4 minutes in and I’m already blown away by your intense, excellent production values. I was a professional video editor back in my youth. I know of which I speak. Well done! It’s not necessary for every machinist to aspire to this level of quality, but it’s a joy to watch. Thanks for sharing.
Thank you very much - very kind of you!
T t. Tt t
As a retired machinist with 46 years experience, I must say.....nice work. Thanks for the video ( I watched the whole video) from Akron, Ohio, USA
Thank you very much -- and greetings to the United States!
That took me back.... the number of helical gears and shafts I made during my trade. Loved seeing it again. A dying trade with NC and CNC. Great to see thank you for showing this
Thank you very much-- you are welcome.
Thanks for taking the time to post an English version
It was a pleasure!
This is excellent. I should try to make one for my little Atlas milling machine. Looks like a fun project!
"Thanks for watching"...we should be the ones thanking you.takes so much time to complete the set up,& then the job.& then the video itself.quite inspiring.
Thank you very much--very kind of you!
And then editing it twice for two language! Guys a machine shop saint!
What an Exceptional job you've done there. Always dreamed of making a machine like this, Now I've seen you do it, I think I'll be seeing you for a set of gears if I need a set.
Thank you- this is very kind of you!
That is awesome! Great setup
Thank you very much!
I was looking for such a video. Thanks. СПАСИБО.
It just amazes me that this guy took his time to meticulously put together this video yet you have 96 haters. Guy thank you so much for putting this together, I learned more than a few things today. THANK YOU
Very kind of you! Thank you very much!
Ví el video completo sin siquiera saltarme un solo segundo. Me quito el sombrero ante usted.
Great video. Thanks! I’m subscribed and looking forward to watching more of your videos. One comment though, leave more time for viewers to read the written text, before continuing.
Thank you very much. I will give more time for viewers in the future!
Fantastic work Buddy, you have inspired me to try som new modifications, thank you 👍👍👌👌
Very impressive and detailed video. Very easy to understand. Please make Video Showing Step by Step procedure on how to Cut Spiral or Helical Bevel Gear on Milling Machine. Please include also your computation.
Thank you very much. Yes, in the future I'll try to improve the video and add the computations.
Now that is one gorgeous workshop.
Nice to hear- thank you!
You've done an incredible project.... Very very good.... Bravo
Thank you very much- nice to hear this!
A tooling ball is one way to find intersections of center lines with high accuracy. That's what I use. Good video, without a doubt.
Thank you very much for your response!
Thanks again that was awesome to see i love you and I,love your videos and your Chanel,,you ar riley master
This is very kind of you - thank you very much for your comment!
Die ganze Mühe die Ihr euch gemacht habt, nur um uns allen das verständlich darzustellen... Vielen Dank, das Video ist sehr nachvollziehbar! Grüße von der HS Osna
Vielen Dank - Grüße an die HS Osnabrück!
Entirely fascinating. The "skiving" marks on the involute teeth are interesting and I'd be curious to hear your thoughts on why they would not contribute to noise or dangerous wear in a working gear set, and what the dynamic is that contributes to them. Your cutter seems to have no detectable run-out and your change gears seem to roll smooth. I'd also be interested to hear your estimation of what AGMA rating a gear like this might have. I converted a Bridgeport turret mill to four-axis servo control in 2001 and subsequently built a servo-driven shaper machine in 2002 - both for cutting straight splines. They were in profitable service for years. I have always wanted to try to cut helical gears with the milling machine, but lacking an encoder on the mill spindle, knew I couldn't use a hob instead of a single form cutter. Our current project is the conversion of a 1950's Gould-Eberhardt vertical gear hobbing machine to servo control, using a Galil controller and two Yaskawa servos - one for down feed (not timing-critical) and the other to the rotary table worm (timing-critical, to an encoder on the hob shaft). Very excited to see it run. Whatever the case, your techniques here are outstanding and the video is beautifully shot / edited.
Thank you very much, Eric. The feed marks are due to the cutting process and professional made gears have them, too. These marks have no influence on noise or vibrations as literature states.
