The UNREAL World of POLYGONAL TURNING | Swiss Machining Genius

[@Kardos55]

This was my final year project about 40 years ago . . . we called it orbital milling in Europe, because we drove the multi-inserted tool with orbital gears and the part was stationary. This Swiss solution is much faster and easier to adjust.

This channel has seriously become one of the most interesting and fun machining channels

[@leonschumann2361]

it is both theoretically since both the tool and part rotate. but since the cutting speed has to come from the part turning by a significant amount, and you wouldn't do it on a mill, l would very much say it's polygonal turning

[@JFBence]

Yes. And even the workpiece-tool relationship is closer to turning.

[@leonschumann2361]

@@JFBence and l guess you programm it like turning

[@tdg911]

It's really amazing when you take a high tech machine, couple that with a very skilled and knowledgeable operator to be able to show what these machines are truly capable of. I think its also safe to say that the limitations are within our mind as well. Very cool video and project. It would be nice to see a competition of 'the most complex machined part' between you guys. But I think I know which department would win after touring your shop and seeing those complex parts. I don't think that competition could be judged fairly though when putting some thought into it. Everyone brings their special niche to the table which when combined equals an insane powerhouse of expertise. Keep up the great work! Much love and gratitude. BTW when is the next Boombastic!?

[@Triggerfigure]

i am a trained toolmaker we didn't have a cnc lathe but a cnc milling machine. if we wanted to create cnc turned parts, we put the lathe tool in the vice and the turning blank in the milling machine tool holder and created the parts that way

[@markregler2164]

How convex or concave is the flat then? 🤔 would be interesting to see just how tight a tolerance can currently be held

[@dannybolinger7985]

I noticed he didn't mention tolerances.

[@thoughtlesskills]

If this is actually useful in a shop, I imagine it's very rare. Makes for a great vid tho

[@donniehinske]

It comes out more that than I was expecting. It was a few weeks ago but I am pretty sure the squares were flat within .001-.002. the Hex was a little more concave at .003 but If I had used more inserts at a different ratio it would of been better

[@Orakwan]

The diameter of the live tool as well as the ratio of rotation between part and tool have an effect on the concave effect. Usually there is never tight tolerances on angled polygons, and for flat polygons, well concave doesn't change anything because the wrench grips the edges of the polygon, which is what your caliper reads also

[@BenCzech]

Okay, I'm hooked. I came here from this old Tony, definitely a subscriber now. You guys are awesome!

[@BillGriggs]

I'm curious, do the flat edges have a slightly concaved surface or are they truly flat?

[@donniehinske]

The square was flat within .001 and the hex was flat within .003. If you did 3 inserts instead of 2 the hex will be flat within .001

[@cyber2526]

[@aoiattentiononinvention8031]

Tilling. Millurning. Seriously though, y'all could name it whatever you want, it would be in the machinist dictionary by next year. You ALL are changing subtractive and additive manufacturing for the better, in sooooo many ways👍👍 THANKS

[@itzac]

That's shockingly simple. Absolute genius. I'm new to your channel and CNC generally. You probably answer these questions in other videos, but: 1. For that staggered offset effect, I assume you're just briefly pausing the tool. How do you do the timing to set the alignment of different faces like that? 2. You mentioned concavity, which I assume is caused by the circular motion of the tool. It's reduced because the part is also turning, but doesn't that also depend on the radius of the tool and the part? Do you have to compensate for that?

[@donniehinske]

1) if you are talking about the squares the staggered effect is done with G53 C"" so square 1 is G53 C0, 2 is G53 C20, 3 is G53 C40 and so on in 20 degree increments. This offsets the phase offset from your live spindle to your main spindle. each square is 20 degrees apart 2) yes you are 100% correct the fact that the part is rotating into the tool is what reduces the concavity. the square was flat within almost .001"

[@markdavis304]

Yaaaassssss! More Slow Motion!😎

[@GrumpyMachinist]

And for 7-9k you can have this attachment too. We've got a ST-38(triple turret) that we're outfitting with some new live tooling attachments and the cost is insane. The machine cost nearly a half million and we have nearly another 100k in attachments. If you are thinking about buying a swiss lathe just know it's not for the light hearted... I highly recommend ph Horn tooling. Costly but top notch.

