturable. This has been used by engineers for almost 10 years now. Very cool process and can save tons of hours in part development. I get to use tools like this at work everyday, so much fun. Great video!
More than 10 years. I'm actually shocked how far back the history goes.
... and it's not AI.
@@udsnamen2317 I was going to say that, but it depends on which program you are using now. I think the Autodesk program used in this video does use some AI. A lot of them don't though. I know Solidworks and NX do not use AI currently.
@@kornydad14 You are right, he might not be wrong using the term 'using AI' - it's a nice buzzword 😉.
As far as I understand, the AI helps the pre- and postprocessor and maybe with the optimization of the iterations, but the kernel itself uses the same 'old' math as before - just a little bit more sophisticated...
@@kornydad14 It's still not AI. Some people will try to defend "generative design" as AI and I would argue even that's not true AI. This is top opt and it requires no AI at all, it's just really good programming that's been tuned for decades.
More engineering prowess went into making these than the Haas F1 team in 2023
You mean Williams race team 😅
@cncaliguy09 to be fair Williams scored more than twice the points in the constructors race than Haas did.
Rob Dahm as the new Team Principle.
@@cncaliguy09 What are you talking about? Williams did phenomenal last year.
Haas CNC Machines the only thing that they can actually make work properly lmao
Yes! I have been wating so long for a 12 rotor update and it was so worth it I can't wait to hear this monster roar!
And it is incredibly impressive.
Dudes going to milk this project for YEEAAARRSSS
@@mostlymotorizednobody makes anything at all for this motor, he has to do almost everything in house. Making brand new parts on a motor people left alone because nobody wanted to take the challenge of building it
@@shaunsteele2943 what are you talking about it was already built
@@mostlymotorized if you know the motor it was a miracle it even ran to begin with and wouldn’t run for long at all. He’s fixing all the wrongs with it, he is rebuilding it to be better
Rob you need to put your coolant through a filter. Also put some urinal cakes in the storage troth 👍 it kills any smelly bacterial build up in your coolant system and it doesn't harm or change the coolant properties
20:25 ”it is actually hard, I’m hard” 💀 lol
im glad im not the only one who heard that
Topology Optimization has been around for decades. While it keeps getting better and better, there is nothing new about it, nor is A.I. required for it. Regardless, nice work. It's also nice to see these processes becoming more and more approachable.
Was about to say this. My professor back in '00 was talking about how he worked with VW on oil pans using this. Like you said, the big headline here is how affordable and accessible it has become.
Yeah, but gotta get them clicks. So AI AI AI all the things
@@Hobz79 as with many things, I learned about it because of Formula SAE. An alumni who worked at Altair told us about it at a competition probably around 2003.
It bugs me that there is so much hype implied in the thumbnail and title and substance of this video. This is practically a two-dimensional part there's nothing to it, and no ai required to extrude a .100" wall from a sketch.
@@mostlymotorizedclickbait . Funny how the peons clamber to anything affiliated with “AI” when AI doesn’t even exist 😂😂
It looks like its about time to change the coolant on the VF1. Id also recommend looking into getting a tramp oil separator and an aquarium air pump. This makes sure the coolant doesn't go rancid from lack of oxygen.
Coolant is the least of his worries. He would have been much better off hiring a competent machinist.
@@bdkw1why “hire out” when you have skills, equipment, AND can do it yourself.
@@One-way because he can't do it himself. At least not well. Or even half ass. Beating your head against the wall and making numerous stupid mistakes entertains people that have zero machining skills. Those that have actual skills just cringe.
@@bdkw1 Rob seems to be doing just fine. Thanks for your opinion tho..
@@bdkw1 and where did every "competent machinist" start out?
Most people see Steve Morris's channel & dont understand the insanely high cost of everything they're looking at. Along with the dynos its like the adult land of endless fun. Maybe some day we'll see a collaboration!!
This right here, Steve Morris is a guy who knows how to build insane engines that make shit ton of power but are still reliable as hell
Well done Rob! However.. What you used is a topology optimization, with the user interface being supported by AI. If you're looking to continue improving I'd suggest you look into topology optimization through FEA programs, such as Ansys. I believe those are probably better to work with, atleast if you know what you're doing.
Keep it up!
I would suggest nTop also! I loved using it on a project last year.
Is Fusion not using FEA to generatively design the optimum part?
@@Minerals333 That’s the point. Most CAD software has built in FEA tools, which are not as powerful as the ”regular” FEA programs.