Hopefully and finally I found what I was looking for,,, pretty awesome thanks for teaching us I will always be tuned for all new lessons. Thanks for sharing.
Thank you- you are welcome!

You are ingenious and creative
I am trying under stand the diving head setup , amazing work sir
Appears as if it's servo driven.
Amazing video!
Thank you very much!
Great job figuring this one out. I had planned to do this in my own shop eventually. The only advice I could give, is leave the cutter running when you back up. It would have left much cleaner tooth faces. Also, climb milling in steel is very risky. It looked like you had enough room, to conventional mill on both gears. Much safer way to do it. Again... Good job!
How would you account for the backlash. I have used climb milling successfully many times to produce very long slender parts and very long thin parts where there was nowhere or way to clamp them only the force of the cutter holding them down. Like an airfoil shape out of high temp material 10mm thick 30wide 300+ long. First in a rectangular pocket that only exposed half of the thickness using a form cutter in a horizontal machine running the cutter over the part then filling the pocket partially with devcon forcing the part down into the devcon as perfectly as possible assuring flatness and alignment to the airfoil shape then repeating the process. The end of the pocket was the only stop and the pressure of the cutter holding the part in the pocket. You would think it would catch at the other end but it never did some say God protects drunks and stupid people I say that because I'm very aware that it should have could have if it would have grabbed the part and sent stuff flying like I say it never did and I never touched it I just stood there and held my breath, I must have made 20 ft of this material by this process.
This is very inspiring. Thanks for sharing.
Well done! Have you thought about using a 4 axis mill to shape helical gears by scraping/shaping? Yes, it would be slow compared to a dedicated machine tool like a fellows, but very handy for one-off prototypes.
Thank you for your Feedback! In my university institute we have a 4 axis mill, and yes, it would be possible to make helical gears on it.
Very interesting, thanks for posting your Vedic.
Wow! Nicely done. 👍
You are welcome!
Very interesting , always wondered how helical gears were cut.
You are welcome!
In a mass production environment, cutting one tooth after another is way too slow. The process is called gear hobbing: kzhead.info/sun/Y9anhMxummNve4U/bejne.html but you can image that alone the cutter costs a fortune ... but the method shown here can be done with simple machines.
@@stephanbrunker this great for custom gear 1 or 2. In a past life I worked in a gear shop for 28 years
A dedicated hobbing machine is like a screw maker. It's meant to spit out thousands a day. This is for the guy making custom transmission gears and the like.
Amazing. Very informative, educational, and inspirational.
Thank you- you are welcome!
From an ordinary human (me) who was not blessed like you with infinite patience, incredible precision, and the true mindset of a maker that makes all this possible ... my respects, my admiration, your work is truly incredible, I saw the video Complete 2 times and ...I envy your skill. wonderful work Sr.
Thank you very much - you are welcome!
Very good video man. The sound track seems to be like🤔🤔 when you are hearing the opening of knight rider 😁😁😁. Sounds from the 80's
Thank you very much!
Justo a beautiful job , it's amazing. Suscribed
Thank you very much!
Thank you for posting this video. May I know if there is any good reference book recommended for further reading? Thanks :)
Machinist handbook has a big section devoted to gear making.
awesome! looking at the geometry it appears that a longer helical gear could be cut with this setup, and then sliced into multiple copies afterwards, kind of like buying pinion wire, thoughts ? also you didn't show retracting the cutter while backing it up to return for the next tooth, but I suspect there's enough backlash in the drive to warrant doing so, thoughts ?
"Thanks for watching Thank you for posting this video ،amazing work sir
Many thanks!
I just bought a universal milling machine and I'm still trying to teach myself how to use it. Your MUSICCC is very INTIMIDATING and I started to doubt myself :(
I absolutely loved your work. I am an aspiring mechanical engineer and this was very interesting. Could you please recommend some books so I can understand more in depth?
machinist handbook. I think the latest is the fifth edition but not sure
Wonderful great job congratulations
Great job i still remember skill the cutter vibration must minimize excellent
Thank you very much!
