just like treads in a lathe, if the syncroniszation of the both the tool and the part isnt perfect betwen passes, its not the end of the world, because the next pass will remove on both front and back of the tooth. the speed on witch both turn can have some variation because the tooths have a desired gap. when everything is brand new, the process is quite straigh forward but when the machine starts to show age, any machining process that requires precision in every motion, isnt desirable

....I see what you did there 😏

Hi there It is an amazing process, Follow the link below and you will find a page with more information and a film that explains the process itself www.sandvik.coromant.com/en-gb/products/coromill_180/pages/default.aspx

эта технология довольно таки старая

Мы эту технологию изучали как зуботочение.Сорок семь лет назад.У меня справочник московское издание ,где подробно показана технология.Год издания-1985г.

If you only wanna understand how it works, you can try to imagine workpiece and cutting tool as paired-gears. If you wanna calculate it correctly, I suggest to read about "gear skiving", "power skiving" or "Wälzschälen". It's a funny process!

Hi, Yes, you can produce both internal and external helical gears with the Power skiving method. Take care

@@sandvikcoromant What can I do to avoid insert edge chipping in a skiving operation? I've already tried using a tougher grade, sharp geometry combination. Vc is 184, feed rate is 0.7 mm/rev. PCD is 198, no. Of slots on workpiece is 72, no. Of inserts in cutter is 42. Also how does one calculate Vc in skiving ?

Tipically PM-HSS or Carbide tools

Hi, Apologies for the late reply! There are several passes (cuts) to make and complete a profile. The deeper the profile, the more passes. If the profile is only around 1 mm deep, I would say 2 to 3 passes. Where the final pass has a depth of cut approx. 0.1 mm and the feed less to gain the best possible measurement result. The case we show in the video is a module 4 mm Gear profile (9 mm deep profile). We use totally 20 passes together at very high speed. We find the demo more impressive at higher speed. It is also possible to use some 10 to 12 passes for this gear but then at lower speed (Vc). We calculate for each customer case "Start cutting data" with a suitable combination of number of passes, speed and feed. Best regards, Sture Sjöö - Senior Special Tool Designer

Magical post-processing. I suspect this may be outside of the realm of Fusion360?

Lol. You could attempt Fusion360 to do this, but it will require a lot of lying to it. Fusion is not going to know what you're really doing with the code. As long as your machine is capable of syncing the rpm of both the spindle and table, the rest almost looks like straightforward facemill plungemilling tactics.

@@TomOConnor-BlobOpera only needs a couple of lines of code with a mathematical equation on it...

It depends also on the machine. But up to m = 5 mm is definetly not a problem.

This method is mainly used to machine gear components in steel, here you can read more about this method and our tooling solutions connected to this method. www.sandvik.coromant.com/en-gb/products/pages/gear-milling-tools.aspx

Hi, At the moment, we are able to deliver Q8 in accordance with DIN3962. Best regards Mats Wennmo Manager - Global auto transmission gear solutions

Swedish engineering

@@trancendmanapool but it's a german manufacturing process! lol

@@brunovargas3848 the technic was invented by a German engineer but the manufacturing process shown in this video is made by the Swedish company Sandvik Coromant

@@trancendmanapool correct!

Hi Andre, It's a DMG DMU 60 eVo.

@@sandvikcoromant What is the module?

Hi Andre, The size is module 4. Total profile hight is 9 mm. Take care

@@sandvikcoromant Do you think a GROB G350T can do it ?

It is a CoroMill 180, please see URL to webpage below. www.sandvik.coromant.com/en-gb/products/coromill_180/pages/default.aspx

that's easy. The society as a whole has a more equitable income distribution. The top end earns way less and it pays for part of the the benefits you just described. The other part comes from a higher tax load, but in the case of the Nordic nations, the taxpayers get it back in benefits. Not saying that it's right or wrong, just describing how they balance the books. I'm definitely not into debating the "rights" and "wrongs" of these policies on the internet. Everyone is entitled to their opinion.

German/American Gleason/pfauter company invented this method over 8 yrs ago..

Så är det.
