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?
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.
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.

These gears were made from aluminium alloy. Such gears made from steel should work, especially if they are hardened and temperes after mechanical treatment.
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.
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.
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.
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.
In a mass production environment, cutting one tooth after another is way too slow. The process is called gear hobbing: ua-cam.com/video/0rnTh6c19HM/v-deo.html but you can image that alone the cutter costs a fortune ... but the method shown here can be done with simple machines.
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.
@@prof-rieg seems to be a very good machine ! have u ever heard that there is a manufacturer in lithuania wich actualy makes the castings fro mr. prechtl ( golmatic seller ) have u perhaps ever seen one for these lithuanian machines aswell ? i am interested if those from lithuania have the same good finish on them
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
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.

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.
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 ?
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.
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.
@@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.

Same tools (cutters) for spur and helical gears? Only helical is cutting under angle. But then parallel cross-section is not equal on spur and helical gears (because of that 20.7° or 29.4°rotation of the profile). I thought they should be equal.
Yes, indeed, sane cutrers for both spur and helical gears. In fact, with increasing helix angle an very small error arises but this is tolerable up to helix angles under 30 degrees. Hope that answers your question.

@@prof-rieg Thanks for your reply, it looks like Germany is out of kilter with the rest of the world then. UP milling as you call it, the rest of the World knows as Conventional Milling and your DOWN milling is called Climb Milling. In general terms unless you have a brand new machine or your machine has Ball Lead screws, then DOWN milling is quite a risky business. Any slackness in your lead screws will cause the work to be dragged into the cutter and can cause nasty accidents.

I know why you're making them in Module 2.5. Because *nobody* makes MOD 2.5 gears as stock gears. They had a period of popularity in the late 1970's through the 80's then the entire machine tool industry decided nobody was going to use MOD 2.5 gears on anything. The cutters are still available used, or new by special order. But if you have a broken MOD 2.5 gear you have to make it yourself. The exact same thing happened with 14 Diametral Pitch gears after WW2. Many smaller lathes and other machine tools used 14 DP gears, mostly in 14.5 degree Pressure Angle. But shortly after the war the whole industry decided nobody was going to use 14 DP gears. There is one company in the UK which claims to have stock 14 DP gears, but only in 20 degree PA. 20 PA was uncommon in the 1940's and earlier when most spur gears were cut to 14.5 PA. So if you need to replace gears of this pitch and these pressure angles, it's a DIY job. What makes this even more annoying is that 2.5 MOD's tooth size and profile is >thisclose< to 14 DP 14.5 PA. The machinery industry recognized a need for gears with that size tooth but instead of resurrecting 14 DP they created 2.5 MOD, only to have the size exterminated a second time. A similar tale is how the variable speed drive industry apparently unanimously decided some time in the late 90's that for 3 Horsepower motors they'd all quit using a single keyed shaft on the spring loaded split sheave on the motor and switch to a splined shaft. So if you need parts for an older single key sheave you have to make them yourself, or figure out how to retrofit the motor sheave to a splined version. I have an ACRA knee mill from 1990 and had to make the plastic bushings for the split sheave when the nylon originals broke.
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.
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?

The cutters are still available used, or new by special order. But if you have a broken MOD 2.5 gear you have to make it yourself.
The exact same thing happened with 14 Diametral Pitch gears after WW2. Many smaller lathes and other machine tools used 14 DP gears, mostly in 14.5 degree Pressure Angle. But shortly after the war the whole industry decided nobody was going to use 14 DP gears. There is one company in the UK which claims to have stock 14 DP gears, but only in 20 degree PA. 20 PA was uncommon in the 1940's and earlier when most spur gears were cut to 14.5 PA. So if you need to replace gears of this pitch and these pressure angles, it's a DIY job.
What makes this even more annoying is that 2.5 MOD's tooth size and profile is >thisclose< to 14 DP 14.5 PA. The machinery industry recognized a need for gears with that size tooth but instead of resurrecting 14 DP they created 2.5 MOD, only to have the size exterminated a second time.
A similar tale is how the variable speed drive industry apparently unanimously decided some time in the late 90's that for 3 Horsepower motors they'd all quit using a single keyed shaft on the spring loaded split sheave on the motor and switch to a splined shaft. So if you need parts for an older single key sheave you have to make them yourself, or figure out how to retrofit the motor sheave to a splined version. I have an ACRA knee mill from 1990 and had to make the plastic bushings for the split sheave when the nylon originals broke.
Thank you for your very interesting comment - I think this is quite new even for advanced amateur craftsmen. Thanks again.
I think a CNC divide-head with some simple digital divide signal will simplify this process!
Yes, you are right.
@@prof-rieg ua-cam.com/video/f4oXAk8oMW0/v-deo.html find a similar one, but this one is cutting with hob!
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.
CNC hobing programing kese hota hai video dale
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
С конечно же фрезы СССР
Amazing video!
Thank you very much!
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.
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!
Amazing. Very informative, educational, and inspirational.
Thank you- you are welcome!
No puedo expresar en ingles lo intersante de este video ya que no domino muy bien el idioma ingles pero es importa y me gusta este arte, esta profesion y todo los conocimiento que hay en esteoficio .
Me gustaria conocer mas sobre algunas informacio que es de gran utilida para el uso de esta profesion .
The rotation of cutter should be against the feed direction
Not always: This milling machine has very few play in the spindles and guides allowing down cutting.
Thank you so much ❤
@@heavengamage9079 thank you for your response!
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.
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 ;)
Geniales Video, Alles ist sehr verständlich und Danke für den Verweis auf das Buch von Decker. :)
Vielen Dank - das hoert man gern!
Justo a beautiful job , it's amazing. Suscribed
Thank you very much!
Wow! Nicely done. 👍
You are welcome!
"Thanks for watching Thank you for posting this video ،amazing work sir
Many thanks!
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.
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
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.
This music is wild! I feel like I'm watching a science fiction space mystery
You are welcome!
LOL reaming a hole though a non trued gear ... love it
Thank you!
awesome music. what is it?
I was looking for such a video. Thanks.
СПАСИБО.
Your music made me think I was in a horror movie for a minute
Is this the only thing that bothers you?
Great job i still remember skill
the cutter vibration must minimize
excellent
Thank you very much!

*_who is the performer of music_*
.
Find the job lead and gear train formula ?
In my opinion the whole video could of used more machine shop sounds ie. Grinding, milling, bitching at the bandsaw guy for not cutting straight.. and less of the Xfiles themed music where I feel like I was being abducted the whole time amd about to get probed, but on the plus side of things.. Great video. Enjoyed the whole process and seeing your skill level. It was interesting to watch. Thanks for sharing.. 😎
Thank you - you are welcome!
I'm surprised to see them reaming parts on top of wood as the wood surface could affect perpendicularity.
Lead gearing kasi karavi sir
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!
What kind of Witchcraft is this?
Excelente trabalho
Этот станок самаделный?
да
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.