Geniales Video, Alles ist sehr verständlich und Danke für den Verweis auf das Buch von Decker. :)
Vielen Dank - das hoert man gern!
MASTERPIECE!!
Very impressive skillset indeed. Are you going to make a new fifth gear ratio? I can imagine there is a huge demand in the car mod industry for your technique. Very impressive indeed.
Thank you very much- you are welcome!
There's a ton of one off machine setups like this for gears in the car world. This is the cleanest most efficient one I've seen by far though
Good job thanks is very help full
This is nice to hear -- you are welcome!
Exelente video, felicitaciones
Thank you very much- very kind of you!
the ominous music makes this feel like a strange horror movie with jump scares. im just waiting for a hideous goblin creature to jump out and make a wretched noise the whole time.
It reminds me my days of technical high school.
Thank you for your feedback!
Me too. My job was to calculate the gear train for the rotation ;)
Amazing ! - Very interesting video - You are a true genius ! 👍👍👍
Thousand thanks! You are welcome.
@@prof-rieg God bless you :)
@@BITTYBOY121 And God bless you. Best regards.
LOL reaming a hole though a non trued gear ... love it
Thank you!
This is a fascinating setup! How stable is the platform cutting hard alloys? I hope you don't mind my gleaning some ideas from you. 👍👍👍
Thank you very much!
Hi. What is the constant you applied to the rotary table, for the sequence of calculations of spur gears? Regards.
How would you determine the drive and driven gear for the rotation?
1 rev of the Work piece x Index Head Ratio (usually 40) x A/B x B/C = GearHelixLead / PitchoftheFeedScrew 1 x 40 x A/B x C/D = Lead/ScrewPitch A,B,C and D are your Gear Teeth Numbers.
This music is wild! I feel like I'm watching a science fiction space mystery
You are welcome!
It's amazing.
Your music made me think I was in a horror movie for a minute
Is this the only thing that bothers you?
So much skills & knowledge, blows my mind. Awesome video editing. I used to edit a lot. What's the music 🎶?
Thank you very much. I'm not dure about the music, I guess it is from audionautix.com .

How to find lead and table angle instead helix angle
Eres un crack amigo👍
Muchas gracias!
Nice job! What I can't figure is how you linked the cross slide to the diagonal?
The cross slide is fixed upon the helix angle. The helical movement is made by an independant electric motor which turns the dividing head and the spindle of the cross slide for forward movement . Hope that helps.
@@prof-rieg I saw all that, but what I recall from long ago, the movement of the mill table was directly geared to the radial movement.
@@mikemakuh5319 yes, that works if you can turn the milling table around the Z axis. My machine and most modern hobby milling machined do not have this feature.
I must be missing the reason why the rotary chuck dividing plate is turning back wards ,would it not have to stay at the same position so that the next count for the amount of turns can be done for the next rotation for the next gear tooth. As very interested due to I have my rotary table chuck set up with a Arduino and stepper motor which allows me to get the right amount of turns every time , i also am using the free program called Gearotic which allows one to get the math done for you just by adding the numbers very handy for a dumby like me.
Thank you for your Feedback. Indeed, the dividing plate has to turn backwards - like a screw. As a matter of fact a helical tooth IS a screw.
Please say, what a music is playing?
although this is great machining, the drive system for the dividing head can just use a stepper motor and a controller to change any size gear you need
Thank you! Of course, a stepper motor can do the job, too.
awesome music. what is it?
I watch the video till the end... (at least untill my phone giving low bat notification) Not knowing anything But I watched it anyway Was it because I watched something spining? Or the BGM...? Or both
You'll need a deep understanding in gears.
@@prof-rieg gears for me are easy, it's the dividing head
Very outstanding performance
Thank you very much!
I watched the whole video and it's amazing to see your creativity doing the mechanism for the spining table(makes me wish and want to build one in imperial measurements) Professor would you recommend me the same type of book in english?( Estudie en español elementos de maquinas,pero en ingles es un universo mas facil de alcanzar)my humble congratulations for your engineering creations, my best regards!!!