@@Minerals333 I haven’t used Fusions new feature myself, but I assume that it just takes a few inputs, then makes a whole lot of different assumptions and then proposes a bunch of corresponding solutions. In FEA programs I believe you need to do more definitions, which in turn gives you ONE solution for a probably better optimized part.
@@Erik6635 gotcha, thanks for the explanation.
I think why i keep coming back excited for the next video because I can see myself in Rob and his team. He doesn't pretend to be a master at anything, he's always trying to learn the next piece to building his own instead of just paying a shop to do it all for him, and it just feels like he genuinely likes sharing what he has discovered.
Always awesome to see build progress.
I’m a machinist, I rarely ever use CNC but I do, and this is super impressive even for someone that’s been doing it for a while as I have. Love the work that the shop has been putting in lately. I know you guys were looking for machinists local, and I would, but I’m not local as of right now and I won’t be for a while. I’ve been watching for years and I love every second of every video
I've suggested it to AVE, and he took my advice years ago - you can practice CNC machining on wood
Do as much as you can without having to re-setup your part in the vice or fixture. Each time you move the part there is another variable added to your success equation.
I'm surprised he didn't do it mirror image and instead restarted from the middle. I would have thought it would be easier to build a wall it could butt up against and then when you swap sides you just put the other end against the wall saving time of trying to realign it everytime?
@@jono6379you don’t need to. You just use the prob to find the know hole point and the machine does the rest. Once it knows where that hole is in comparison to the rest of the part it in turn knows where the rest of the part is.
Yep. I would leave it attached to the vices and then flip the vices 180 degrees and re g-code the program flipped. I would probably even touch off again with the calibration probe.
I would buy a big block of this stuff called Corrien (spelling?) And I would fully run the CNC, check the prototype on the block? If it's all good then I'd chuck in the billet alloy (obviously adjusting the speed for material) click run and go and kick back and just listen to the CNC via "audible audit" just listening for any tooling issues or any swath interfering with sensors or what ever?
Kick back and watch CZcams till it's done
Any machinist knows, you probe to zero after moving the part, if done correctly it will be at perfect zero for next cut. Imagine how a 20' long piece is machined. Its in a mill thats 4' bed moved 5 times. So 6 operations..
m code is machine code. G code is from the software.
This is the epitome of “measure twice cut once” you guys are so brave and I appreciate you sharing the “failures” along the way. Bad ass 💪🏻
so proud of your progress on the CNC machining side of things. I remember when you got this and i was shouting at the screen "Rob there is a better way to run that machine" You've totally taken it to a high level.
I love this build, I'm super glad to see it coming together! I have a feeling on version 2 you will be running water through the block like a Steve Morris SMX block
Rob: PLEASE work with AngeTheGreat to simulate how this motor will sound! Your use of AI and his HIGHLY effective engine sound emulator would be a brilliant combination!
But why he can just find out for himself when he fires it up again lol
@@freedomfox8183 because it's the kind of collab Rob would enjoy. And, by extension, us. And because we can all learn new things.
The skill of your crew to get the camera to look closely, exactly at what you're describing and with clear focus always impresses me.
It's videos like this and like the super clean updated harnesses that we love to see. We get to look back at the early beginnings and see all the growth and the knowledge that's been learned and truly appreciate these milestones.
Rotary daddy Dahm blessing us with a video is rare nowadays 😢 Upload more please! Your rotary content is the best on CZcams! Hope all is well Grandpa Dahm 😂
Ohhhh boy been waiting for some Dahm content 😢
I mean right!?! Gimme the needle.
I’m watching rob do machine work right after I take a lunch break from machining for 8 hours straight still satisfying.
Just watching you get exited about machining these parts is great the passion outweighs the cost which is rare these days I have watched a lot of your videos they are all great can’t wait to hear the 12 rotor fire up for the first time keep it up all the best from UK .
Since you're not cutting all the way through the part on the sides, there's no reason to have it set so high up in the vices. Lowering it all the way down will make for a more stable set up, less chance of it moving, and probably less tool chatter. But still, it's cool to see AI designing these pieces.
I could watch CNCs run all day. Incredible what they're capable of 😍
I don't know if I commented the other day but Rob, I've been watching you FOREVER(From the 20 2step when you were unloading it 11 years ago). I love how much you've grow and how strong your knowledge skill set are. Keep it up boss I'm here for all your future endeavors!!
