Very nice comparison, with the calculation of the MRR. As you wrote in the description it's important to note that between all those high feed techniques, only Prime turning from Sandvik is still capable of machining a shoulder. The last one in fact shows all of that weakness at 3:15
Prime turning tends to be slower in "conventional" materials, but we did a demo on some bastard carpenter material 2yrs ago and the prime turning inserts did REALLY well. Not particularly in terms of REMOVAL rate, but in DURABILITY, resulting in faster net removal rate. What do I mean by slower removal rate but faster removal rate? Due to the nose profile, the prime turning inserts get better wear in hard materials (all materials really). So the reason they shine in HARD stuff is because; if you have 12min of cutting to do, and a CNMG only lasts 7min tops, then your metal removal rate involves either a tool change or an insert index. If the prime insert lasts 15min, then you can finish a part reliably and change inserts without taking time off the part.
I like this response. Every tool company will claim to have the best tool for the job. Also, some tools are best for some applications but not others. The best thing to do is to try various methods and figure out what works best for a given application. Nickel alloys are some of the hardest alloys to machine. A company I worked at before going full time on my shop cut some Inconel and carpenter alloys and they ended up using ceramic tools for roughing.
Prime turning is really very good for harder materials. That is also our experience. In soft material (less than 30HRC), the chip breaking and durability of the insert is not so good.
On this video, I just pieced together some demo clips I found at the time to compare. There are some good options out there not in the video. I just looked up the TurnTenFeed and I like the look of it. I would say the best roughing geometries for high MRR will have some type of leading angle for chip thinning. They impart more forces on the part but for rigid setups with a good amount of material to remove they are a great way to go.
Nice video! Now I want to go buy a bunch of tools and do tool life comparisons! I really need to get a go pro so I can start making some videos! I used to work for Iscar, they just released the feed turn when I left so never got to run it, but the heliturn style inserts are pretty sick, had a lot of success with them!

You should add in the TurnTenFeed from Tungaloy, it blows the MRR of the others completely out of the water.

Спасибо за сравнительный анализ
Wrong. the sandvik is the fastest because it cuts forward and backward, and can also shoulder unlike the like 2.
interesting who is win?
nice but comparing to iscar lmox therrse no speed no feed no ap
vc278 f0.53 ap4.97mm
thats fast turning
not this b.....
CSK was faster