Thank you very much for your kind comments! However, I can't give you recommendations upon books in English, please consult Amazon and book stores with Internet representation.
machinist handbook has a fat subsection on gear making including these helical jobs.
Excelente trabalho
Sanatı severim 👍
Sir,, Thank you so much ❤❤❤
You are welcome!
👍 excellent!
Thank you very much!
I can see that gears come out very nice but seem to still have steps. Is there a way to improve it or how bad it is on higher load applications like car differential etc. Wouldn't it make howling noises at higher rpm?
To my opinion you'll have no problems even with higher load applications. These gears should work.
I want to try something similiar with module 1 gear cutters on my vertical mill. But using steppermotors instead. Ideally I'd keep the 90 degree tramming of the head as well, but that will complicate things a lot.
I wish you good luck!
Hi is there any chance that you accept orders and ill give you the specifications? Where can i contact you, thank you so much, great work btw.
No, i beg your pardon.
Spoken commentary would make this a truly excellent video. I don't care if you speak with an accent. There is a lot of information to be unpacked from just watching and the music had to be muted. Someone telling me what they were doing and why would also have helped. I have copied a link to my library for future reference. Thank you. richtig schön und danke
Thank you very much. Please see the latest Videos featuring spoken commentary.
Ain't nobody got time for that!!!
I think a CNC divide-head with some simple digital divide signal will simplify this process!
Yes, you are right.
@@prof-rieg kzhead.info/sun/mZioiKWjb6GDimg/bejne.html find a similar one, but this one is cutting with hob!
The helical gears were the AEI motors on the First V sets and the 7000 series cars
Thank you for your comment!
Lead gearing kasi karavi sir
Thanks god for my 5 axis cnc :-)
Find the job lead and gear train formula ?
I'm a 22 year old mechanic. After watching this, I think I want to go to school and get out of just being a tool guy.
This sounds good.
Go to Bayreuth and take his classes at the college. That would be a helluva awesome adventure

Thanhk you.
Hi Professor, begeistert schaue ich Ihnen wieder bei ihrer Arbeit zu ! Kaum zum Sattsehen ! Viele Grüsse aus Norwegen
Vielen Dank - da machen wir gerne weiter!
Would these be strong enough to make replacement transmission gears?
These gears were made from aluminium alloy. Such gears made from steel should work, especially if they are hardened and temperes after mechanical treatment.
@@prof-rieg what type of tooling would you need to cut steel?
@@cartermackenzie1135 the same type i.e. an involute cutter made of hardened steel.
The topic is interesting. Narration would've been better than text displayed in a video. And the music makes me feel like I'm watching a video from Dark5.
. *_who is the performer of music_* .
С конечно же фрезы СССР
An interesting exercise in gearing. Surely would have been 10 time simpler with two servo motors timed together. Still, great video.
Just imagine how much those of us that have used manual divider heads hated doing it lol
Why another table in the milling machine?
👍👍👍 Когда есть станки можно творить.
Я не совсем поняла твой вопрос

What is the price of gear making machines
Professional gear making machines are very expensive- a leading company is Gleason. I guess it starts from 200,000 US $.
Hai I am a beginner for gear cutting . I have a Grizzly milling machine go755. Can you do a video how to attach the universal dividing head to milling machine. Please it will help for all of us..
Guten Tag, woher haben Sie die Modulfräser, wenn ich fragen darf? Sind das die chinesischen, die man auf ebay, banggood etc. Bekommt? Falls ja, halten die länger durch?
Die sind aus ebay gekauft. Da werden oft Modulfraeser aus der UdSSR angeboten. Nicht teuer.
If you need gears to make a gears then what came first? Gears or Gear Makers?
Yes, that is a general question.
How are those cutters manufactured? That's what puzzles me.
Indeed, that is a very complicated manufacturing process. One needs a relieving lathe for the gaps between the cutting teeth either and for cutting the relief angle. Please refer to the according literature upon machine cutting tools.
@@prof-rieg , the gaps are the easy part. It's the relief and the conformity that's the 'puzzle'. We need a video detailing their manufacture.