To get more space out of your HAAS, make a pallet for a lack of better words. Machine a cavity for your part at 45 degrees across your table. It will get you a lot more distance in X because it’s running in XY. Use Mitee bites. You will have one pallet for Opp 1 and one for Opp 2. For GD&T pickups, machine a small very accurate hole in the lower left or right corner, use that as WCS for pickup.
Am I missing something? Why are these 1 piece per column? You could've made this in 3 smaller, unique pieces (9 mid pieces, 2 sets of 3 angles) to cover all 3 columns of engine manifolds) and made them easily replaceable in case of an accident.
Removing that much material you may want to check the flatness of the flanges if it matters. Most materials stress relieve and flex at least a little bit
I'm loving the process, I'm not into cars per se but i enjoy learning about new things and i've learned so much so far, love it! I hope to see it run someday
I love how Rob always puts the "ee" in Keeps right over his face. 😂 It's a small thing, but it always makes me smile.
I wonder where that thing will end up... Maybe one c8 Corvette? Hmmm. Food for thought.
Edit: This is one of, if not the best engine building channel. While I understand there are other builders with channels that know more, have more experience, more results etc. Rob is bringing us along with his learning process as he goes. So much viewer interaction as far as an educational standpoint. What an amazing progression thats been thoroughly documented for our viewing pleasure. Thanks to Rob and his team. Truly thankful for your dedication. We should all be inspired. Cheers.
Just saying, but that would definitely fit right into a big block dragster, no adapters needed
The 12-rotor? It's meant for a boat, designed by Tyson Garvin to be a drop-in replacement for a Big Block V8.
it is massively heavy, would completely unbalance most sports cars. This needs to go into something large like a heavy duty pickup or a boat. If you put it into a car the thing would spin out around every corner. Yea i would put it into an F350 probably.
I think you better add some spacers for those bolts in order to get some tortion support when you tork them to specs.
I’m a beginner student to become a CNC miller. I’m just a half year into my school and i’ve designed a custom rear strut brace bracket for my mini cooper s r53 clubsport, i got recommended by a fellow mini owner and also fabricator the software Fusion360 seeing you work on this inspires me so much. Seeing the intake you make gives such a wow factor and such a push of ideas in my head. At the end i’m also trying to do what you guys do, being creative with cars and fabricating all kinds of stuff! Love the content and keep inspiring
Im no expert with CNC but the small amount of training i did get in it makes me appreciate the guys that make parts that have super tight tolerances and i love seein Rob learn it and explain the process because it is truly an amazing skill set and job
Just curious, why didn’t you guys use a block of oak or something on your first attempt to keep the cost down
How frequently do you have to drain/replace the coolant in the VF1? Maybe it's just me but it looks like it's a darker (dirtier) shade of brownish yellow than it used to be from your videos earlier in the year.
This stuff is next level cool. So fun to watch. All the best on your future progress, Rob. Cheers.
That design is awesome!! I can't wait to see that beast of rotary running and look forward to what you decide to put it in.
12:24 you should splurge and get those torque indicator bolts (or smart bolts) for this. I'd say it's worth it. It's AN expense, but it's one of those places where using this kind of technology will save you the grief long term. ALSO, you'll always know you're out of range by a glance, so if something loosens, you'll know it.
That transition into the ad was Dahm smooth...😂
Machinist here, and boy do I wish I was there the give you guys a hand, not because I think I can do better, but because there are just some things that could be done to ease the manipulation of the part, indicating, and proofing the program. . Y'all are definitely doing a great job. Take note of what goes wrong and why, and that'll make the next job a lot easier and go a lot quicker. This I've learned after machining parts for heavy mining equipment.
you should get an ave style spinning sightglass for the cnc so you can take more clear timelapses of the machining process. always fun to watch.
Where has Isaiah been
Did Isaiah leave?
Yea, he is rapper now called MexicanOT😂
most build I've been seeing are almost identical, this is the most unique thing I've seen so far. The only thing that would surprise me now if Rob turned out to be an alien and he got these plans from Atlantis. Can't wait to hear this thing fire up
Next level. Amazing how far u have come mr Dahm.
Man I’d be super nervous to mess up a 1k block of alloy.
Looks insane and super functional
Really great to see this 12 rotor progress. Great job on the machining.
This rotor engine is going to be a thing of brilliance..to see the progress and ingenuity you've made on this is beyond impressive..can't wait to see the beast in full force.
Absolutely love the work you've been putting in over all these years, this is going to be spectacular!
