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.

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!
@chauvinemmons3 жыл бұрын
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.

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.

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 just think that with your home made setup with cheap slide ways that you were indeed lucky to have got away with it and also too I think if the gears you were machining were made of steel that you will have had trouble. Personally I think that you stating in the video that Down Milling is safe, is a QUESTIONABLE statement. Thanks for showing what can be achieved on a home workshop setup.

@@prof-riegas i understand the difference with spur gear cutting is the work will rotate constantly to the the helix featured teeth. to accomplish that there is an extra setup that make the dividing plate to rotate which in turn rotate the work. so how do you make that setup? is that pre built from the company or you just created it??

Not a video to watch when your tired, LOL. I have cut a few Spur Gears but not any Helical Gears. Never really had the need to as yet ?? Interesting video to watch for sure

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.

An interesting exercise in gearing. Surely would have been 10 time simpler with two servo motors timed together. Still, great video.