[@TommiHonkonen]

yeah well they cost money they are not expensive but valuable. Just think about this, mill turn with 80 tools and 12 position revolver, look at 500-1000 for each on the tool changer and 500-2000 on the revolver. Just to start with. What you actually get is entirely different.

How to avoid concave and convex ... any idea sir?

[@chipper203]

Polygon milling is so cool, I use it on quite a few parts I produce. One thing I have not been able to figure out is how to time the polygon milling with other features on the part without physically rotating the polygon mill on the spindle. If anyone knows the answer I would love to know!

[@donniehinske]

It’s more on your machines capabilities than anything. I used G53 CDR0 (R0-360) to set the timing of the live tools spindle to the main spindle. You will notice in the part the squares are all 20 degrees apart from eachother. If the machine can’t sync your live tool in the same spot everytime like that then you are kind of screwed. What machine are you working on? I may be able to help

[@chipper203]

@@donniehinske thanks for the reply, I’m running Hanwha XD-20h machines. My polygon mill is in a front working slot on the sub side. It is driven by the sub spindle. I have never tried that line of code you mentioned. All my polygonal work is on the same plane like a simple hex shape. So I only need to orientate the cut at setup.

[@donniehinske]

@@chipper203 ah I see! I’m not sure if that code would work on a Hanwha. I’ve only ever worked on a few of them so I don’t know the code as well as I do other machines. I am sure there has to be a way to do it though

[@MetalMetz88]

does this method have a max diameter cutoff limit? seems like it'd stall out cutting a 5 inch square.. i'd love to try that on some 5-8 inch squares

[@Chris-du7hi]

I'm going with turning. Turning: the action or skill of using a lathe. Lathe: a machine for shaping ... material by means of a rotating drive which turns the piece being worked on against changeable cutting tools. So part go round fast = lathe and lathe = turning.

[@GhulamHussainEngineeringWorks]

Great working beautiful boom 💥💥

[@edmundzadurian8908]

I liked the concept

[@xaytana]

Turning is rotating an object with a static, by reference, tool. Milling is rotating a tool with a static, by reference, object. This has both a rotating tool and rotating object. So at a surface level, it could be considered both. But if you want to get stupidly technical, it's primarily a lathe with a manipulated mill-like tool; the object is constant, the tool in reference is not constant in position. So technically intermittent turning at rates that are inhuman to accomplish. You could hypothetically produce similar results without a mill-like tool, just adjust linear position of the cutter at stupidly fast rates, essentially a robotic cross-slide; very similar to the concept of a rose engine, but different in execution and at much faster speeds. Thus intermittent turning should be the proper term, because the mill-like tool only simplifies the process mechanically, though this is at the sacrifice of the linearity of the polygonal sides. For example, if you put a fourth axis on a mill, does the mill also turn into a lathe? No, because of which part is rotating and which part is static by reference. It's the same here.

[@juanmazapan9044]

It is poligonal topology turning?

[@TheSamurai0622]

How much of a larger scale can you go with this? That will fit in an NLX2500 or NLX2000.

[@donniehinske]

I am not entirely positive as to when this will happen but the bigger your diameter of your shape gets. The more concave or convex it will get but yes on those machines I am pretty sure there is a Polygon turning option

[@ignazachenbach5406]

well i think both terms turning and milling are right, since you are still turning your material, but you are also spinning a tool

[@dabooom1296]

But why is it able to cut straight with a turning tool?

[@MrMartinSchou]

As someone who isn't a machinist, I would think it's mill-turning or turn-milling. To my mind, milling is a rotating tool while turning is a rotating part. Since you're using a rotating part and a rotating tool, it would be both milling and turning at the same time. So mill-turning or turn-milling.