The 12 rotor is easily the CZcams project I'm most excited for and I don't get excited over much on CZcams
20:26 Hard, I'm Hard. That feeling you get when you accomplish great things. Priceless.
Doing the same thing on a tormach with 4 cylinders, learned on a Haas. Hats off to you sir its a lot to learn and take in.
This is ablsolutely beautiful! I'm into machining myself and I know how rewarding it is when you have to figure all that stuff out yourself but you make it work! After seeing this I am also going to play around with the ai generator in fusion. This already is amazing but wait untill you eventually upgrade to a 5 axis cnc, it will open up a whole new world for you!
Very cool stuff. I need to get some practice doing AI gen for lightweighting components because that is coming out quite good.
I used to run some CNC mills, they are amazing machines and way more complex than people think. Nice milling!
What an amazing job 💪🏼. Thanks for sharing you experience and great knowledge.
I thought the CNC machine would be a game changer, and here we are, Rob designing and machining his own parts.
From modern warfare to this, i cant believe how far you have come! You are genuinely my idol
Very exciting, good work. Really looking forward to 12 rotor content.
Amazing content and craftmanship more videos like this please!
That's awesome. Looking forward to seeing how you end up rebuilding this thing.
I saw a small clip on the CZcams channel of Throtl, about them saying the only one who's crazy enough to make the 12 rotor go 5000hp is Rob Dahm.
Next day Rob Dahm: 'This lightweight part holds 5000hp'.
My first day off in 4 months, starts very good with this video and some coffee!
How do you come up with the CNC programs? A explainer video would be interesting from you Rob, you're a great explainer too!
Rob watching the CNC Mill go is like me watching my design buzzing to life on the 3d printer.
Rob, you're picking up the machinist lingo! HAAS does have a great feature called distance to go. the idea is you can feed hold before you crash, slow down your rapid move to whatever is comfortable, and then look at the distance to go number and look in the machine to see if that "looks about right" and then push the f'it button.
Its probably gonna take a long time because it should take a long time, but i cant wait to hear the thing roar and perhaps even dynoed.
Its gonna be amazing.
Incredible beautiful design and machinecutting! Wow
The level of engineering happening now is so inspiring 🤯 Keep it up Rob and team!!
inspires you the get AI to do it for you too?
Rob you are my hero and live my dream. Greetings from Germany man! Once I drove a RX7 on the Nordschleife myself, Im addicted to the Brapbrap. Keep it going my dude!
Man those "Hans Devices Really Save Your Life" lol both the neck restraints and your cnc machine. Haha
DAHM Rob! Down the rabbit hole you go ~ self authored ❤
Keep up the amazing work Rob! You are really a wizard of engineering!
I like using generative design although this simulation based and not AI, it's cool to see all the progress you have made. From "giving a Smart Board to a Dumb Guy" to this, keep up the good work @RobDahm.
Nice CNC work! I do it for a living. Try a roughing endmill & slow down your feeds/ speeds.
What a piece of art! Just beautiful!
I'm super excited to see you guys get that monster running
Yes finally. I've been waiting for this build
This is incredible. Awesome use of AI. Great progress on the 12 rotor
I can't imagine what would happen if he got a bigger machine to cut projects like this. Way to use this machine to it's full extent.
Looking forward to the next one !!
Rob is the most inspiring CZcamsr there is. Thank for doing you and sharing the journey with us
You Always on Top of your Game Rod, Those Rails Looks Amazing 👽👍🏻✨
Nice work Rob! That part is sick
Feeling edged with the subpar cliffhanger but yall still living the rotor version of my LS dream factory
I've made some massive and very high tolerance parts with multiple shifts, it can be a pain in the ass but once you have a system it goes pretty smooth. What I like to do is ream a hole somewhere on the right side that is going to be machined out later, then when I shift I can indicate that hole in for XY0.
In about 3 videos Rob will be making a full tube chassis with his cnc machine... the progress is insane
I just brought a small cnc. Wholly hell Rob. Mad respect. Love from New Zealand as always.
Nz in the house!
Like your shop cat as well. Nice machining Rob.
Your next tooling purchase should be some fixturing and hold down clamps so you can lose the vise(s) and clamp your material directly on to the table. This would help with repositioning within your work window and more securely hold the work to eliminate the tool from lifting the material in the vise.
That's amazing work, Rob.... I hope it works!!!
Sir never give up on your work because you're doing legendary stuff in your garage and you'll be remembered as a legend in the future ❤
Excellent work. Nothing like the feeling of accomplishment.
